when you say code, do you mean the code that the car reads to connect with the head unit? if so then you need someone with a vag com to tell you. try to find a euro shop (not a dealer) that might be able to help you as a freebee or for cheap (the dealer can do it too but there is no such thing as a freebee or cheap at an audi dealer that I have ever heard of)
