Operation Mercedes-Benz E200 (W212). Disadvantages of cars and problem areas according to car owners. There will definitely be costs: we choose a Mercedes-Benz E-Class W212 with mileage

Mercedes-Benz Cars Group is a super-popular manufacturer of premium cars, part of the Daimler AG concern and the so-called big German three (together with Audi and BMW). The Mercedes brand itself is one of the most expensive and recognizable in the world. In addition, famous cars such as the Mercedes-Benz 300SL, better known as the “Gull Wing”, the iconic Mercedes-Benz 600SEL (six hundredth), the sports Mercedes-Benz SLR McLaren, the ageless Mercedes-Benz G-Class SUV drove out of the gates of the Stuttgart company. Gelandewagen and a number of popular and well-known cars.
Considering all of the above, such a powerful automaker as Mercedes is simply obliged to produce reliable engines, but you will find out how things really are with this below, in the list of models.
Mercedes engines are a huge range of powertrains such as in-line 4-cylinder, five and six-cylinder, both in-line and V-shaped configurations. In addition, V8 and V12 engines were produced for the top and most powerful Mercedes-Benz cars. In addition to atmospheric versions, supercharged engines were produced: with a compressor, turbine and twin-turbo. For sports versions of Mercedes-Benz, the AMG division developed powerful versions of engines,

predominantly V8 and V12. In addition, along with this widest range of power units, Mercedes diesel engines of all possible configurations, any displacement and power were also produced and continue to be produced.
Now you do not need to look for a variety of reviews, all types, markings, types and models of Mercedes engines are already here: new and old, gasoline and diesel, aspirated and compressor, conventional and AMG.
Having chosen your model, you will get acquainted with the following information: what engines are put on a Mercedes, their technical characteristics, description, problems, malfunctions (stalls, knocking, troit, etc.) and repairs, numbers, resource, etc.
At the same time, there is information on what kind of oil to pour into a Mercedes engine, how much oil is required and how often it needs to be changed. In addition to this, attention is paid to tuning the Mercedes engine, how to increase power without losing a resource for urban use, and so on.
After reviewing the information available, you can easily decide which Mercedes engine is the most reliable, and who needs to replace the engine, you can easily decide which contract engine is worth buying.

A new generation of Mercedes engines with innovative technology.

Innovative? How can you call gasoline and diesel engines innovative? Many environmentalists, experts and other participants in the car market are probably perplexed. But this is true. Mercedes has unveiled new engines with innovative technologies for the updated S-Class, which will be produced from 2017.

Weird? But what about electric motors, about which, probably, everything that is possible has already been said. Indeed, according to experts' forecasts and according to the plans of a number of leading countries of the world, the days of internal combustion engines are numbered. Partly it is. But there is one but. In the coming years, a mass market for electric cars is not expected.

It will likely take decades for electric vehicles to displace ICE vehicles from the market. And this is regardless of the fact that the authorities of Western countries want to get rid of vehicles running on internal combustion engines in the near future. As much as it would not be desirable for many developed countries, but until the popularity of electric vehicles overshadows gasoline and diesel cars, we will not see the decline of vehicles running on traditional internal combustion engines.

All new Mercedes engines are coated with a friction-reducing compound.

That is why Mercedes continues to develop new gasoline and diesel engines for its future models.

As a result, Mercedes introduced five new internal combustion engines that will be installed in S-class cars from 2017.

Petrol engines 1.6, 1.8, 2.0 M 111 / M 271.

Short description.

- 4-cylinder;

- 16-valve;

- multi-point injection / direct;

- compressor or turbocharger.

Mercedes has been rather cautious about supercharging gasoline engines. The Germans relied on a compressor instead of a turbine in order to provide a smoother increase in power without the unpleasant effect of "turbo lag". The result was presented in 1995 in the face of the M 111 motor with a mechanical compressor driven by a conventional ribbed belt. Seven years later, its more modern version, M 271, was shown.

