    Apparantley the b8 does not have a fuse for the reverse lights,the switch i think sends the signal to the control module and it sends it to the reverse lights,unless some coding or something is not right,if it was the wires,then i t would not light up the bulbs when doing a output test,doin my head in :keule:

    Is your car a manual ?. Looking at the wiring diagram for mine which is a B8 manual the switch on the gearbox connects to the onboard supply control unit directly.
    This will then communicate the gear information to the modules that need it over the CAN network. That would include the convenience module which is the one that seems to control the lights at the back.
    sounds to me like it may be some kind of error in coding. Has anything been changed on the car recently.
    I would look at the onboard supply control unit and see if any faults are flagged.
    There may be a measuring block that will show the gear the car is on, If this shows reverse as being detected then it's down to a coding error I would say.
