JAMES,
Sounds like your mechanic DID NOT SET UP THE COMPUTER. you must set the computer with the vag 1551 or use a vag com. that will take care of the rough running. as for the loudness and vibration I will not comment on that as my motor is smooth and quiet but I have heard different stories.
this motor and ecu must be set with a computer to run properly.
