Disadvantages, breakdowns and problems of CDNB
Most of the owners' complaints about this engine relate to high oil consumption.
The most popular solution to this problem is to replace the pistons.
Carbon deposits form from oil fumes, so decarbonization is periodically needed here.
The timing chain has a limited resource and can stretch up to 100 km
Also, ignition coils, a water pump with a thermostat, high pressure fuel pump do not serve here for long.
