In 2010, GM, inspired by the idea of ​​downsizing, released its next engine. From a 1.4-liter volume, thanks to a low-pressure turbine (about 0.5 bar), 140 hp was removed. This power unit in the Opel model range is known as A14NET, and among Chevrolet models it is known as LUJ. The 120 hp versions of this engine are designated A14NEL and LUH, respectively.

The 1.4-liter GM turbo engine is widespread not only in Europe, but also in the CIS countries, as well as overseas - in the United States. Thanks to the "through" displacement, cars with the 1.4 Turbo engine are gradually arriving in the countries of the customs union. In this case, we are talking not only about compact Opel models, but also about the Chevrolet Cruze and Buick Encore, purchased in the United States.

Motor problems 1.4Turbo (A14NET / LUJ). Ventilation of crankcase gases

This engine as a whole does not cause serious problems, but it does have some congenital "sores" that have been recognized by the manufacturer. During the warranty period, these problems were fixed free of charge, but most often they manifested themselves after the expiration of the warranty period.

The crankcase ventilation system is especially troublesome. As with any turbo engine, engineers had to go to certain tricks to implement it. But practice has shown that the quality of the implementation of these tricks is lame. In fact, 100% of A14NET / LUJ engines have encountered crankcase ventilation (CGV) malfunctions.

All three components of the VKG system fail:

• a diaphragm located directly in the plastic valve cover;
• check valve in the plastic intake manifold;
• corrugated hose from the intake manifold to the turbine.

Usually problems happen with the first two nodes of the VKG system.

Signs of problems in the VKG system of the 1.4 Turbo motor (A14NET / LUJ) are:

• increased oil consumption (oil burns out in the cylinders or in the exhaust manifold, seeping through the turbine cartridge or will go out through the oil seals and / or through the valve cover);
• smoky exhaust;
• a hissing sound in the engine compartment (bleed sound);
• floating speed or triple engine;
• decrease in engine power;
• increased fuel consumption;
• computer diagnostics will show the following errors: P0106, P0171, P0299, P0507, P1101, P2096 (they indicate a lean mixture or a difference in the calculated and actual air flow);
• an indirect sign: the inability to unscrew the oil filler cap or after unscrewing it or removing the oil dipstick, the engine speed begins to float.

Due to the failure of one or another component of the system, the pressure in the crankcase and in the cavity of the valve cover will greatly increase under the action of the air pressurized by the turbine. You cannot ignore the problems with the VKG system: incorrect mixture formation and detonation occurs, oil is squeezed out and shaft seals are worn out, the catalyst is clogged, spark plugs fail. Due to the high pressure in the crankcase, oil from the turbine cartridge stops flowing into it and is instead squeezed out into the turbine or compressor section.

What to do if the crankcase ventilation system malfunctions?

First you need to make sure that the malfunctions really concern the VKG system. To do this, do the following:

• open the hood and remove the decorative cover from the motor;
• on the driver's side, on the plastic valve cover, we see a round casting (see photo below);
• the casting contains a rubber diaphragm-regulator of the VKG system;
• if it collapses / breaks, then when the motor is running, air is sucked in through the hole, simultaneously making a whistling sound. This whistle stops when you plug this hole with your finger. In this case, the engine speed may start to "float", vibration will increase.

This casting contains a rubber diaphragm for the crankcase ventilation system. When the diaphragm is destroyed, air is sucked in through this hole (in some cases, crankcase gases are blown out from here).

Regardless of whether you are convinced of the operability of the diaphragm, you need to check one more element of the VKG system. The engine must be turned off. Then you need to find the place where the corrugated hose connects to the plastic intake manifold. The hose must be disconnected by first removing the bracket that fixes it.

At this point, blow-by gases enter the intake manifold and, through a hose, into the intake tract in front of the turbine. Thus, ventilation of the crankcase is provided. The valves block the backflow of gases from the intake tract (where, due to pressurization, the pressure is almost always high and there is no vacuum, as on an atmospheric engine) back to the crankcase.

After disconnecting the hose, you need to look into the hole in the intake manifold. The mushroom valve "nipple" should be visible there. It is clearly visible in its bright orange or red color. In some cases, you may need a cotton swab, soaked in solvent: It can be used to grope and lightly clean the valve to make sure it is present. If it is not possible to detect the valve either visually or with the help of a stick, then it simply does not exist. The fact is that the valve simply rips off the seat, after which it flies off somewhere along the hose towards the turbine.

The Mushroom valve of the VKG system must be present in the intake manifold.

