    Can you get access to VAG com, as this should find the fault.

    You will need a volt meter and figure out what comes live when switched on
    you can look inside the lights to the back of the plugs and work out what goes where
    Vag com aint going to help thou
    why does everyone think these days that if theres a problem it must be sorted with a diagnostic machine .

    All the wires obviously correspond to actualy wires going to bulbs etc
    so you can visually sort the wiring out by the process of tracing wire from bulbs to pins internally in the lamp
    its a bit of a drag but can be done without a tester .