The most widespread is the 1.8-liter version of the M 271 with a multi-point injection system with varying degrees of forcing: from 122 to 192 hp. In some models, a modification with direct fuel injection was used. It was produced between 2003 and 2005 and developed 170 hp. It can be recognized by the CGI markings.

The desire to reduce capacity led to the creation in 2008 of the 1.6-liter M 271 with a compressor. Its use was limited to the C-class W204 and the not very successful CLC. The engine did not have direct injection.

The latest version of the 1.8-liter M 271 with direct injection received a turbocharger instead of a compressor. This engine developed from 156 to 204 hp.

Compressor wear.

For a long time, no one undertook to restore the compressor, offering only to change it. Fortunately, today mechanics have mastered the technology of its regeneration. The cost of such a service is about 100-120 dollars, including dismantling and installation. The most common compressor failure is rotor bearing wear as well as clutch failure.

If an annoying howl is emitted while the engine is running, then it's time to intervene. But be careful: exactly the same sound is made by worn generator bearings. You can buy a used compressor from a scrapyard for about $300, repairing a clutch costs about $500, and a brand new unit will cost $1,500. Unfortunately, the compressor life is short - just over 100,000 km.

Timing chain jump.

Timing chain wear, unfortunately, is asymptomatic. She can jump over already after 60-80 thousand km. It is a pity that a weak single-row chain is used to drive the timing, fortunately its replacement is not too expensive - about $ 250. The fault applies only to M 271 motors.

Oil leakage from the valve timing regulator.

A typical malfunction of the older generation of M 111 engines. Oil begins to drain from the electromagnets, damaging the electrical harness. Effective elimination of a defect is a time-consuming task and, worst of all, not always feasible.

The use of engines 1.6-1.8 K / T (M 111, M 271).

These motors were used only in Mercedes cars. They were always located longitudinally in front. All motors were assembled at only one factory in Germany.

Mercedes CLC: 05.2008-06.2011;

Mercedes SLK R170: 09.1996-04.2004.

Conclusion.

If you decide on a Mercedes with a compressor, then be sure to choose a newer version of the M 271 and be prepared to invest in replacing the chain from the very beginning. The advantages of the 1.8 K engine are low fuel consumption. It is better to stay away from older versions of the M 111. Alternatively, you can opt for the naturally aspirated 2.0 16V or later 2.4 V6.

New Mercedes diesel engines with four and six cylinders

To Code designation for the new Mercedes four and six-cylinder diesel engines: OM 656

Naturally, all the new Mercedes engines of 2017 have become even more economical and more powerful than their predecessors. True, in order to achieve these technical results, engineers used completely different technologies in the development of power units.

A new generation of Mercedes engines appeared on the Mercedes E-class - the E200 D model.

In fact, a new generation of Mercedes engines began to be introduced in the spring of 2016, when the German brand introduced a new two-liter diesel engine for the E-class. This engine consumes 13 percent less fuel than the previous similar power unit. The increase in the efficiency of the diesel engine was achieved due to the lower weight of the power unit, the reconfiguration of the engine control unit software, and also by reducing friction in the cylinders, thanks to the new special Nano Slide coating.

The new six-cylinder engine for the S-class, designated under the index OM 656, is, in fact, an enlarged version of the four-cylinder engine for the E-class, which was introduced in early 2016.

The all-new six-cylinder Mercedes diesel engine, which will be installed in the S-Class from 2017, has a power of 313 hp. Recall that a similar engine of the previous generation produced only 258 hp.

The 2017 Mercedes six-cylinder diesel engine is based on the OM 656 four-cylinder engine, which is installed on the E200 d of the new W213

This engine uses the same monobloc emission control technology found in the four-cylinder powertrains found in the 2.0-liter four-cylinder diesel E-Class.

For example, in a six-cylinder diesel engine, Mercedes engineers installed the CAMTRONIC system, which was previously used only on small power units. This system reduces intake valve opening time at low engine speeds, resulting in significant fuel savings.

Diesel engine 200-220CDI-OM 611.

Short description.

- 4-cylinder;

- 16-valve;

- common rail injection system;

- turbocharger;

- for cars of the middle class and above, vans.

