8P S3 only on idle sounds like a diesel very tapperty and rattley etc, ain't coming from the engine to the best of my knowledge I think maybe from the Cambelt aera? Potentialy could be water pump or the cam belt the tensioner?
Cambelt was done 7K ago..
Car boosts more than fine and idle is smooth!
Just abit worried everytime I get out the car and hear the devil noise lol!
Whats your thoughts?!
Thanks in advance
