Disadvantages of the Audi CDRA engine
Here, reducing fuel and oil quality frequently results in the creation of scores;
Because of the direct injection system, coking is a common cause of engine issues;
Timing chains can already stretch after about 200,000 kilometers, and replacing them is challenging and costly;
The plastic intake manifold frequently becomes loose and cracks;
The ignition coils and oil separator are two more areas where this motor is weak.
