Disadvantages of the Audi CDHB engine
The owner of a car with such an engine spends their entire life battling oil consumption.
The manufacturer has made a number of piston options available, and changing them frequently is beneficial.
The motor’s interior is rapidly covered in soot as a result of the continuous oil fumes.
Purchasing forged pistons is one way to solve the oil burner issue.
Additionally, there is a very short-lived timing chain that occasionally spans 100,000 kilometers.
Injection pumps, water pumps, and ignition coils are not the best resources.
