Hi guys i have an A3 2.0 tdi 2005, i only have one key, can anyone tell me if i can buy another key (say from ebay) and programme it myself or can it be done by using vag-com. Im sure audi charge around £180 for the key and to programme it, which is pretty steep. And would programming it this way, will it affect the immobiliser. Cheers. Paul
