The French sedan based on Megane began to be produced in 2004 in Romania under the Dacia brand in order to meet the needs of the not-so-wealthy segments of the population of Europe and Asia. But, despite the poor equipment and cheap finishing materials, there were more than enough people who wanted to buy a reliable and durable car for relatively little money. Therefore, it was decided to organize the release of Logan in Russia, plus a hatchback appeared under its own name Dacia, as well as an MCV station wagon, a VAN cargo van and a pickup truck, which is called Pick-Up.

The budget of Renault Logan also lies in the fact that an affordable and simple design allows it to be repaired in any garage without spending money on service centers and installing expensive anti-theft systems, since the hijackers are absolutely not interested in it. Taxi drivers fell in love with the Logan for its large ground clearance, which allows forcing curbs and a smooth ride, especially since the build quality was excellent. The salon is very spacious, practical and quite comfortable, only all kinds of squeaks annoy. The level of practicality is reduced by the non-folding rear seat and very easily soiled upholstery, and there is no need to talk about comfort, since there is not even a cabin filter, the budget is the budget.

Operation and malfunctions of Renault Logan engines

Of the engines on the Renault Logan, the 1.4 l K7J with a capacity of 75 hp is most often found. and 1.6 l K7M in 87 hp. Both are simple, reliable and absolutely hassle-free, they work with pleasure on the A-92, and the service life of the gas pump is 200 thousand km. Replacement, however, is quite expensive, since it changes only in the collection.

The more powerful K7M is also quite high-torque and economical, the fuel consumption does not exceed 7 liters on the highway and 10 liters in the city per 100 kilometers. But it also has unpleasant features. Firstly, the throttle unit does not differ in durability, the resource of which rarely exceeds 70 thousand km of run, and secondly, to replace the timing belt, it is necessary to hang the engine and remove the support, which translates into additional costs. In addition, spark plug wells are not protected from dirt and when replacing spark plugs, all debris strives to get into the cylinders. To avoid this, it is strongly recommended to put felt rings on the candle tips. And when replacing the candles themselves, you need to be very careful, since the collector screen is all with burrs and it will not be difficult to get hurt. I would also attribute the lack of a fuel filter on them since 2008 to the disadvantages of gasoline engines, based on the quality of our fuel, this decision is rather controversial.

Engine oil is changed every 15 thousand kilometers, naturally with a filter. If, after 40 thousand km, a hum appeared on a cold start, then most likely this is due to the tension roller of the poly V-belt, usually with the engine warming up, the extraneous hum disappears. Replacing the timing belt is provided after 60 thousand km of run, and after 70 thousand km, a leak in the crankshaft oil seal may occur. Cars manufactured in 2007 often had a cold start problem, which is due to the engine ECU. In such cases, only the flashing of the "brains" helps. Even on the Romanian Logan, you will have to constantly monitor the rear engine mount, which is not distinguished by its durability.

Renault Logan transmission problems

The transmission on the Renault Logan is not original, since the gearbox and clutch are taken from, but this did not affect the reliability and durability. Only the fuzzy gear shifting of the five-speed manual transmission and the grinding noise when trying to engage reverse gear without stopping the car completely can upset. Some people forget that there is no synchronizer on it. The adhesion resource is about 80 thousand kilometers, which is relatively good.

You shouldn't mess with an automatic gearbox, it's very problematic and unreliable. Although its resource reaches 200 thousand km, before that, after a run of 80 thousand km, a breakdown of the hydraulic valve block and wear of the clutches is quite likely.

Disadvantages and sores of electrical equipment Renault Logan

Electrical equipment is also not happy, mainly due to the weak protection of harnesses, connectors and wiring. Special attention should be paid to the electrician when washing the car, since the not entirely successful arrangement of electrical appliances allows water to fill in the electronic components, sensors and ignition coils. In particular, the heater control unit and the engine ECU are located near the battery, so the likelihood of ECU failure increases with each wash. Many Logan owners are upset by the inconvenient access to the headlights, which is why they have to remove the battery to replace the lamps. The odometer is shamelessly lying, it shows 1000 km, although the car actually covered 925 - 930 km. The window regulator keys are very inconveniently located, since the designers decided to place them on the center console, what is the point here is not clear. After 30 thousand km of run, the cover of the fuse box located at the end of the panel looses and begins to creak. To eliminate the squeak, it is enough to put the durit hose on the pin of the steel frame. With the same mileage, you will have to replace the spark plugs and headlight bulbs, which, as a rule, burn out the dipped beam. A short-lived ignition coil requires constant monitoring, and the license plate lamp usually burns out after 40 thousand kilometers.

