If you think, your Volkswagen has a serious defect that affects the safety of the vehicle, report it to the Volkswagen Dealer immediately. If you’re not happy with how the Volkswagen Dealer is dealing with your report, in the UK you should contact the Driver and Vehicle Standards Agency (DVSA).
But before that, you can describe the fault of your Volkswagen in our forum. Maybe some other VW owner will learn that he experienced the same issue. Multiple occurrences of identical defects mean a better chance of success in a complaint filed with the DVSA. Our website is visited by Volkswagen owners from all over the world.