The next step is to check the patency of the entire hose and the operability of the second valve located at the point where the hose is connected to the intake tract near the turbine. It is necessary to blow into the hose - while the air must pass freely. And then you need to "inhale" from the hose - while the air from it (ie in the opposite direction) should not pass. Often, the hose simply cracks, which causes air leakage. If none of this happens, the entire hose must be replaced.

To solve problems with the VKG system, it is necessary to change the plastic valve cover (there are already proposals for used ear covers with a rebuilt diaphragm), a plastic intake manifold (since the check valve located in it is not supplied separately) and a hose with a second valve.

Turbine problems 1.4Turbo (A14NET / LUJ)

The turbine of a GM 1.4-liter engine doesn't die on its own. Its resource can be greatly reduced due to the described problems with the crankcase ventilation system. Incipient lubrication problems and possible back pressure in the exhaust manifold negatively affect the operating conditions of the shaft support bearings.

The manufacturer admitted one specific malfunction of the turbine of the 1.4 Turbo engine (A14NET / LUJ). The problem is that the return spring of the actuator that controls the internal bypass valve of the turbine weakens over time and does not function well. Because of this, more and more exhaust gases slip past the turbine wheel in medium and high load modes, designed to spin the turbine impeller. The response of the motor and its power as a whole decreases, "error" P0299 (low turbine pressure) may be recorded.

The actuator, according to the manufacturer's idea, cannot be replaced separately. However, there are already proposals for non-original actuators. But its installation must be entrusted to specialists, since it requires adjustment and a special approach to mounting the actuator stem to the valve.

Destruction of engine pistons 1.4Turbo (A14NET / LUJ)

The saddest and most common problem with a small GM turbo engine is the destruction of its pistons, the baffle between the compression rings.

The problem is known from cars used in America and in the CIS countries. Most often found on cars produced in 2010-2013. The pistons can be destroyed both with a run of 20,000 km and with a run far beyond 100,000 km.

The manufacturer does not report the exact reasons for the destruction of the pistons, but it is not difficult to determine them:

• destruction of pistons occurs due to detonation, which occurs when using low-quality fuel. This reason also covers "chip-driven" engines, where, due to the increased pressure in the combustion chambers, detonation can also occur when operating on a fairly high-quality fuel;
• malfunction of the crankcase ventilation system, causing incorrect mixture formation (mixture too lean).

The destruction of the pistons of the 1.4 Turbo engine (A14NET / LUJ) occurs due to detonation that occurs when operating on low-quality low-octane fuel or with the wrong composition air-fuel mixtures.

Where to buy the 1.4 Turbo contract engine (A14NET / LUJ)?

The Opel / Chevrolet / GM 1.4 Turbo (A14NET / LUJ) engine can be purchased from the warehouse of Ravto.by, which has its own site in North America. In the USA, Ravto.by independently disassembles cars for parts and sends the parts to warehouses in Minsk and Moscow. For every detail and, even more so, for the motor, Ravto.by saves and transmits to the client information about the real mileage passed.

What is very important when buying an engine or automatic transmission, the mileage on power units and transmissions from the USA is an order of magnitude less than on European ones. In addition, engines removed from American cars have a minimum number of hours due to less stressful and free of traffic jams. The Ravto.by site is located in the southern United States and dismantles cars from this warm and not densely populated region.

Opel Astra of the fourth generation (with the J index) debuted in 2009. Its attractive lines make it stand out sharply from its dull predecessors. First-hand cars are rare. Among the cars imported from the West, the dominant ones are those restored after an accident.

Undercarriage

In addition to the beautiful "body", Astra IV received a number of new technical solutions. An example is the suspension design. In the front there are the time-tested McPherson struts, and in the back there is a regular beam or a Watt mechanism, supplemented by a system of levers. The latter can significantly improve behavior on the road, but significantly increases the cost of repairs. Some owners of vehicles with innovative rear suspension complain about loud performance, especially on short side joints and bumps.

Sport versions can be equipped with FlexRide adaptive dampers. However, their service life is shorter than that of conventional shock absorbers.

Massive lower wishbones allow you to change the silent blocks separately. But the ball joint is updated only with the lever. It saves that all elements of the lever are durable.

The interior remains in good condition for a long time. Opel is characterized by a large number of buttons and switches. There are almost 50 of them on the center console and steering wheel alone.

Another example of technical innovation is the electric parking brake. Fortunately (in terms of operating costs), this solution is only offered as an option (in expensive trim levels such as the Cosmo).

The parking brake mechanism quickly rusts with prolonged non-use (non-use) and in wet weather.

