Disadvantages, breakdowns and problems of BDW
The main complaints about this unit are somehow related to seizures in the cylinders.
Another problem is the stretching of the timing chains and the breakdown of their tensioners.
Phase regulators and ignition coils are not the most reliable.
Often the dampers in the intake turn sour, and the entire manifold has to be changed
After 100 km, lubricant consumption often appears due to wear of rings and caps