In 1997, a major change took place in the history of Mercedes diesel engines: for the first time, a common rail direct injection engine was used. It was used in the first generation Mercedes C-Class station wagon. At the same time, the designation CDI appeared, which is still used today.

The engine was marked OM 611. It has 4 cylinders and a working volume of 2.2 liters. The first samples developed 125 hp. and 300 Nm of torque. Compared to its predecessor OM 604, the new unit received an increase in power by 30%, torque - by 100%, and fuel consumption fell by 10%. The injection system operates at a maximum pressure of 1350 bar. Initially, the engines were equipped with a fixed geometry turbocharger, and since 1999 a supercharger with an adjustable position of the turbine blades has been used. The volume was also slightly reduced from 2151 to 2148 cm3. The gas distribution system is driven by a chain, there are two shafts in the head, there are four valves for each cylinder.

The OM 611 engine family has several different modifications. In passenger cars (C and E-Class), a unit labeled 200 CDI (102-115 hp) and 220 CDI (124-143 hp) was used. In addition, there are variations with 82 and 102 hp. for Vito, Viano and Sprinter vans, 122 hp - for Vito and Viano, and 129 hp for Sprinter.

In 2002, with the debut of the E-Class W211 series, the new generation 4-cylinder engine OM 646 and its derivatives, the 2.7-liter OM 647 and 3.2-liter OM 648, were introduced. Despite the similar design, about 80% of the components new.

270/320 CDI (OM 612 /OM 613).

The next direction in the development of the OM 611 engine family was an increase in the number of cylinders. The 5-cylinder unit was designated OM 612, and the 6-cylinder unit was designated OM 613. The first, marked 270 CDI, developed from 156 to 170 hp, and the second, 320 CDI 197 hp. Mention should also be made of the 3.0-liter version of the 612 OM with 231 hp, designed for the C 30 CDI AMG.

Operation and typical malfunctions.

Mercedes diesel engines of the previous generation were famous for their incredible endurance. Due to the more complex design, sometimes there were problems with the OM 611. Just a larger number of elements had more chances to break. Fortunately, serious malfunctions did not occur too often. The cylinder-piston group has high strength. The turbine and dual-mass flywheel typically last several hundred thousand kilometers. It should be borne in mind that the mileage of the car in the ads for sale coincides with the real one only in exceptional cases. When choosing a car with CDI, it is necessary to be guided by an assessment of the technical condition of a particular instance.

Difficult start.

As a rule, it is associated with wear of the high pressure pump, less often with a malfunction of the injection system - injectors.

Intake manifold.

In many versions of the engine, dampers were installed in the intake system, the closing of which led to an increase in the turbulence of the air entering the cylinders, which improved the quality of its mixing with fuel. Malfunctions of this element lead to a noticeable decrease in engine power and a slow increase in speed.

Thermostat.

CDI engines warm up rather slowly. But if even after several tens of kilometers the motor does not reach the desired temperature, then the thermostat will have to be replaced.

Application of OM 611.

4-cylinder engines were used in class C and E cars, and in minibuses. 5 and 6 cylinders in larger models.

2017 Mercedes six-cylinder petrol engines

Mercedes' new gasoline engine now runs on new 48-volt power grid

Undoubtedly, the main attention of experts and those who are interested in new Mercedes engines should be focused on new gasoline engines. Particularly interesting is the V6 gasoline power unit M256, whose power will now be 408 hp. Torque over 500 Nm. This became possible thanks to the use of technologies that Mercedes previously used only on V8 gasoline engines.

Thanks to innovations, engineers have been able to reduce the fuel consumption of the new six-cylinder M256 engines by 15 percent compared to the previous power units installed in the Mercedes S 400 (333 hp).

Mercedes-Benz V8-Biturbo-Benzinmotor, M176 ;
Mercedes-Benz V8-biturbo engine, M176;

By the way, an electric motor with a power of 20 hp appeared in the new motor between the crankshaft and the gearbox.

