07 years of A4 1.8T. Cold start is not sound, after a few minutes to normal temperature will appear abnormal sound, especially when on the road uphill. The throttle speed will be a strong metal came "crashed" knocking at 1800 to 2200 (window to hear), very annoying. Go to the garage to the handbrake tension half clutch throttle to 2000 rpm, the master said to be in the engine sound, estimated to be reason for oil pump, please master can analyze is not the case. Thanks a million.
Derek, you said, this may be due to the replacement of the clutch three piece set, the right bridge vehicle problems caused by the phenomenon of failure, so I suggest you go to the 4S shop to remove the right wheel axle to check the cause of the failure.
The oil shortage caused by the oil pump jam is insufficient
Hello, this is the sound of the oil pump chain, so hurry up and repair it. Thank you
