Disadvantages of the Audi CDUD engine
The unpredictability of the CR system with piezo injectors is linked to the most common engine failures;
Issues with the EGR valve and particulate filter rank second in terms of mass;
They frequently complain about oil and coolant leaks on the profile forum; for runs longer than 250,000 km, the timing chain may already stretch out and need to be replaced;
There were occasionally faulty intake manifolds on diesel engines from the early years of production.
