Hello ! I just bought an 2003 A6 2.7T quattro and I need a radio code because some body put it on. I don't have manual !!!
I wish I got the answer, Iask the lokal audi dealer, bat they don't help me out !

 

Are you SURE you do not have the manual? Did you look at the slot under the steering column for the manuals? If you are missing the radio manual, the ONLY way to get the radio code is to have the dealer hook up the car to the factory system. The car has to be present (used to be VIN and serial # of radio, but they changed systems a few years ago). They might charge you 1/2 hour labor to get it.

 

Thank You for help,... I find The manual is was there just like you sad, but the cod is do not decode my radio what's wrong ??? I do step by step whit the manual !!!

Thank You so mutch your help !!!
