I've had my Arteon from new for 5 weeks now. 10 days ago, the driver's door started buzzing/vibrating. It happens when I initially press the gas pedal or intermittently while on the move. My dilemma is whether to take it to the local VW dealer to get it fixed for free even though they have a poor rating or go to an independent specialist for a fee but with a high customer rating. Any suggestions?
