How about just using something like this?
I had this problem with mine when I first purchased it but on the passenger side,
It turned out to be one of the motor control mechanism had broke,
Replaced it for £10 from a member on here and all is good again,
Whilst we are on the subject is there any way to recalibrate the flaps?
On my mk5...
I have not owned the Audi for long but I noticed last night when I turned the car off the wipers just stopped, I expected them to auto park back to the bottom of the screen.
Is this correct to how the should work or should there be some kind of run on after the ignition is turned off?
