My 2017 RS7 has been having intermittent transmission issues for months. Took it to two different shops, both claimed they knew Audis, neither fixed it. Finally found a small garage where the lead technician is a former dealer master tech who does manufacturer-trained Audi repair Dubai on the side. The guy knew my car's transmission better than I know my own phone. He pulled up specific technical service bulletins from his internal network, diagnosed a known issue with the mechatronic pressure accumulator, and fixed it in one day. The dealer had quoted me 15k for a whole new unit. He charged me 3k. I cannot stress enough how much of a difference it makes to have someone who has been through the actual factory training. He knew exactly where to look and what the real fix was. If you can find a former dealer tech who's gone independent, grab them and never let go. Anyone else had this experience?
