My 2001 S4 Avant had a tire let go on the way to the airport at 5 am last Thursday. I called my local Audi dealer, and they dispatched a towing company and recovered my car and took it to my house. I just got back from Mid Ohio, and now the car wont fire. They must have by passed the alarm somehow and I guess it's in permanent anti theft mode. The ECU light is on in the tach dial. What can I do on a Sunday afternoon to fix this. There is nothing in the operators manual................
