Disadvantages of the Audi CDUD engine
- The most frequent engine breakdowns are associated with the vagaries of the CR system with piezo injectors;
- In second place in terms of mass are problems with the particulate filter and the EGR valve;
- Regularly on the profile forum they complain about oil and coolant leaks;
- For runs over 250,000 km, they can already stretch out and require replacement of the timing chain;
- On diesel engines of the first years of production, sometimes there were defective intake manifolds.
