Depending on the nature of the problem, we might be able to check it out at Village VW. We work on a number of Audi cars from time to time. Have your friend contact me directly at the shop (info. is in my profile) and I should be able to tell them whether or not we can help...I'm one of two technicians who they usually end up with. Besides us, you can also try AG Imports, off of Hwy 58. Ask for Rick there too. (They're the ones that used to be out off of Ringgold Rd).
