Disadvantages of the Audi CDNB engine
- 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 100,000 km.
- Also, ignition coils, a water pump with a thermostat, high pressure fuel pump do not serve here for long.
