Best bet is to go to an Audi/VW dealership, and have them reset the radio by using a VAGCOM. The other option would be to purchase a VAGCOM yourself (http://www.ross-tech.com/). Of course if you have the actual reset code, you can enter it in manually. I can't tell you specifically how to enter it on the Audi radio, since I have an Audi Navigation system, and the controls are different. But it should be a combination of using Volume and Seek (or other keys the would allow for scrolling) to enter in the code.
No such thing.
yes on the back of the radio.
Insert metal shimms into the radio to relese the radio.