In fact, this is an integrated unit, which is a generator and starter in one component (ISG). That is, when necessary, the electric motor works as a starter and helps the engine reach maximum torque at the very beginning of acceleration, which provides the car with maximum traction at low revs.

Also, this node can work as a generator, feeding a number of important vehicle equipment. The electric motor is powered by the energy generated during braking, which enters a special battery.

New diesel S-classes will consume less than 5 liters of fuel per 100 km

Each new Mercedes engine is distinguished by a variety of different technologies that have made power units more powerful and much more economical than their predecessors. On average, each engine has become 5-10 percent more economical and 5-15 percent more powerful.

The most efficient today is the 258 hp diesel engine currently installed in the Mercedes S350 d. So this model has an average fuel consumption of 5.3 l / 100 km. way.

The new six-cylinder diesel engine, which will be installed in the S-Class from 2017, will consume less than 5 liters per 100 km.

V8 Biturbo AMG Mercedes petrol engine with 476 hp

M 176 engine. New twin-turbo V8 petrol engine 4.0-liter 476 hp

The latest new engine that Mercedes is introducing is the powerful AMG Bi-Turbo V8 4.0-liter power unit with 476 hp. with a maximum torque of 700 Nm. Motor code M 176.

The new motor will replace the 4.8 liter V8 engine with 455 hp. Despite the increase in power, the new 4.0-liter V-8 engine will be 10 percent more fuel efficient than its 4.8-liter predecessor.

This was made possible thanks to CAMTRONIC technology (valve opening and closing optimization system), which is used in six-cylinder diesel engines. In addition, the new eight-cylinder engine uses a cylinder deactivation system (cylinders 2, 3, 5 and 8) to save fuel. This mode is only active in Comfort and Eco modes at 3250 rpm.

New engine 2017 Mercedes-Benz S-class under the symbol M256

If such an article had been written twenty or thirty years ago, its message would have been unambiguous - Mercedes power units may not be the most innovative, but there are hardly any more durable ones among competitors' engines.

Today, Mercedes engines use a large number of technical innovations designed to reduce harmful emissions and increase productivity while reducing fuel consumption. Unfortunately, this took a toll on legendary durability. And if nothing terrible is still happening to the engine block and head, then malfunctions of the injection system or supercharger have become something commonplace. Troubleshooting is usually expensive. It is gratifying that the company quickly learns from its mistakes and quickly overcomes them.

Gas engine V6 2.5-3.5 M 272

Short description.

V-shaped 6-cylinder;

24-valve;

Multi-point injection / direct;

For middle class cars and above, SUVs.

An aluminum V-6 with the code designation M 272 debuted in 2004. She became the successor to the M 112 V6, which has been used since 1998. The main changes are the use of the DOHC system (two camshafts in the head) and 4 valves per cylinder instead of 3. The design uses a number of modern solutions: an instant change in the valve timing of the intake and exhaust valves, an intake manifold of variable length (that is, there are dampers). In addition, a balancing shaft is used, which eliminates vibrations caused by a large camber angle of the block. As a rule, in V-shaped motors an angle of 60 degrees is used (i.e. a full shaft revolution divided by the number of cylinders), and in the M 272 engine it is equal to 90 degrees.

Most units of the M 272 family have multipoint injection into the intake manifold. In 2006, a version with direct fuel injection debuted. Initially, the engine with the new injection system went to the Mercedes CLS, and is currently used in the E-Class W212 with the designation CGI. In 2010, the successor to the M 276 was introduced, however, the M 272 series motors are still being produced today.

Operation and typical faults

The M 272 engine has only one characteristic malfunction. But its elimination is expensive, and the consequences are quite serious. Therefore, it is quite difficult to recommend the V-shaped six Mercedes.

Worn balance shaft teeth.

The defect is so widespread that in the US, owners of defective vehicles filed a lawsuit against the company in the USA, demanding free repair of broken M 272 engines. Wear on the teeth of the balance shaft gear accelerates chain wear and can cause it to skip. In addition, as a result of incorrect operation of the gas distribution system, a dangerous composition of the mixture in the cylinders is formed, which leads to the destruction of the catalyst. The fault affects all engines with serial numbers up to and including 2729…30 468993. Repair parts are not too expensive (about $250), but the procedure requires the removal of the engine, which will cost about $700-1000.

