Disadvantages of the VW AQY engine
- This is a simple and reliable engine that worries owners only about trifles.
- The main problems of this motor are associated with failures of the components of the ignition system.
- Also, the electrician is often buggy: the idle speed controller or the crankshaft position sensor usually fails.
- The timing belt resource is approximately 90 thousand km, but when it breaks, the valves do not bend.
- After 250,000 km of run, piston rings often lie down and an oil burn begins.
