Hi all,

I am new in this forum.

I have a Polo GTi 6n2 with the AVY engine. The car starts to ping at low revs when I punch the throttle.

It has been serviced. The engine timing is correct, took it to the VW Agent. The injectors are not leaking (no smell of fuel where the injectors are) and no code fault.

Any ideas?

Most help appreciated.
