The 15A fuse for my cigar lighter blew on my A3 1.8T this morning whilst I was attempting to pump up my tyres. Any how I decided to swap the 15A fuse for my radio with the cigar lighter fuse (so I could at least pump my tyres up). On replacing the Radio with a new 15A fuse my concert Radio says SAFE and won't do anything. Presumably I've now activated the theft deterant and need to input the security code- One slight problem is the car never came with a radio code (the manual has the bit where it was filled in but for security purposes it was torn out). Is there anything I can do besides contacting Audi to get the code? Thanks, Jon.
