Disadvantages, breakdowns and problems of the N55
This unit does not tolerate non-original oil and instantly cokes
Hydraulic lifters, Vanos and Valvetronic systems are among the first to suffer from coke.
In these internal combustion engines, the direct fuel injection system has become more reliable, but there are still a lot of failures.
Many owners change fuel injectors and injection pumps at a mileage of less than 100 km
The main culprit for oil loss here is the crankcase ventilation valve