Rear brake calipers may clatter over time. Often it is possible to win the disease by stuffing grease into the caliper guides. There is also acidification of brake calipers. For repair it is necessary to disassemble and clean the mechanism.

Opel Astra J was offered with two options for power steering - electromechanical and hydraulic. You can determine the type of amplifier by opening the hood. In the presence of EUR, there is no reservoir and amplifier pump. In the presence of power steering, there is a reservoir and a pump located on the left side of the engine.

Engines

The high cost of used Asters, forcing most buyers to look for cheaper options with modest engines. Due to the relatively large weight of the Opel Astra IV (130 kg heavier than the Opel Astra III), the base 1.4-liter gasoline engine with a capacity of 100 hp. - far from the best choice. He has to work hard, and therefore consumes a lot of fuel - up to 11 l / 100 km. Ultimately, this will affect the resource. The most optimal, in terms of operating and maintenance costs, is the 1.6-liter 16-valve aspirated A16XER.

Both motors are quite reliable and durable. The timing belt of the 1.4-liter aspirated is driven by a chain, and the 1.6-liter is driven by a toothed belt. In the base 1.4, ignition coils sometimes fail. The reason is corrosion inside the rod. Vibration accompanies malfunctions. It is important that in the event of malfunctions in the ignition system, when the engine is running on fewer cylinders, the destruction of the catalytic converter does not occur.

The larger 1.6 uses a phase regulator mounted on the intake and exhaust camshafts. Sometimes he starts making noise. The first, as a rule, is the intake camshaft phase regulator.

1.6-liter petrol engine with 115 hp. there are not enough stars from the sky. But at least it doesn’t cause problems.

Turbo engines with a working volume of 1.4 and 1.6 liters have promising characteristics. Even the 120-horsepower 1.4 Turbo handles the Astra with confidence, thanks to its good elasticity.

1.4 Turbo has a fatal defect - piston cracking. The problem occurs in the 50-100 thous.

The problem with the Opel Astra 1.4 turbo engine

km. At the same time, the engine stops pulling and starts consuming a large amount of oil. The larger 1.6 Turbo doesn't show such weakness.

Diesel versions were not officially supplied to Russia. The choice of such specimens must be approached carefully. They are all equipped with a particulate filter. Most preferred is the 2.0 CDTI turbodiesel - the successful successor to the 1.9 CDTI. Such cars are very rare, and besides, they are very expensive.

Opel Astra with 1.7 CDTI is much cheaper. Average fuel consumption is in the range of 5.5-7.5 liters per 100 km. For everyday travel, this advanced Isuzu unit is sufficient. Only occasionally does the differential pressure sensor of the particulate filter or the EGR valve fail.

1.6 CDTi appeared in 2014. It uses a Denso injection system. Malfunctions are rare here, but at the same time, some owners had to change the turbocharger under warranty.

Incorrectly seated window seals at speeds exceeding 100 km / h cause loud aerodynamic wind noise.

The headlights often fog up, and a software error causes the automatic headlight range control to malfunction.

When working quickly with the lever, reverse gear may be engaged instead of the first. Elimination of the defect implies re-adjustment of the gear selection mechanism and the installation of a new stage.

On Astrakh 2010-2011, the clutch pedal return spring breaks. Opel carried out a service campaign to eliminate the defect. In addition, the shaft bearings of the six-speed manual transmission M32 do not differ in durability.

Incorrect operation of the on-board electronics control module quickly discharges the battery if the dipped beam or dimensions are left on for a long time. Opel has finalized the software.

In vehicles with 2.0 CDTI (engine code A20DTH), injectors malfunction due to errors in the software of the engine control unit. Updating the software solved the problem.

The exhaust system is prone to premature corrosion.

engine power is limited by opel astra

Unfortunately, most of the popular golf class sedans look pretty unlucky. The trunk is as if hastily attached to the body. Fortunately, there are exceptions that, by their appearance, on the contrary, attract and encourage choice.

Most car manufacturers create models that are similar to each other, regardless of class and price category. Therefore, it is sometimes even difficult for inexperienced motorists to immediately determine what kind of car is in front of him. Fortunately, Opel went the other way. Therefore, the Opel Astra Sedan cannot be confused with the big Insignia. In reality, Astra is much prettier than its older brother. Elegant lines, tasteful rims and an interesting brown with a golden sheen make the car feel like a prestigious sedan.

Jokes aside, the Opel Astra Sedan does look pretty. There is nothing to complain about here, every detail is well thought out. Even the optional spoiler on the boot lid looks elegant. This is one of the most beautiful sedans currently produced.

