Tailgate glass opens while driving

Off and on we've had problems with the tailgate glass having a mind of it's own and open by itself even while driving. We've had it looked at by various dealerships and they all claim to have fixed the problem. However, since this is an intermittened problem it's difficult to say if they truly fixed it or not. Well this week the glass started acting up again. Does the tailgate wiring harness control the glass portion of the tailgate? AFAIK the tailgate wiring harness hasn't been replaced on our car. Or is it a defective microswitch?
Thanks,

Sytner said it was a very common problem and changed rear window pushbutton for ?107.85. For a while it was OK.
Then it started again. Next time Sytner changed the rear screen wiper motor / central locking motor for ?263.80. Now OK.
Luckily I had second hand AA 3 year warranty so it was paid.
Make sure rear wiper is free to rotate. At one stage mine had seized due to lack of lubrication. It needs checking regulary.

Well my wife took it to the dealer yet again. They haven't fixed it yet as they had to order a part from Germany. Ill keep you guys posted.
My 2 year old 520 D M has just started to exhibit the same problem. Could it be the cold or damp problems after the thaw, it had been standing for 10 days over the Christmas break with upto 8" of snow. will be heading for the dealer next week but it is a problem I would like to get a better handle on as I always prefer to be in the driving seat when raising issues. Have had a quick look to see if any leaks but nothing obvious. Another thought could it be 'fixed' by a reset with temporary battery disconnect?

My car developed this problem today so I'd love to hear if you found a solution to it. I'd imagine it would involve a reset, rather than parts replacement, although most BMW dealers probably wouldn't tell you that!

I am betting the cold weather is not helping..

Yes I too have the same problem until i fix it my only option has been to get into the car and before starting press the "central locking button". in addition i have an Alarm saying "increased battery discharge" and please set "time and date". Another interesting option has been noticed that if i set via the I Crash button to quickly I get a very interesting message "All Driver Aids Disabled, please drive responsibly" on the dash the ABS and DTS light up.
