hi hope you can help? i own a audi 07 s3 i just wanted to ask when your engine is worm and running on the spot do you get a little tapping noise? like a very fast clock ticking nois? audi are saying there all like this but i dont belive it? if you stand 5 meters away from your car is more clear to hear? when its cold there is no ticking noise so engine must be worm. sounds like a diesel thanks for your help.