While simple and elegant design delights, there is one significant drawback inside - ergonomics. The plethora of buttons on the center console is a headache. There are a few buttons that I could not remember even after a week of close communication with the car.

A million buttons is one thing, but there is also something else - the control of the on-board computer. In order to confirm the correctness of the choice of the function, it is necessary to press not in the usual place - the center of the large round button, but to press the chrome ring surrounding it.

Malfunction in Opel Astra

This solution, although unusual, is to some extent not devoid of logic. This reduces the likelihood of accidentally pressing the button.

There are no complaints about the front panel. The attention to detail is very encouraging. The elegant steering wheel fits nicely in the hand and the instruments are easy to read. When sport mode is activated, the instrument illumination color changes from white to fiery red. The knobs and gear lever have the same illumination, which looks very nice at night.

The interior of the test Opel Astra Sedan was enriched with lovely brown leather seats that matched brilliantly with chocolate-colored plastic and light-colored leather trim on the dashboard and door panels. Bentley will envy this design, and it is by no means ironic. Of course, the quality of the materials is much worse here, and some of the plastic creaks. And even in spite of this, the interior still makes a very pleasant impression. In addition, the front seats and steering wheel are heated. A comfortable stay is ensured by dual-zone climate control and an electric sunroof.

When it comes to the level of vehicle equipment, it becomes obvious that the manufacturer did not spare the equipment for this instance. Navigation, Bluetooth, CD / MP3 radio is just the beginning. The Astra Sedan has rain and light sensors, automatic daytime running lights, a Line Asistant traffic sign recognition and lane keeping system. In addition, Opel was equipped with very good cruise control, which does not deactivate after pressing the clutch pedal, as is often the case. The on-board computer tells you the right moment to change gears. Indeed, it is astounding how many gadgets can now be ordered for such a small and not very prestigious car like the Opel. And this is really great!

There is enough space in the cabin, although there could be a little more, especially in the second row. Passengers taller than 185 cm will feel some discomfort due to the tightly hanging roof overhead. The stock of legroom is not so much, but you can hold out for a while until a person more than 190 cm tall sits down in front.

Of course, for every sedan, the volume of the trunk is considered important: 460 liters is a very good result. However, there is a small drawback. The trunk lid has rather large hinges that do not hide anywhere and can contact with luggage. The trunk can only be opened using a key or a button in the passenger compartment.

Under the hood of our Opel Astra Sedan is a 1.4-liter engine that, thanks to a turbocharger, produces 140 hp. and 200 Nm of torque. It would seem that so much power for a car of this class is too much. But this is not the case. Firstly, Opel cars have been suffering from the disease of the twenty-first century - overweight for many years. So the sedan weighs 1490 kg, while direct competitors are much lighter: Volkswagen Jetta with a similar engine - by almost 130 kg, and Ford Focus - by almost 200 kg. Therefore, despite the good performance of the engine, there is no excess in power. The sport mode improves the situation a little: reactions to the gas pedal become livelier, but overall the car remains sluggish. The technical specifications speak for themselves. Acceleration to 100 km / h takes 10.2 seconds.

For those hungry for more in the line of engines, a more powerful 1.6-liter unit is in store, which develops 180 hp with the help of a turbocharger. But something suggests that this will not be enough either ...

Fuel consumption is not sensational. On the highway, the recorded minimum is 6 liters per 100 km, and in the city it is not less than 7-8 liters. On crowded streets and intersections with traffic lights, ECO mode, which is nothing more than a Start / Stop system, helps save fuel. Her work is controversial. The engine stalls before the car comes to a complete stop, which is annoying especially in a slow-moving traffic jam.

The sedan is equipped with an adaptive suspension FlexRide with the ability to adjust the stiffness of the buttons SPORT and TOUR. In normal mode, the Opel Astra Sedan is very comfortable. And this despite the 18-inch wheels. Every unevenness is stoically swallowed, and silence and tranquility reign in the cabin. Sedan turns are also not scary. After activating the sport mode, the suspension becomes stiffer, but there is no huge difference. The steering is slightly worse. The steering wheel is too light. But in this case, the SPORT mode almost completely solves the problem - the steering wheel is poured with a pleasant effort. When you press the TOUR button, the suspension is supposedly softer and is ideal for not too twisty roads. But again, there isn't much of a difference.

Due to the large trunk, you need to be careful when maneuvering backwards. The view through the rear glass is not very good. Parking sensors solve the problem, and who does not believe in them, let him order a rear-view camera.

