Your lucky that’s all that quit working. So joe you need to go to an Audi and have the computers reset for the new battery. There is a tool that should have been hooked up to the OBD port before main power was disconnected

Thank you. I was disappointed the guy who put in the battery did not do this. I found an independent repair shop that only works on German autos. Wish I had found him years ago. Regardless, selling the car. Its time.

So now I did find out from a reputable shop that the Body Control Module is bad. I submitted a question about this. Repair and Sell? $2,000 for repair. Or just take to Car Max to sell?
