Open the door and operate the latch mechanism manually by using a

latch is dirty and needs to be cleaned, as per my earlier post.

I can't persuade the window to drop/raise by manipulating the latch like that, but just this morning it unexpectedly worked on its own. Great, now it's an intermittent problem :-(

Also, it seems that when the window is put all the way up using the normal switch next to the gear lever, it sometimes stops working - the normal switch no longer raises/lowers the window, although I can hear a clicking from near the motor. To make it work again, I have to open the door and switch on the ignition. Then I can lower the window a fraction, close the door, and then when I set the (3rd-party) alarm-immobiliser the window is automatically closed.

Could it have forgotten where the window is? Does it need training somehow? Could it be that the window position sensors (if any) have gone flaky?

It's too dark in the evenings at this time of year to do anything fiddly like taking out the door latch, so it's going to have to wait till Saturday morning to be cleaned.

I live within thirty minutes walking distance of a specialist BMW dismantlers, so swapping parts at random is a possibility although I realise that's not always the best way of solving these things.

I'm confused. I thought you said that the only trouble was that the window did not drop the half-inch (13mm) or so when you open and close the door, now it appears you are saying the window does not operate properly by the window switch.

The retraining for the window is only needed if the Auto-Up feature does not work. To retrain the window, you have to hold the switch at the 1st detent for the entire travel of the window.