The Opel Astra Sedan is a real sedan, not a hatchback with a rear-riveted trunk. In addition, he is one of the most beautiful representatives of his class. The delightful design is accompanied by good workmanship. The only serious drawback is overweight, which, we hope, in the next generation of Astra will completely get rid of.

Automatic transmission device 6T40 cars Opel Astra J

Opel Astra J cars are equipped with a six-speed automatic transmission 6T40, which provides the choice of the optimal gearshift mode for almost any driving style and road conditions.

The 6T40 automatic transmission is configured according to the traditional planetary scheme with clutch braking and is connected to the engine crankshaft through a torque converter.

A feature of the automatic transmission Opel Astra J is the ability to switch from a fully automatic control mode to a semi-automatic mode, in which the driver, depending on driving conditions, can forcibly block automatic switching to higher gears.

The automatic transmission control drive is cabled. Lever 7 (Fig. 150) of the transmission control selector is installed in the same place on the floor tunnel as the manual transmission control lever.

The selector lever is connected to the lever 11 of the control unit on the gearbox with a cable 4. The differential is completely similar in design to the differential of a manual gearbox.

Diagnostics of the automatic transmission Opel Astra J

For an earlier and more accurate determination of a malfunction, there are several operations and verification tests. However, we strongly recommend that you do not abuse them and observe safety measures to avoid damage.

If the results of the test on the car are in doubt, you should consult a specialist for advice. The simplest is the time lag test.

When the engine is idling, when the drive mode select lever is set to "D" or "R" from neutral, there must be a time delay before triggering is felt. The purpose of this test is to check the performance of the gearbox assemblies and mechanisms.

For safety reasons and to prevent breakdowns of the 6T40 automatic transmission of the Opel Astra J:

- Before the test, warm up the box well, the temperature of the automatic transmission should be at least 50-80 "C;

- to achieve a high quality check, it is necessary to carry out at least three measurements and determine their average value;

- to preserve the high performance of the automatic transmission, take one-minute breaks between measurements.

The time delay test for the automatic transmission Opel Astra J is carried out as follows:

Raise the parking brake lever fully. Start up the engine.

Check the engine idle speed in the "N" range. The engine idling speed should be 750-900 rpm. If the idle speed of the engine does not correspond to the norm, then the measurement results will also be incorrect and the test will have to be repeated.

Move the drive mode select lever from the "N" range to the "D" range. Use a stopwatch to measure the time from the start of the handle movement to the moment of triggering.

Using the same method, measure when switching from the "N" range to the "R" range. In this case, the time delay should not exceed 1.5 s.

When evaluating the results of the test carried out, you should proceed from the fact that in the presence of any breakdown, the response time can only increase.

Only a professional can find out the cause and eliminate the malfunction, so you need to urgently contact the appropriate service center.

Quite simple and stand test.

Its purpose is to test the performance of the engine, torque converter and transmission as a whole.

To ensure safety and prevent breakdowns of the automatic transmission Opel Astra J:

- it is necessary to carry out the test in a sufficiently bright and wide area.

- two masters, working in pairs, must conduct the test: one of them must observe the wheels and their stops and immediately warn about the wheels turning or moving the stops, the second must carry out tests and record measurements;

- the duration of the test should not be more than 5 s.

Conducting the test and evaluating its results:

Be sure to secure the front and rear wheels.

Install a tachometer if necessary.

Apply the parking brake.

Press the brake pedal with your left foot and hold it in this position throughout the test.

Start up the engine.

Set the drive mode select lever to "D" range.

Pressing the gas pedal with your right foot until it stops, fix the tachometer readings. Take a break for at least one minute.

Repeat the test by setting the Opel Astra J automatic transmission mode selection lever to the "R" range. When evaluating this test, you need to know that each time you press the gas pedal, the tachometer needle should rise and stop smoothly in the interval of 2400-2700 rpm.

In this case, any extraneous noise, vibration and shock should not occur, and the car should remain in place.

If the tachometer readings:

- less than the rating, but the same in both ranges, then most often the reason lies in the insufficient engine power;

- higher than the rating in both ranges, then, most likely, the reason lies in a malfunction of the torque converter or gearbox;

- higher than the nominal value in one of the ranges, it is most likely that the fault is only in the automatic transmission.

The most difficult to conduct and evaluate a road test, which is carried out to determine the shift points, detect extraneous noise, vibration and slip in the automatic gearbox Opel Astra J.

To ensure safety, the test should be carried out on a sufficiently wide, level and empty section of the road; Warm up the engine and gearbox well before driving.

Carrying out a "road test" of the automatic transmission Opel Astra J and its assessment

Set the driving mode selection lever to the “D” position and, gradually pressing the accelerator pedal, check the presence of gear changes in I-II, II-III, III-IV and IV-V gears.

