Hi everyone,
I was passed along this tip, in which I will pass along to you:
If you ever have to work on a Audi/VW radio, and need the radio code, this is how you can extract it without going/paying the dealer.
On the radio you want to depress and hold the RDS and FM buttons and the code will display on the radio.
DO NOT do this more than 3 times or the radio will lock itself out, and you will have to visit the dealership.
This applies on 1998-2004 Systems.
Hope this helps!
-Mr. G
