    A4 2.5TDI B6 AKE, no boost when warm, 00519 fault code.....

    its probably linked to your ecu on your model. if its not on the black plastic inlet manifold pipe, then its on the ecu.

    If only my problem was as simple as that! As nonenails says, get your boot sensor switch checked out. I bet that is the only problem. Your alarm siren batteries are probably dead too but that wont effect the arming of the system

    Advice needed please - Audi A4 B5 Avant facelift model electrical issues

    Im guessing the pump is an incorrect pump, as you pointed out, or a faulty one. It cannot be recoded at all, won't accept 13130 or anything at all. Also the current coding is the maximum number/value tha vcds will allow to be entered (0-32767) and i suspect this is a sign of a fault. Wen i...

    Advice needed please - Audi A4 B5 Avant facelift model electrical issues

I reeatedly tried recoding it to 16140 but no joys! Is it because im using kwp2000? If i use kwp1281, the fault code...
