hi there...ive a scirocco diesel 170, its now done 8000k miles, just had its first service and ive noticed a vibration at and around 1300 revs, does it more when its warming up or been left for say 3/4 hr from hot, start the car, then hold the revs at 1300 and its vibrates, sounds like the engine dept, passenger side..
Had the car into the dealers, and have found the intake/airbox unit and pipework to be vibrating, found it quite quickly to be the problem, the car has to go in for 2 hour visit to be sorted.
I did wounder if this has been a problem on other cars as the mechanic quicky found the problem.
hope it gets sorted...
