Disadvantages of the Audi APG engine
Owners rarely worry about a straightforward and dependable power unit.
The throttle or injector contamination is the cause of the floating engine speed.
Additionally, the intake manifold’s vacuum regulator flaps occasionally stick.
Lambda probes, a mass air flow sensor, and a coolant temperature sensor are the most common electrical failures in this situation.
Numerous issues can arise from an erratic crankcase ventilation system.
