Engine Overview and Common Failures

The weight of the VK45DD engine is 235 kg (without accessories). The engine number VK45DD is located at the junction of the block and the gearbox. The fuel system can be temperamental. This power unit is equipped with a temperamental direct injection fuel system called NEO DI, which does not tolerate low-quality gasoline: injectors fail and the fuel pump wears out. Scuffing and excessive oil consumption are common issues. Owners of cars with this engine often experience scuffing in the cylinders due to the ingress of wear products from the fuel injection pump lifter, as well as catalyst crumbs. Timing chain stretching is also a concern. Under normal conditions, timing chains serve up to 250,000 km without any problems, but with aggressive driving and sudden starts, the lifespan of the chains is reduced by about half. Engine overheating is another important issue to watch out for. It is highly recommended to regularly clean the radiators of the cooling system, as overheating can cause blown gaskets or even damage the cylinder head. Other problems include lambda sensor failures and clogged fuel pump filters due to poor fuel quality. Additionally, many users on dedicated forums complain about difficult winter starts. And don't forget to adjust the valve clearances, as there are no hydraulic lifters in this engine.