Conclusion

Only one, however, a serious defect casts a shadow on the reputation of the entire family of M 272 engines. Engines in which the defect with the balancing shaft has been eliminated are worthy of recommendations. The 5-liter V8 is famous for much greater reliability, although the average fuel consumption is 17 l / 100 km.

Diesel engine 200-250 CDI-OM 651

Short description.

4-cylinder;

16-valve;

common rail;

Turbo or biturbo boost.

In 2008, Mercedes introduced a new generation of turbodiesel with the designation OM 651. Initially, the unit had a working volume of 2.2 liters, and since 2011, a 1.8-liter unit has replenished the family. Both diesel engines have the same cylinder diameter, but the smaller one received a shorter piston stroke - 83 mm instead of 99 mm. The compression ratio in both versions is 16.2:1.

The engine debuted in its best form - 204 hp. It was installed on C-Class 250 CDI cars. The power unit had twin turbocharging and Delphi piezoelectric injectors. The same solution (biturbo and piezoelectric injectors) was applied a little later in a weaker 170-horsepower version of the 220 CDI. And if there were no special problems with supercharging, then the nozzles caused a lot of suffering. They were so serious that in 2011 the 220 CDI was modified, and since 2012 the 250 CDI received conventional electromagnetic nozzles.

Weaker versions (up to 200 CDI 143 hp) used less troublesome solenoid injectors from the start. In addition, these engines had a single variable geometry turbocharger.

The OM 651 has replaced a wide range of older generation 4, 5 and 6-cylinder longitudinal and transverse engines ranging from compacts to vans.

Operation and typical faults

A shadow on the reputation of OM 651 was cast by problems with piezo injectors. The scale of the defect was enormous. To eliminate defects during the warranty period, it was necessary to stop the current production of engines. It must be admitted that Mercedes conscientiously approached the issue of eliminating the problem. Motors with conventional injectors did not create such problems.

Piezoelectric nozzles.

This is a standard malfunction of the first years of production. The engine went into emergency mode while driving. There were cases of sudden stop of the motor. At present, the scale of the problem is small.

Valve train chain.

With increasing mileage, more and more facts are being recorded about problems with the timing chain. The replacement is troublesome - the chain is located at the rear of the engine.

Pump leak.

Another problem that is gaining momentum with increasing mileage and the age of cars.

Application of OM 651

The OM 651 engine has found wide applications ranging from compact models to limousines, sports cars and even vans.

Conclusion

Innovative in many ways, the engine created a lot of trouble for Mercedes. Malfunctions in the 220 and 250 CDI versions further undermined the brand's credibility. The simplified versions are more durable.

Epilogue

The legendary Mercedes engines in pursuit of power, low fuel consumption and environmental friendliness have lost their former reliability. The block itself with a cylinder-piston group is designed for at least 500,000 km, but auxiliary equipment fails much earlier, and repairs are very expensive.

28.12.2016

Mercedes E-class at any age is very popular, which, as a rule, only increases over the years. And this happens for a simple reason, the fact is that not everyone can afford a new Mercedes, but a car under the age of 5-7 years significantly loses in price, which makes it a very attractive option in the secondary market. The predecessor of our hero (W211) received a lot of criticism for a large number of failures and a small resource of the main units. But how things are with the reliability of a car in a newer body, and what to look for when buying, we will try to figure it out using the example of a used Mercedes E-class in the back of W212.

A bit of history:
This is the fourth generation of the German brand's E-class cars. For the first time, the car was presented to the public at the Detroit Auto Show in 2009, in the same year mass production of the model was launched. The appearance of the Mercedes W212 was worked out on a concept car, which debuted in 2008 at the motor show in Paris. In 2011, a minor modernization of the car was carried out, which was purely cosmetic in nature. In 2013, a deep restyling was carried out, which gave the car a more modern and sporty shape. Mercedes W212 is available in one of four body types - sedan, station wagon, coupe and convertible, also, a version from the sports division is on the market. "AMG" (E63 AMG, E63 AMG S). In 2016, sales of the fifth generation started on the market E-class in the back of W213.

