The service advisor was outstanding. But…when I looked at the diagnostic sheet that was left on the seat of my car was for a different car. So, aI do not know what codes were found on my car. I knew something was wrong when I noticed it was the wrong year, mileage and VIN number.

I took my Audi here and absolutely had a great experience! They fixed the issues with my car and it was a very pleasant experience! Knowledgeable honest people and a nice clean shop. Highly recommended!
