Hello people was woundering if anyone has had this problem? Its not a the stereo system as it a factory fitted one and not a after market one!!! But i have disconected it to elimanate it and no joy!! I have tryed many other diagnostic tools and they dont connect also so its a fault with my car not the tool i have. So when i vag-com it it does not connect and when i do a port test and it shows k-line 1 short to ground!! All your help would be greatfull Thanks.
