Disadvantages of the Audi CDHA engine
High oil consumption is this turbo engine’s most well-known issue.
The manufacturer has made a number of piston options available, and replacing them frequently helps;
The engine starts to overheat as a result of the oil burner, and the valves are soon covered in soot;
Here, the timing chain is a limited resource that can reach up to 150,000 kilometers;
The unit’s water pump, high pressure fuel pump, and ignition coils are also weak points.
