    Hi
    Wonder if any of you have any ideas....
    I have changed the motor because the arm had lost its attachment to the motor.
    I can activate the washer and motor with VCDS. Not with the lever/switch.
    No fault codes.
    The coding is correct.
    Took out the switch but couldnt see anything wrong in the board on it.
    Opened the Onboard power supply control unit when I had it in my hand - nothing obviously wrong there either.
    I have at the same time changed the ignition switch due to it having fault codes on it. Those are gone.
    Only fault code left is for the inclination sensor.

    Not stupid question =)
    But tailgate closed - I know VAG is fun of disengaging wiper motors when lids open.
    So unfortunatelly not that easy.
    This is really making me mad.
    I thought that it could help if the BCM was resett - but noooo. It should have been reset when battery was disengaged for about half an hour duriing the change of ignition switch.

    It is puzzling that it will work in output tests but not from the switch, have you viewed the switch inputs in the steering column controller?

    I can't remember if the BCM shows it is receiving that signal, have you have a look?

    Would that be in 09 - Central Electric - group?
    If I remember correct I couldnt see any measuring blocks for wipers, in 09. Only doors and lighs and such.

    Alright - she has been by.
    In 09 - measuring blocks - I can ONLY see front wipers activated. No rear. Searched "Wiper" in Advanced Measuring Blocks. Only the windscreen wipers appeared.
    Further - I checked through all blocks in the Long Coding. Finally got to rear wipers - and all that could be ticked - are ticked.