Advantages and disadvantages of a used Mercedes W212

The quality of the paintwork and anti-corrosion coating is at a high level. Thanks to this, such minor troubles as chips do not often bother the owners, and there are no complaints about the body metal either. Corrosion on the car body can appear only after poor-quality restoration of the paintwork. But some body elements do not match the image of the car. So, in particular, due to poor sealing, the headlights fog up very much, which often leads to failure of the electronic headlight control unit.

Engines

Mercedes W212, depending on the type and size of the engine, has the index E200, E220, E250, E350, E300, E350 and E500. The following power units are offered at the buyer's choice: gasoline - 1.8 (184 and 204 hp), 2.0 (156 hp), 3.5 (252, 306 hp), 4.7 (408 hp); diesel - 2.2 (136, 170 and 204 hp), 3.0 (231 and 265 hp). The main problems of a 1.8 engine are associated with a small resource of the timing chain (a long single-row chain is used on the car, which is prone to stretching). The main sign of the need for an urgent replacement of the chain will be difficult starting of a cold engine and diesel rumble at idle. Also, you should pay attention to the condition of the oil filter. The fact is that, quite often, smudges appear on it, which lead to a significant decrease in the oil level in the engine.

As on the 1.8 engine, the 3.5 engine should constantly monitor the condition of the timing chain ( chain life does not exceed 100,000 km) and oil filter. Also, the common disadvantages of this power unit include a small resource of the gears of the balancing shaft and the destruction of the intake manifold dampers. The difficulty of diagnosing this problem without special equipment is that when it appears on the instrument panel, the indicator “ CheckEngine”, but many owners mistakenly think that the cause of the error is poor-quality fuel and, instead of contacting the service, continue to operate the car. On post-styling versions, the fragility of the chain tensioner is noted. Oil leaks are a common problem on most vehicles, especially around the turbocharger.

The 2.0 engine has proven to be the most reliable among gasoline engines, but it also has drawbacks - a change in the geometric parameters of the intake and exhaust manifold shafts. An unstable engine operation will serve as a signal that there is a problem. Diesel engines have also proven themselves well, not only in terms of reliability, but also efficiency ( average fuel consumption 6-7 liters per 100 km). The 2.2 engine of the first years of production is most often bothered by piezo injectors, a service campaign was even carried out on this occasion. The best option among diesel engines is a 3.0 engine, it has practically no drawbacks, plus it has a considerable resource (with proper maintenance, more than 500,000 km). If the diesel W212 was refueled with low-quality diesel fuel, then, soon, the particulate filter will need to be replaced, and this pleasure is not cheap. When buying a Mercedes W212 with a diesel engine, you need to be very careful, since in Europe very often cars of this model are operated by taxi services.

Transmission

Four transmissions are available for the Mercedes W212 - six-speed manual, five- and seven-speed automatic transmissions. After restyling in 2013, the car is equipped with a nine-speed automatic transmission. Most often, the owners are bothered by the frequent failure of the seven-speed automatic. This transmission is afraid of heavy loads and overheating, which occurs quite often, especially if the car is operated in a metropolis. To avoid possible problems with automatic transmissions, you need to constantly monitor the condition of the transmission cooling radiators. Also, there are complaints about the reliability of the electronic gearbox control board ( most of the time it will burn out.). If the board burns out, the transmission will automatically go into emergency mode. If there is a smell of burnt plastic in the cabin, pay attention to the condition of the box cooling system pipe, which is located behind the intercooler. Other gearboxes do not have significant drawbacks and, with proper operation, will last 200-250 thousand km without problems.

