Disadvantages of the Audi AAH engine
Oil consumption is the primary complaint of car owners with such an engine.
After 150,000 kilometers, oil consumption due to rings starts, and it rises with mileage.
Additionally, grease tends to leak from seals and gaskets, particularly after overheating.
The valves always bend when the timing belt breaks because it is made to last roughly 90,000 kilometers.
Contamination of the idle control valve is typically the cause of floating revolutions.
