Disadvantages of the Audi BDX engine
The development of scuffing in the cylinders is the most well-known issue with these engines.
The most common cause of scuffing is a malfunctioning pouring nozzle.
The failure of their tensioners and the stretching of the timing chains come in second.
The resources of ignition coils and phase regulators are comparatively small.
Numerous owners have encountered soot on intake valves or oil burners.
