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.
* Addition: there are cases of bending the valves after the belt skipped half a turn. More details in the comments. - After 250,000 km of run, piston rings often lie down and an oil burn begins.

There needs to be a correction in the disadvantages.
I have the AQY engine in my Golf MK4 and the timing belt skipped half a turn last week. There was 0 compression on cylinder 4 and 3 and bit enough on 1 and 2.
After taking off the cylinder head we discovered, that the pistons had hit the valves and bend them.
It would be nice if you could make the correction, that the valves do bend if the timing belt brakes.
Thanks for your experience Paul, we have updated the engine information.