If there is no shift, then the automatic transmission or control and monitoring unit is faulty; if the switching points are too long, then the problem is most likely in the control system.

Fix the speed of 70 km / h in the "D" mode and slightly press the accelerator pedal. The engine speed should not change dramatically. If a sharp jump in engine speed is observed on the tachometer, then it can be argued that the torque converter is faulty, and it will soon completely fail.

Stop and move the Opel Astra J automatic transmission mode selection lever into the manual gear shift range.

Gradually pressing the gas pedal, check the presence of switching 1st. While in second gear, release the accelerator pedal and pay attention to engine braking.

Opel astra j

After repeating this operation several times, make sure that the switches I II and II I are not accompanied by vibration, shock or slippage. If there are no negative phenomena, then the box is in good condition.

Stop completely and, by moving the lever to position "1" and smoothly pressing the gas pedal, make sure that there is no switching to the second stage, and also check the presence of engine braking when the gas pedal is released.

When repeatedly pressing and releasing the gas pedal, listen to the operation of the 6T40 automatic transmission of the Opel Astra J to identify extraneous noise and vibrations. If there is a switch to the second stage or there is no engine braking, then the control and monitoring unit is faulty.

Stop and, having switched to the "R" range, sharply press the gas pedal. After making sure that there are no slippages, vibrations and extraneous noise, continue testing.

Having parked the car on an incline with a slope of about 5 °, move the drive mode selection lever to the "P" position and release the brake. The car must lock in place, if the car rolls down, then the reason should be sought in a malfunction of the box parking mechanism.

We remind you that during the test, you need to pay special attention to the presence of extraneous noise and vibrations. You need to treat them with due responsibility, since these noises and vibrations can be caused by an imbalance in the torque converter, drive shaft, etc., which can lead to unit breakdown.

Checking the level and topping up of the working fluid in the automatic transmission Opel Astra J

Periodically (but not less than every 15,000 km) check the level of the working fluid in the automatic transmission Opel Astra J. The design of the transmission does not provide for changing the working fluid during the entire service life of the vehicle.

However, sometimes the need to replace the working fluid may arise, for example, when the quality of the working fluid in the gearbox deteriorates after it overheats, etc.

Changing the working fluid in an automatic transmission requires certain skills, so contact a specialized service for a complete replacement of the working fluid.

For the automatic transmission Opel Astra J, the manufacturer recommends working fluid GM 93740313 or DEXRON VI.

Start the engine and warm up the transmission. The temperature of the liquid in the box should be 70-80 "C. To speed up the warm-up, you can make a short trip on the car. Usually, at an ambient temperature of 20 ° C, it is enough to make a 10-minute ride in a quiet driving mode.

Park the vehicle on a level, level surface. Apply the parking brake. With the engine idling, press the brake pedal and move the selector lever from "P" to "D".

Keeping the brake pedal depressed, let the car run for 1-2 minutes in the "D" position, then turn the selector for 3-4 seconds sequentially into each of the operating modes and set it to the "P" or "N" position. The engine must be running during the test.

The ingress of even a small amount of mechanical impurities into the working fluid of the box is unacceptable, therefore, before removing the liquid level indicator (dipstick), carefully wipe the surface around the meter tube from dirt.

The liquid level should be between the upper and lower limits of the "HOT" scale on the dipstick.

If the level check is forcibly carried out in a cold gearbox, use the scale on the dipstick.

The range between the marks is of a recommendatory nature and should not be used to accurately determine the level of the working fluid in the automatic transmission Opel Astra J. At the first opportunity, repeat the check in accordance with the recommendations.

If the fluid level is close to or below the bottom of the "HOT" scale, add fluid. The working fluid is topped up through the tube of the level meter in small portions. Add only the working fluid recommended by the manufacturer.

After adding fluid, be sure to check the fluid level again. Do not exceed the maximum permissible level, as this can lead to the failure of the 6T40 automatic transmission.

Opel Astra J. Engine interruptions

In case of interruptions, the engine idles unstably, does not develop sufficient power, and consumes more gasoline. In addition, the failure of the exhaust gas converters is possible. Interruptions, as a rule, are explained by a malfunction of the injectors or the electric fuel pump (see. Engine management system), malfunction of the spark plug of one of the cylinders, air leaks into one of the cylinders. It is necessary to find the malfunction and, if possible, eliminate it.

