Disadvantages of the Audi APG engine
- A simple and reliable power unit rarely worries its owners.
- The culprit of the floating engine speed is the contamination of the injectors or throttle.
- Also, the vacuum regulator of the intake manifold flaps intermittently sticks.
- In terms of electrics, lambda probes, a coolant temperature sensor, and a mass air flow sensor most often fail here.
- A capricious crankcase ventilation system can throw a lot of problems.