Features suspension Mercedes W212 with mileage

Mercedes W212 is equipped with an independent suspension: front and rear suspension - multi-link ( after restyling, a MacPherson strut suspension is installed in front). The system of adaptive shock absorbers was equipped on all production cars, but the pneumatic system " AIRmatic» was installed on the car optionally. Regardless of the modification, air bags are installed on all station wagons. The Mercedes W212 has a standard rear-wheel drive, and an all-wheel drive version of the car is also available on the market ( 4Matic). Most of the suspension parts are made of aluminum, which significantly increases the cost of its repair. The W212 chassis is famous for its excellent comfort and impeccable handling.

If we talk about the reliability of the suspension, then it does not like bad roads, but if you live in a region where the quality of the road surface is relatively good, then you will have to invest in its repair no more than once every 80-100 thousand km. Also, it should be noted the good quality of the materials from which the pneumocylinders are made and their considerable resource. The main disadvantage of adaptive shock absorbers is that if at least one of them fails, the car will be able to get to the service only with the help of a tow truck. The steering is quite reliable, for example, with careful operation, the steering rack will last 200-250 thousand km, steering tips and rods can last 100-120 thousand km. Brake pads take care of 30-50 thousand km, discs will last twice as long.

Salon

Traditionally for the German brand, the quality of finishing materials is at a high level, as a result, extraneous sounds do not bother the owners even after 5-6 years of operation. If you are planning to buy a car with a panoramic sunroof, be sure to check the condition of the guides. The fact is that in most cases they are clogged with dirt, which leads to incorrect operation of the electronics; also, in rainy weather, water can enter the cabin through the hatch. If we talk about the reliability of electrical equipment, then here we can highlight a couple of unpleasant features. In rare cases, the central lock, power windows and horn malfunction. Also, they may stop responding to pressing the button of the head unit, and the parking sensors at the most inopportune moment begin to play silent.

Outcome:

- a quality car, which, in most cases, pleases its owners with its reliability and comfort. But, do not forget that it has a lot of components and mechanisms with a limited service life, for the replacement of which, over time, you will have to pay a tidy sum, since the maintenance and repair of the Mercedes W212 is quite expensive.

Advantages:

High quality paint finish.
Build quality.
Large selection of power units.
Comfort suspension.

Flaws:

Small timing chain resource.
High maintenance cost.
A small resource of the automatic transmission.

The most popular pre-style motor is the compressor 1.8 M271 Evo, which was installed on the E200 and E250 in boosted 184 and 204 hp. The main problem is the small resource of the timing, chain, stars and tensioner. Often it ended even before 100 thousand, and before the chain jumped, a characteristic noise appeared on the cold and Check Engine. But not everyone was lucky.
- Another problem of the M271 is the leakage of the oil filter housing (cup) - it was originally made of plastic, and it cracked. In some cases, the replacement of the gasket helped, but the correct solution is to replace the housing.
- Also pay attention to whether the oil smells of gasoline and whether there is oil fogging in the area of \u200b\u200bthe control dipstick, otherwise, most likely, the life of the crankcase ventilation valve has expired.
- Post-restyled inline fours 2.0 turbocharged (E200 184 hp and E250 211 hp) - M274 series. In general, a good motor, but with a couple of weak points. The variable oil pump valve wiring fails due to constant heating and an aggressive environment, which is why the engine can run with oil starvation for some time until the “check” lights up.
- Part of the M274 engines suffered from antifreeze leaks into the oil through the pump (oil level above the maximum) and from critical wear of the camshafts (cracking when starting on a cold one). Both problems were fixed under warranty - just check by VIN whether the car was subject to recall or not.
- On older gasoline V6 3.5 M272 (E300 and E350 until 2011), the problem with the wear of the balance shaft gear and the subsequent timing disorder by the time the W212 was released is a thing of the past. Now the drive resource has increased steadily by 150-180 thousand. But the motor remained sensitive to maintenance. So, overheating, detonation from bad fuel, rare oil changes and dust from destroyed catalysts can finish off the aluminum coating of cylinders. Therefore, endoscopy is essential.
- When choosing a car with M272, pay attention to oil leaks, this time from under the oil heat exchanger - a family problem.
- Another characteristic misfortune of the M272 is the wear of the intake manifold flaps, which lasts 60-80 thousand, rarely more. If the collector has not changed and has not been repaired for a long time, then this is waiting for you in the near future.
- Motors V8 M273 (E500) - the same series as the V6 M272. Childhood illnesses have been resolved, certain problems remain, and for more or less successful operation, uncompromisingly high-quality service is needed.
- Gasoline V6 3.5 new generation (E300 and E350 after 2011) - M276 series. And here, too, children's problems are noticed. In particular, direct injection piezo injectors, as well as timing chain tensioners and dampers were changed under warranty (check VIN, whether it is subject to recall, consult the dealer). A characteristic symptom is chirping when starting on a cold one.
- The same applies to the V8 series M278 (late E500) unified with this engine.
- Diesel engines 2.1 (E200 CDI, E220 CDI, E250 CDI) of different forcing from 136 to 204 hp - OM651 series motors. Until 2011, they were haunted by the problem of the ultra-small resource of piezo injectors, which were changed under warranty, moreover, together with the control unit. After switching to electromagnetic, the motor annoyed only with typical diesel problems: EGR, a particulate filter, then after 150 thousand nozzles, after 200-250 - a turbine and high-pressure fuel pump, and at the same time the timing chain along with the stars.
- Diesels 3.0 (E300 CDI, E350 CDI) are V6 series OM642. There were no "early" problems with injectors here, everything is usually limited to typical diesel breakdowns described above.