1. Start the engine and let it idle. Walk up to the exhaust pipe and listen for the sound of the exhaust. You can bring your hand to the cut of the exhaust pipe - this way interruptions are felt better. The sound should be smooth, "soft", of the same tone. Pops from the exhaust pipe at regular intervals indicate that one cylinder is not working due to the failure of the spark plug, the absence of a spark on it, the failure of the nozzle, a strong leakage of air into one cylinder or a significant decrease in compression in it. Pops at irregular intervals are caused by dirty injector nozzles, excessive wear or dirty spark plugs. If pops occur at irregular intervals, you can try to replace the entire set of candles yourself, regardless of the mileage and appearance, but it is better to do this after contacting a car service for diagnostics and repair of the engine management system.

2. If the popping is irregular, stop the engine and open the hood. Check if the harness connector is securely connected to the ignition module ...

3.… and tightening the two screws securing the module.

4. If the wiring harness block is securely connected and the module fixing screws are tightened, remove the module (see. Removal and installation of the ignition module).

5. Remove the spark plugs (see. Replacement and maintenance of spark plugs), carefully examine the candles and compare their appearance with the photographs given in the next subsection. Diagnostics of the engine condition by the appearance of the spark plugs... If the candle is black and damp, you can throw it away.

6. If all plugs look good, install them in the ignition module tips, and screw the spare plugs into the plug holes of the block head.

7. Connect the harness connector to the ignition module.

8. Connect one by one the bodies of the candles, for example, with a wire for starting the engine from an external power source to the "ground" of the car (for example, to a wire connected to the negative terminal of the storage battery). Ask an assistant to crank the engine crankshaft with the starter.

WARNINGS

Reliable contact of the spark plug body with ground is required, since if an additional spark gap appears larger than the gap between the spark plug electrodes, the engine control unit or the high-voltage circuit of the ignition module may be damaged.

Carry out the specified check no more than five seconds, so as not to damage the exhaust gas catalytic converter during the next start-up by gasoline that has not burned out in the engine cylinders.

Not so long ago on mine. An unpleasant error came out, or rather there were two of them, 84 and 89, and the ABS badge was also hysterically burning. I put pressure on the gas, but the car doesn't really drive, it barely develops speed, the engine does not want to spin more than 2000 rpm at all. LITTLE SHOCK! Immediately I thought, if the ABS caught fire, it means that the matter is in it, climbed to the forums, but the brake system has absolutely nothing to do with it! Errors appear on three cars - this is Chevrolet Aveo, Cruz, and also Opel Astra J - concern one "GM" the engines are almost the same, and therefore the problems. I'll make a reservation right away, I solved the problem, but I had to go for a drive and look for an intelligent diagnostician ...

The more complicated the situation, and the fact that now "GM" has left Russia because of the sanctions, so there are no officials left in our city (although there used to be two large ones). What to do? They write scary things on the forums that it is mainly a problem with the throttle valve. And this is already creeping into big money! Guys, for a general understanding, I will use a few not my own photos, but from open sources!

But first, about the mistakes.

Errorscode 84 and 89

ON Chevrolet AVEO and CRUZ, they are manifested precisely - code 84 and 89 + is on ABS .

But on the Opel Astra J is shown code 84 + it is written that the engine power is reduced + is on ESP .

Now a little transcript

84 - Reduced engine power.

89 - It is required to pass the next MOT (vehicle maintenance)

The Astra may be slightly different, but the essence is the same, why the ABS sensors still light up, ESP is not very clear. Apparently the car shows with all its kind - that it is time for her to the service station. Reduced power means that "emergency mode" is on, supposedly only to get to the service station and be repaired, so you should not wait for the "speed" from the car.

The car can - both triple, so start every other time, the speed floats, or how not to go with me.

What is the reason for the errors?

There are a lot of reasons, but it is worth noting that they are not always critical, so you should not buy spare parts right away!

Guys, I want to warn you - before you sound the alarm, you first need to look for an intelligent diagnostician and only then draw conclusions! After all, it wasn’t a matter of the throttle at all. But it turned out later.

Exactly a sensible one with a good scanner, who understands your Chevrolet or Opel, because if you connect a cheap scanner like ELM 327, then it simply may not detect the error!

SO, what problems can there be, I'll start with the most innocuous one:

• Underfilling coolant ... Trite - YES? But for a couple of people, after replenishing antifreeze, the mistakes were gone. I associate this with the fact that coolant pipes pass through the throttle, you can see if air begins to show there, this causes an error. So I did, my level was really small, but it did not help me!

