Passenger Window

[Kinglewis]

Hi , I have recently purchased 2006 z4 roadster. When I close the roof the passenger window sporadically goes up and down a couple of times and then settles in the middle halfway.
The mechanic says I must bring the car to him when it happens.
This is not possible as I have no idea when this is going to occur.
Please help !!!

If you search "window reset" on here that could possibly cure it for you.

Cheers, tug

Thanks. I have reset. As it only happens sporadically I will only know in time if this does the trick
