My dealer had to replace the stereo in my 2001, and I reminded them every chance I got to give me the radio code. I think they had to pull the unit from the console to look at the serial # & then email VW C/S for it. You probably could contact VW C/S at the toll-free # & give them the serial # of the unit. Just explain to them the dealer never gave you the code card. Unless the power to it has already been disconnected & it is locked up, don't unplug the power harness - just slide the unit out & look for the #. The dealer should let you borrow the radio removal tools for a few minutes in their parking lot. Now, if I can just get the key code to my car - the little black tag was not there when I bought the car.
