I assume you didn't buy your car from an Audi dealer. The proceedure for
getting the code goes as follows:
1. remove your radio and write down any numbers that are printed or
stamped anywhere on it.
2. write Down your VIN number.
3. call your local Audi dealer and explain your situation. They will take
those numbers you have written down and enter them into some computer.
This computer will give them the code for your radio. My dealer gave me
the code over the phone, which I suppose sort of defeats the purpose of
the whole *&(!@##$ anti theft radio pain in the *SS. But maybee I just
have an honest voice. (Soon theives might get smart to this and write down
your vin no. before they smash your windows)
4. GETTING THE CODE IS ONLY HALF THE BATTLE. if you dont have the
specific book for your radio, find out the EXACT proceedure for ENTERING
the code. I had the very frustrating experience with my 90 coraddo of
having the code but having no idea how to enter it. VAG changes this
procedure very often so what works for some radios will not work for
others. Your proceedure will probably be different, but just to
illustrate the complexity of the operation I will describe how it is done
on 90 vw with the Heidelberg head unit.
1. turn on the head unit and leave it on for at least 30 min. to
clear the memory of all improper keystrokes. If you make a mistake the
first time you must turn it off, then back on , and wait at least an hour
to try again. Make a second mistake and you wait 3 hours, make a third
mistake and the unit must be sent in and reprogrammed!
2. then press and hold one button (ive forgotten which) then press
and hold a second button.
3. the word "code" should appear in the display. now you enter
your code. Say your code is 4321. You do not press the (memory) #4 button
then the #3 button and so on. Instead you press (memory) #1 four times,
then the #2 button three times, the #3 button 2 times. etc...
4. then you press and hold a different button then press another
button and release the two simultaneously.
As you can see it is a major pain in the ars. I had five vw technitions
trying to remember all of the proceedure after being told the wrong one
over the phone for several days. They finally got it. All this just for
changing a battery! now i just CAREFULLy hook up my trickle charger to
the battery cables befor removing them so the car has enough juice to
maintain the memory in the radio while I change batteries. That way the
radio never knows it was disconnected.
By the way , If you bought your car from an audi dealer they should have
told you all of this. They may not have known your code but they should
have at least told you how to get it.
hope this helped.
