I have this problem on my 640i (also frameless windows). The window will start going up, then hit the safety-stop (as if something was in the way) and wind down.
What I have noticed:
- Never happens when car is in motion (even crawling at 10km/h)
- If it does happen, sometimes pressing the switch down again (window will wind down a few extra mm) will result in a full close again - but sometimes not
- Pushing the window down into the door manually will always result in a full close again
I have tried to reinitialise the window (full down, 4 clicks down on the switch) but this has no result, the one-touch close still works after this.
Car recently got a new battery as I thought this may have something to do with it.
Any suggestions?
