Disadvantages of the Audi BDX engine
- The most famous problem with such engines is the formation of scuffing in the cylinders.
- The cause of scuffing is most often a faulty pouring nozzle.
- In second place here is the stretching of the timing chains and the failure of their tensioners.
- Phase regulators and ignition coils have a relatively modest resource.
- Many owners have experienced oil burner or soot on intake valves.