• Dirty throttle ... From high mileage or from "shitty" fuel, after a certain mileage, the throttle is specifically "clogged". The position of the damper differs from the normal one (different angle), the ECU sees it, and it is visible, therefore errors 84 and 89 occur. It is enough to clean the damper and everything can be restored! But again it didn't help me!

• Heavy artillery begins ... This can be said to be a flaw in GM. The thing is that the throttle valve, like on many modern cars, is electronic. If you remove it (and this is still an event), remove the side cover (of the control unit), you can see 4 tracks and 4 contacts that go along them. So it turns out that contact 4, which is closer to the center, breaks or, as many write, is simply erased (although this can manifest itself both with a mileage of 5000 and 100,000 km, you can still see a flaw). This contact, as it were, "hovers" over the track, that is, it does not touch it, and this error appears! There is a solution here - carefully, preferably with tweezers, we bend the contact onto the track so that a connection occurs, in 80% of cases it helps and 84 - 89 leave. However, some did not help, they have to order a new choke. The fact is that the contact is complex, as it were, it does not consist of 1 metal element, but, as it were, of many metal "hairs". As I understand it, if not all are pressed onto the track, then the error will not go away. And it is really difficult to do it, the work is almost jewelry. Therefore, my diagnostician told me that it is possible to try to do it, but this is really not a panacea, anyway, after a certain period of time, it will need to be changed. The cost at once I want to say is considerable, the Chevrolet Aveo has an original throttle assembly from 13,800 rubles. For Chevrolet Cruze and Opel Astra J, prices can range from 15,000 to 21,000 rubles! Quite a lot! But I got carried away, it's not about the throttle!

• Gas pedal. Almost the same situation as with the throttle. Only cheaper. The gas pedal also has the same block and 4 tracks with 4 contacts. As you probably understood - contact 4 breaks, only at the pedal. Again, you can bend - restore, but you can also replace it immediately with a new pedal. Fortunately, the cost for the Chevrolet Aveo - Cruz is about 3000 rubles, for the original. But the Opel Astra - about 4000 - 5000 rubles. But again, this reason is not mine.

Probably intrigued. To be honest, the diagnostician fought over the car for almost a day. But I found the problem.

Cheap solution, my fault

I deliberately did not combine it with the first four, I want to dwell on my problem in more detail. Another warning - before we get into the brains and electronics, we throw off the battery terminals!

In general, I had a diagnostician "from God", as they say on Chevrolet and Opel "ate a dog", even worked for the officials for a year, then the current was cut (GM left Russia). He has a professional scanner, worth 160,000 "our wooden" ones, and every year he updates the firmware on it (about $ 300 - 400 more) - the balalaika is not cheap. Here is a photo.

But as he says, all the latest changes and information on new car models immediately appear (not only GM, all cars from our TAZOV, ending with Infiniti). Not one ELM 327 (from China) has such information even more so! Who will "cover" the annual firmware? That is why many Chinese scanner have errors - DOES NOT READ!

Diagnostics - he connected his "miracle device" and he gave out that this is not a choke! Wow, I just fell a stone from my soul, gave out - that this is a pedal! YES hell would be with her, buy a new one for only 3000 rubles, and replace it myself for a couple of minutes, unscrew one bolt, remove - connect the loop.

However, the diagnostician told me - let's try to restore this one, if the error goes away then 100% of the pedal, and then you decide - buy a new one or drive this one for a while. Okay, agreed. But to begin with, he says - I will measure all the chains - with a multimeter, I did not delve further, but it turned out that the pedal does not give any breaks! Unclear! It turns out she's whole ?!

He tells me this - he recently came to me on the Astra, code 84 + ESP also burned, as a result, the contact on the ECU oxidized, cleaned it, and everything worked like a clock. Let's take a look at your place. The 6 Volt load comes from there.

As a result, they oxidized to "green oxide", in my opinion from 42 to 46 contacts. When they were dismantled as much ofigeli, it is a pity that the photo was not left. We cleaned it, put it in its place and lo and behold, code 84 - 89 disappeared, ABS went out, the car began to breathe deeply! Damn, but under the hood and cold, and heat, and condensation in the fall. Here you can see them and ate up.

In the end, I didn't have to buy anything! Repair cost + diagnostics 1500 rubles - SATISFIED LIKE AN ELEPHANT! The master noticed - that the voltage on the contacts of the ECU is only about 3 - 5 Volts, (there are many of them), therefore - DO NOT USE ANY LIQUIDS TO IMPROVE CONTACTS, such as terminal protection, etc. So you can drop the voltage and just burn the ECU! You just need cleaning, it is advisable not to damage the protective coating of the contact (wipe with alcohol - carefully), then we blow everything with compressed air.
