I thought I'd try this Audi Certified shop to assure top quality service. They were prompt in handling my repair but after paying a $940 bill, the core problem was right back. They said it would be hundreds more to fix it. At that point, I asked why they charged $95 diagnostic charge in addition to the parts and labor for the repair. Seemed like a relevant question since they obviously misdiagnosed the problem the first time and it took then 5 minutes to come back with the new diagnosis. I pointed out that most places, including dealerships, don't included that charge when you get the repair. I was told that never mind my past experience, and the many receipts I have that show no such charge, they actually do include that charge. Went back to my old neighborhood shop and they fixed the problem for $65.
