I contacted Wimbledon Automatics re diagnosing my Passat DSG gearbox issue of vibration on the change up. Derek asked me to bring it down so he could road test the vehicle for an assessment. After a drive around he came to the conclusion it was one of two things, the clutch pack or the mechatronix unit. He was willing to do the job but advised the cost would exceed the value of the vehicle so didn’t make economic sense. It’s refreshing to be given an honest opinion as opposed to just taking my money so I have to give kudos to Wimbledon Automatics for that. Rest assured I will deal with them if I have auto gearbox issues in future.
