Mercedes-Benz C-Class Turbodiesel engines (W204) are sufficiently reliable units. Usually up to 200,000. There are practically no problems with them. At the same time, the engines are characterized by certain problems:
After 80 thousand The km of the mileage is recommended to replace the gaskets of fuel injectors. If this is not done, diesel-filled diesel fuel breaks down into the hot head of the unit, which may result in a nozzle. As a result, the nozzle becomes impossible to remove from the HC without breaking it and carving in the cylinder head.
On the late replacement of air filter (less than every 8,000. km), it is possible to get the oil in the intercull and further into the intake manifold. At the same time, the agility of the races is impaired and the engine starts to react to the brake pedal of the gas.
After 100,000. It is possible to wedge a gluteus lobe of the generator that threatens to break the belt.