Steering Renault Logan

The steering of Renault Logan came from, so it is reliable and problem-free, just that the steering column was too high, and there are no adjustments. The steering tips change after 100 thousand km of run, but the steering rods are not so durable, they will have to be replaced much earlier.

Malfunctions in the running, suspension and braking system Renault Logan

In the braking system, the most short-lived are the front brake pads, the resource of which rarely exceeds 30 thousand km, the rear drum brake pads can withstand up to 100 thousand km of vehicle operation. Brake discs can withstand three pad changes, and the caliper guides will require constant monitoring, regular lubrication is extremely necessary for them. The suspension is generally comfortable, energy-intensive and hassle-free, providing a smooth ride. The front one came from, therefore it is quite durable, and the back one is also reliable. First of all, after 60 thousand km, the bushings and stabilizer struts will need to be replaced; behind them, in the region of 110 thousand km, the shock absorbers' resource will end. Ball joints work out the longest, they will have to be changed after 120 thousand km of run, but the replacement will upset with financial waste, since they are pressed into the levers and change only with them. In the chassis, only the wheel bearings turned out to be short-lived, the rest of the parts were problem-free.

Sores and problems on the body Renault Logan

The body will please with a large trunk and cheap body parts, but the paintwork turned out to be weak, especially in the area of ​​the windshield frame. Most often, paint swells here on cars manufactured before 2006; on later releases of Logan, this defect was most likely eliminated. Many people will not like the large trunk hinges, which eat up a decent volume of the trunk, as well as the short-lived trunk lid locks. Corrosion resistance turned out to be rather low, especially for cars manufactured before 2008. First of all, the roof, the upper edges of the windshield and rear windows, gutters and rear wheel arches suffer, chips on which are instantly covered with rust. In addition, the windshield is overwritten very quickly. Particular attention should be paid to rugs, which tend to shrink from temperature changes and reagents, after which they stop holding on to the bosses and slide under the pedal assembly. The danger lies in the fact that the accelerator pedal starts to stick in the depressed position, with all the ensuing consequences. And finally, when reversing out of a snowdrift, check the front mudguards, whose inner caps simply break off during such maneuvering. It is best to put composite VAZ ones with a core fungus instead of the standard ones.

Good day gentlemen / comrades.

To begin with, we have had this car in the family for 4 years already, it was bought new in April 2012, it is operated by his father, and since his trips are short and there is still a second Niva car, the mileage at the moment is only a measly 25 thousand. kilometers, 5-7 of which my brother and I dashed off.

And we will actually talk about the first breakdown, and it is not so much serious as it is difficult to eliminate, thanks to the Romanian-French engineering thought.

Father calls, says something rattles, creaks from the generator, the first thing that came to mind was that it was a tension roller, because you don't expect something serious on such a run, father was told not to take a steam bath, go home and wait for the weekend, we'll come and see.

Then, after thinking, it was decided to go to the service, well, as a service, a garage) because my father lives in the village, and the nearest workshop is 20 km away in another village, or 40 km away in the town where I live. By the way, this service is not bad, the private trader works for himself, values ​​his reputation, at one time we even went to him from the city.

Well, they found the following, the generator pulley was unscrewed, and the nut was tightened, and the pulley dangled, it is not so easy to check it, you cannot crawl up and cannot be seen.

To tighten it, you need to remove the generator and here the fun begins, from which the father, as an elderly man and not used to such perversion, is still in shock.

1 It is necessary to remove all protection, but these are trifles;

2 Remove the wheel

3 Remove the BUMPER, yes yes, otherwise it will not crawl

4 Remove the power steering pump, well, or take it aside on the hoses, which is not easy to do (we did the second)

5 With the help of some Romanian mother, remove the generator through the interfering hoses of the gur and the air conditioner

This is the Kama Sutra.

I didn’t believe the master, I went online and yes, that’s right, if there is no gur and conder, then everything is easily removed, but here it’s like this.

The generator was removed, a washer was placed under the nut and the pulley was tightened, but it felt a little thrown over, maybe it seems, or maybe it led a little, they tried to find a new one, it's not realistic with us at all, or go 300 km in the region. center, or order in the store, thank God we can, but wait at least a week, in short, they have assembled so far, everything seems to be fine, maybe it just seems that it’s a little crooked.

Digging around all day ...

They paid 2500 for the work, I think the officials would have ripped off at least 10, and they would also drain the liquid from the power steering.

It is worth noting here that even for such a tarantula as Logan you cannot find spare parts in the outback, there is something for Daewoo (Lanos), Hyundai Accent and there is EVERYTHING on VAZ)))

I climbed onto the Loganovodov forum, it turns out that this is a disease, I did not know, but there are a lot of cases of unscrewing the generator pulleys, some even fell to the ground, mostly this happens on runs of about 50-60 thousand km, and almost does not manifest itself until the moment when it thunders or falls off.

