Review

Mercedes took the W204 project very seriously. The Germans claimed to have tested the new car on public roads for three years, carried out more than 100 crash tests and covered millions of kilometers. All this was done not only to make Mercedes more comfortable and better riding, but also to finally stop breaking down. And let this is just an invention of marketers, but something out of the plan came out. The Mercedes C-Class, which debuted in 2007, is likely not to interest BMW fans. The car with a star is softer and more sedate. This is partly due to the standard Agillity Control system, which adapts the running gear to the road surface and speed. So, the suspension becomes assembled during high-speed driving and soft on the pavement. There are many other safety-enhancing systems here – smart headlights, Pre-Safe collision preparation system, 7 airbags (including a driver’s knee cushion), etc., etc. After restyling in 2011, the model received a number of assistance systems. The W204’s appearance remains conservative and overlaps with the larger S-Class W221 in its style. Despite the fact that the car, compared with its predecessor, has noticeably increased in size, there is still not enough space behind. However, it will feel mainly tall passengers, more than 180 centimeters tall. The average rating deserves and the width of the cabin. The sportier version of the Avantgarde has a powerful Mercedes star grilled, while other variations (Elegance and Classic) carry the brand logo on the hood.

Gasoline

The most common gasoline 4-cylinder units with a volume of 1.6 and 1.8 liters (M271). Both engines are trustworthy, but later modifications with a turbocharger are much preferable instead of a compressor. They are more economical and quieter than their predecessors. The second is especially important, since the rather noisy operation of the mechanical compressor makes it difficult to make the correct diagnosis - stretching the timing system chain. Unfortunately, this defect has become widespread, both in earlier and later modifications. Owner’s concerns should cause a strange noise within seconds of starting, uneven engine performance and a “Check” alarm. If you do not check and replace the timing drive (80-100 thousand rubles), then the gears of the camshafts (two 27 000 rubles each) can wear out, and then the chain will jump or even break (valves are damaged). In the latter case, you will have to look for a new engine (the cost of used is about 80-100 thousand rubles), since it may take up to 200 000 rubles to restore the old one. The defect manifests itself to 100,000 km, and it is recommended to monitor the state of the timing system drive every 50-60 thousand km. In addition, the engines of the M271 series at a segment of 50-100 thousand km are forced to face failure of the thermostat (from 9 000 rubles), pumps (from 14 000 rubles), valve ventilation crankcase gases (from 2 000 rubles) and flowing oil glass (10 000 rubles). In 2013, the M274 appeared with a turbocharged volume of 1.6 liters. The chain drive of the timing system was finalized here and there were no more general problems at small runs.

Diesel

There is no doubt that some customers are attracted to diesel modifications. This is not a bad choice, but you should be prepared for some features. Unlike the Sprinter, the 2.1-litre Mercedes C-Class turbo diesel doesn’t pose too many problems. In the early years, an old and simple version of the engine with Bosch nozzles was used (from 22 000 rubles). Its fuel system is resistant to low-quality diesel fuel and is durable. Later (from October 2008) was installed more complex in technical terms unit with the designation OM 651 – the chain of the timing system is located behind the engine (between the engine and the box). The timing system drive has a decent resource, but in the case of replacement, the work of the mechanic will be expensive. The real disaster for OM651 was the gentle Delphi nozzles (from 30,000 rubles). However, over time, this problem was eliminated. Sometimes troubles are delivered by the differential pressure sensor of the exhaust gases of the particulate filter (from 2 200 rubles). Another common problem is the failure of the water pump. However, the turbine (from 70 000 rubles) and two-mass flywheel (from 40 000 rubles) have a decent resource - more than 200 000 km. In the dual-charge versions, you will have trouble with the turbine control system. The complex design makes it difficult to make a correct diagnosis. One of the vulnerable elements of the OM 651 is the pump, especially until July 2009 (from 12,000 rubles). The diesel V6 OM 642 is not too bothering for its owners. However, sometimes premature wear of the liners occurs.

Transmission

The vast majority of Mercedes C-Class are equipped with automatic transmission - 5-speed, and since 2011 model year - 7-speed. With large runs, the electronic part of the automatic transmission often fails. For repairs along with spare parts will have to pay about 30 000 rubles.

The machine requires regular maintenance. Every 60,000 km, the oil, filter and gaskets (about 15,000 rubles) must be replaced. He will serve faithfully and faithfully for a long time. Otherwise, repairs will be needed to 150-200 thousand km (frictions, hydrotransformer and oil pump).

The manual transmission is much more reliable.

Walking

The chassis of the Mercedes C-Class, as a rule, does not cause serious trouble. The rear multi-link suspension allows you to change the silencing blocks separately from the levers. The front suspension requires more frequent intervention - already to 50-100 thousand km. Soon it is necessary to update the front and rear shock absorbers (4-9 thousand rubles). The scallop bearings will last a long time.

Other problems and malfunctions

The body of the Mercedes C-Class is now not subject to corrosion. The mastered kilometers and the past years do not leave a noticeable trace in the interior.

Failures in the electronics sometimes caused by the discharge of the rear battery. However, from time to time there are malfunctions of the ABR system - adaptive braking system. To eliminate it will have to spend - 20-25 thousand rubles.

On the pre-restyling W204 after 100-150 thousand km begins to mope the steering switch of light and direction indicators. It should be disassembled and cleaned well.

Many people have to deal with a failed steering blocker. In most cases, the fault of the motor - wear out the brushes. Repairs will cost 5,000 rubles, and a new unit in the collection is available for 28,000 rubles.

The generator is delivered after 150-200 thousand km. In the service for repairs will ask 6-8 thousand rubles. With age, the engine of the stove can whistle (5-10 thousand rubles).

Replacing the lamp in the back lamp is not a difficult procedure. A common problem is poor contact, and, as a result, melting of the electric connector (about 300 rubles). Sometimes you have to change the electric charge (3,000 rubles).

AMG is for the brave only.

The combination of a 6.2-liter petrol W-shaped “eight” and rear-axle drive fascinates Mercedes fans. The engine works in tandem with a 7-speed automatic. The AMG version was available in all three body variants: sedan, coupe and station wagon. The model is characterized by reinforced brakes, a denser and “cut” suspension, as well as redesigned steering. Everything is done here to get the maximum pleasure from driving.

Should you buy a Mercedes C-Class W204? Yes, but provided that we are talking about a copy with a proven history and the presence of some cash reserves. Paradoxically, it is cheaper to maintain versions with larger engines, as they have a higher safety margin. If you are looking for smaller engines, you should look after the cars after 2012. Rust can not be afraid, and its presence signals poor-quality body repairs in the past.
