    Hi,

    I have just helped a friend bring home a 2004 A4 1.9TDI multitronic, it was involved in an accident, he bought it bent, had it repaired and have just realised it is refusing to start.

    The ignitition switches on fine, DIS says press footbrake to start but no gear position shown in the bottom section (can't remember if it should on not at that point)

    Odd thing is that with the key off the gear selector is locked in park, but as soon as the key is turned it is free to move to any position (without the brake pedal pushed) which isn't right.

    I have scanned the car for codes, the engine showed

    18034 - Powertrain Data Bus: Missing Message from TCU

    the ABS showed,

    01826 - Sensor for Steering Angle (G85); Supply Voltage Terminal 30
    18055 - Check Coding of ECUs on Powertrain Data Bus

    18034 again

    I could not connect to the transmission.

    Apparently the damage to the car was around the base of the A pillar on the drivers side behind which there is various electrical components so speculation is that something has been damaged in there.

    Any ideas what to look for?? Help gratefully recieved

    Anyone??

    I should add that it won't crank, just as if the gearbox inhibitor is working all the time.
