Disadvantages of the Audi CDNB engine
The majority of the owners’ grievances regarding this engine are related to its excessive oil usage.
Replacing the pistons is the most common way to solve this issue.
Decarbonization is occasionally required here because oil fumes create carbon deposits.
The timing chain can extend up to 100,000 kilometers, but its resources are limited.
Additionally, high pressure fuel pumps, water pumps with thermostats, and ignition coils are not useful in this situation for very long.