The new original pulley costs 1200r, analogues from 400r.

A new generator, the original costs about 30,000t.r, apparently it is made of gold with platinum plating) substitutes from 6 thousand rubles.

The rest of the car is in good working order, it runs perfectly, we only went through TO 1, we won't chase it anymore, it makes no sense to pay from 8-10 thousand for changing the oil and filters.

These are the pies! Good luck to all!

Lost idle speed

To determine the causes of this malfunction, special diagnostic equipment is required, so in this case, contact a service station that specializes in repairing vehicles with injection engines.

Most often, this malfunction is caused by a failure of the idle speed control or air leaks through loose connections of the throttle body hoses.

If it was not possible to restore idle speed by replacing the regulator and tightening the hose clamps, contact a specialist.

Interruptions in engine operation

In case of interruptions, the engine idles unevenly, does not develop sufficient power, and consumes more gasoline.

Interruptions, as a rule, are explained by a malfunction of injectors or an electric petrol pump; spark plugs of one of the cylinders by sucking air into one of the cylinders. It is necessary to find the malfunction and, if possible, eliminate it.

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 suction 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.

If the popping is irregular, stop the engine and open the hood.

Check the condition of the ignition wiring harness and check the wiring harness on the ignition coils.

If there is damage to the wires, replace the entire ignition harness.

Remove the spark plugs. Take a close look at the candles and compare their appearance with the photographs shown in the article below.

If all plugs look good, reinstall the plugs and coils and connect the wiring harness pads to them.

Disconnect the harness connector from the 1st cylinder coil.

Start up the engine.

If the engine interruptions have not increased, replace the spark plug in the 1st cylinder with a known good one.

Put on the high voltage wire and start the engine.

If interruptions intensify, repeat the procedure sequentially with all cylinders in order to identify the faulty spark plug.

If, as a result of the measures taken, the engine interruptions are not eliminated, check the compression in each of the cylinders. Normal compression is more than 1.0 MPa (10 kgf / cm 2), the difference in compression values ​​in the cylinders of more than 0.2 MPa (2 kgf / cm 2) indicates the need for engine repair.

Diagnostics by the appearance of spark plugs

Normal candle

Brownish or greyish-yellowish color and slight wear on the electrodes.

Matching the heat value of the spark plug to the engine and operating conditions.

Soot deposition

Dry soot deposition indicates a rich mixture or late ignition.

Causes misfiring, difficult starting and erratic engine performance

Oily electrodes and spark plug insulator

The reason is the ingress of oil into the combustion chamber.

Oil enters the combustion chamber via valve guides or piston rings.

Causes difficult starting, cylinder skips and jerking of a running engine.

Make the necessary repairs to the cylinder head and piston group of the engine.

Replace spark plugs.

Deposition on the skirt of the insulator of iron oxides of a brownish-red color from anti-knock iron-containing additives (ferrocenes) to gasoline.

They are deposited in an even, dense layer.

When the engine is operated under heavy load with high temperature and pressure in the combustion chamber, oxides are converted into conductive paths of pure iron, which short-circuit the center electrode to ground.

This causes misfiring, a drop in engine power.

This could damage the catalytic converter.

Plaque is practically not removed mechanically and does not fade when moving at high speed.

If it is not possible to immediately replace with new candles, then place the candle in a rust converter, then clean the candle with a metal brush, rinse with water, and then with gasoline.

Fused electrodes

Early ignition. The insulator is white, but may be contaminated by misfiring sparks and deposits from the combustion chamber.

May cause engine damage.

It is necessary to check the correctness of the spark plug type, the cleanliness of the injector nozzles and the fuel filter, the operation of the cooling and lubrication system.

Cracked or chipped insulator

Damage caused by detonation.

May damage the piston.

Occurs when the knock sensor is malfunctioning.

Make sure the gasoline meets the requirements.

Mechanical damage to the candle

Damage can be caused by foreign objects trapped in the combustion chamber, and in the case of a plug with a long skirt, its electrodes can catch on the piston.

Remove the foreign object and replace the candle.

Surely every present or future car owner is interested in possible weaknesses and shortcomings of his present or future car. Therefore, this material is intended for those whose soul lies in such a car as the first generation Renault Sandero. Of course, at first glance, this car has an attractive design and price, but Sandero still has its weak points, illnesses and shortcomings, which need to be known not only for the present owner, but also for the future when buying.

* - the data are indicated depending on the configuration.

What are the advantages of Sandero I:

1. Fuel efficiency;
2. High reliability;
3. Unpretentiousness;
4. Maintainability;
5. Low cost of both the car itself and its spare parts;
6. Corrosion resistant;
7. High ground clearance;
8. Sturdy undercarriage.

