It vibrates whilst stationary especially more at 1500 revs. I can’t believe it is a characteristic of the vehicle how can so many owners live with it? If I known it is common I would of bought a Renault Trafic half the price and no vibration issues. Not sure what to do as VW NOT INTERESTED.No?
Tracking or wheel balancing may need looking at.
Maybe start by swapping the front and rear wheels, ie front to back.
Any more details? All revs? What speed? Can you drive through it? Under braking?
Get them to demonstrate the vibration in an identical van at the dealership. When they can’t, get them to fix yours.
