Disadvantages of the VW AAM engine
This engine is incredibly dependable in terms of iron, and when the belt breaks, it doesn’t even bend the valves.
Suction from a ripped single-injection cushion is the primary cause of the issues.
Here, the throttle position potentiometer frequently malfunctions as well.
The idle speed controller, sensors, and ignition system components all have limited resources.
Fuel consumption starts to rise dramatically when a lambda probe or its wiring burns out.