Weaknesses 1st Generation Renault Sandero:

• Paintwork;
• Cooling system;
• Automatic transmission;
• Exhaust system;
• Power steering sensor;
• High voltage wires;

In this case, the paintwork certainly cannot be called a weak point of this car, but a factory defect. This is very common on the roof of a car in the form of pitting. But few people pay attention to this or simply don’t know. But this is a reason to bargain with the seller when buying this car. Perhaps he himself does not know about such defects in his car.

Of course, it is impossible and unnecessary to say that the entire system in this car is defective, from the radiator to the pipes, etc. The weak point in the cooling system is the thermostat. Most of the owners of these cars, already in the first years of operation, were faced with a failure of the thermostat, moreover, with low mileage.

This problem, as is already clear, often arises on cars with automatic transmission. And it is impossible to name specific weaknesses of the automatic transmission, namely, the entire box is weak and prone to overheating. Sometimes it happens that with a mileage of less than a hundred thousand, problems arose with the box due to overheating, and accordingly, if the car was under warranty, contact the officials, and if not, then invest in a round pretty penny. It can also be noted that there may be trouble with the automatic transmission control unit. This problem is felt in the movement of the car, namely, before shifting the 3rd or 4th gear. In this case, the engine speed is reset, and then vice versa and, accordingly, switching to a higher gear. And in general, it is worth noting that when buying any car, you need to make a test run and feel, listen, and see how the car behaves.

Exhaust system.

Why can the exhaust system be called a sore spot, because it is subject to corrosion and quickly rusts and decays. Of course, we can say that this "jamb" is found on most cars, but it is on this particular nuance that special attention is paid. Logically, this can only be explained by the quality of iron and poor anti-corrosion protection. In any case, when buying a used car, this moment cannot be ignored.

The crux of the problem is that very often the owners of Renault Sandero I are faced with such a phenomenon as liquid drips in the area of ​​this sensor. This happens due to the squeezing out of the sensor under pressure and, accordingly, the loss of fluid and the problem with the power steering as a whole. This is not a critical issue, but it is quite common.

High voltage wires.

In this case, high-voltage wires pose quite a few problems for car owners. The point is that on this car, high-voltage spark plug wires are of poor quality. And the most important thing is that this can be called not only a weak point, but even a factory defect. This affects primarily the behavior of the machine. The car begins to twitch while driving, and this in turn indicates that the high-voltage spark plug wires are piercing. This is mainly due to dampness. But again, you need to pay attention that this is due to the poor quality of high-voltage wires.

Steering column switch.

Many Sandero owners complain that after several years of active use, one or more signal wires on the directional switch breaks, making it impossible to turn on the turn signals. This issue can only be resolved by a complete replacement of the unit, or by re-soldering the wiring.

The main disadvantages of Renault Sandero 2007-2012 release:

• Many owners complain about fuel consumption higher than stated;
• When the air conditioner is turned on, the engine loses much power;
• Inconvenient location of the spare wheel, which greatly complicates its replacement;
• The mudguards are very poorly fixed from the factory, as a result of which they constantly strive to fall off;
• Low and high beam bulbs often burn out;
• The salon does not retain heat well;
• An uninformative clutch pedal, located in such a way that when you squeeze it you have to keep your foot on weight;
• Low level of safety in the event of an accident;
• The quality of the material. Hard plastic is easily scratched;
• Weak insulation. Although there are few cars with good noise insulation, it is necessary to mention this drawback;
• The windshield wipers on the Renault Sandero are also a disadvantage. The essence of this drawback is that the wipers are very short, and this affects the driver's visibility;
• Weak dynamics. This is not surprising, because these cars are not equipped with the most powerful engines;
• Fuel gauge. It is also a disadvantage due to its defectiveness. Quite often, there are moments with an incorrect display of the real amount of fuel;
• Simple interior design;
• Small trunk volume;
• The manual transmission is also a disadvantage, not a weak point, as many car owners have encountered knocks when changing gears. But this is not a sign of failure of the manual transmission, but a typical operation of the box.
• Ergonomic miscalculations. Every Sandero car owner will definitely find something not convenient for himself. And there is nothing in between;
• Crickets in the cabin and, in particular, the side windows.

Summarize.

In conclusion, we can say that each car has its own weaknesses and shortcomings. And, of course, Renault Sandero has more pluses than minuses, but the choice with which gearbox and engine to buy a car must be approached with a thorough analysis, weighing all the pros and cons. Also, do not expect unrivaled comfort and a high level of equipment from this car, because it belongs to the ultra budget class. Oddly enough, many forget about it and start hating a poor car for what in vain, not noticing its obvious advantages.
