Never again for servicing. Decided since my DTM is full Audi history to keep it up until today. Thought at almost 100k and having done other maintenance myself, I'd take on the servicing. Well what can I say, the oil is never 9k old nor was the filter. Had to get my 4ft breaker bar on to the filter housing which was staring to look like it was going to snap. Sump plug took the same bar so if they were done recently they were way over tightened. I'd hazard that neither have been off in a long time. Suspect they have been doing the long life top ups rather than the full changes I asked for and was charged for. Check you're getting what you pay for if you use this lot.
