Lost radio code sheet for Audi V8 1990 and trying to avoid dealer fees for retrieval. The biggest issue is that the radio in the car she had was not the one registered to the car originally so over the phone they were having trouble retrieving the code.
Sorry....your code will only be available from someone with access to the Main Dealer database or the unit will have to be taken into a Radio Decoding Service
It is unlikely to be available for free from anywhere on the Internet
