Right then guys im pretty pissed off !Ive missed the RR day @ awesome gti due to this, My 2000 X reg S3 is making a very worrying noise from the engine its a loud tapping noise and it seems to be coming from inside the rocker cover near the cam belt cover. It only happens @ about 1600-1800 RPM the car doesnt idle roughly there seems to be no power loss oil is ok and the noise doesnt dissapear with the clutch depressed. can some one please help me here and put my mind at rest. Am i looking at a big bill or is this something less serious ??