Few people remember that the nameplate with the letter E, which later became the designation of a whole class of cars, and not only the Mercedes-Benz concern, but the entire European automobile industry, appeared for the first time in the spring of 1972 on a model with a body index 114. It testified that from now on, under the hood of the most powerful modification of the brand's mid-size sedan, a fuel-injected engine (Einspritz) appeared. The motor itself was a gift from the master's shoulder from the Mercedes-Benz 280 SE model.

Almost forty years have passed, and top-end engines still fall under the hood of the E-class from their older brother. This time - motors of the new generation BlueDIRECT, officially presented last spring (SR 2010, No. 7). Modernization was embodied in improving the efficiency of combustion, increasing efficiency and environmental friendliness. Now all E-class gasoline engines are equipped with direct injection and a start/stop system.

E-efficiency

The new "turbo-eight" of the flagship model E 500 growls in a bass voice, whistling relish the turbine at full throttle. The whole process of traction control is precisely measured injections of acceleration in exactly the dosages in which the driver wishes it. This motor makes you fully feel that there is no excess power for Mercedes: the chassis allows much more. However, in reality, it’s not even the dynamics that are striking, but the consumption: with a leisurely ride, a 400-horsepower express train easily fits into 8.5 l / 100 km.

E-economy

Model E 350 is the most anticipated among Russian fans of the E-class. Due to the optimal combination of characteristics, it rightfully accounts for the lion's share of sales. The pleasant baritone and decent dynamics of the six emphasize status and do not burden with frequent refueling: you can cover a couple of hundred kilometers on the autobahn in an hour with a moderate appetite of 13 l / 100 km, and if you don’t rush, then the consumption will completely approach the “diesel” values of 7– 8 l/100 km.

E-cology

The diesel E 250 CDI is the most environmentally friendly car in the entire E-Class range: CO emissions are 130-134 g/km. It is also the most economical in the class - 4.9–5.3 l / 100 km. This is the entry-level heavy fuel engine for the Russians. The engine starts: a tight set of speed from a vigorous bottom continues without a loss of acceleration characteristic of diesel engines up to a cutoff. Too bad it's noisy.

The E-class engine line is one of the richest, perhaps not only in the class, but also in the overall standings. It will soon be replenished with the first diesel hybrid E 300 BlueTEC Hybrid in the history of the Daimler concern, equipped with a 15-kilowatt electric motor. The total power of the power plant is 224 hp, the maximum torque is 600 Nm. According to the manufacturer, fuel consumption in the combined cycle will not exceed 4.4 l / 100 km, and CO2 emissions - 116 g / km. We are waiting for a response from competitors.
