First off, why would anyone go to the dealership for routine maintenance considering how much it costs there. Also most maintenance can be done by the owner, including the DSG tranny, it is easy. The first time cost for the Vagcom cable tranny oil, filter, and fill hose setup, is about what VW charges for the tranny service. I have always done mine but due to being shutdown for maintenance at work very busy, so had an independent shop service the tranny for $325.00 vs the dealer wanting over $500.00. So yes it can be expensive, but I saved almost $200.00 by not going to the dealer.
