Never ever have service done here if your car is out of warranty. My Q7 with 77k miles needed the oil breather valve replaced for the 2nd time in 3 years. This is a $270 part that requires super charger removal to replace. Total bill $2,560. They screwed up and gave me the detailed itemized invoice they send Audi - $1,243, parts and labor. Audi Dominion charged me a $1,317 unexplainable mark up to install a $270 part. For what was really $2,000+ in labor charges Audi Dominion was able to finish my car in a day with 1 tech. Miracles do happen. To make me feel better the service manager told me that if I'd gone to another repair shop and had the work done for $1,200, they would not have used genuine Audi parts. You mean the $270 genuine Audi part that failed in 30k miles and cost me $2,500?!
Stay away from this dealership unless your car is under warranty. I had a similar issue with them last year with a $3,500 air suspension repair. Same genuine Audi part failed twice in a short period if time, but outside the 12 month warranty. Good thing I didn't see the Audi Dominion mark up on that one!
