BMW e46 Coupe Window Loose and tilting out

Hi, I have an BMW e46 convertible/coupe where the driver side window is kind of loose in tilting and also tilts out a little bit. This causes the window to not slide up in the seal properly when closing the door. I have adjusted the window as much as I can by removing the door-side and turned the adjustment screw to full tilt-in. So that it should tilt inwards as much as possible, but it still tilts out. I have also checked both tightening screws and they are both very tight.

I have noticed that the black "guide" or whatever it is where the mirror is attached to is not tight against the window from the outside. Could this be what's causing the window to tilt out or what can it be otherwise?

Appreciate any help, thanks!

sounds like youíre going at the issue correctly by trying to adjust it. I do know there is a rubber/felt channel where the glass runs down. sometimes this falls out giving it slack.
the other issue is if you adjust from inside the door the screw turns the other way. this mistake is because itís made to be accessed/adjusted from the door skin side. access hole under the rub strips on doors.

as for your side mirror, I do not know.

Yepp I know it turns the other way. I've tightened it really quite hard but no difference. The glass holders that slide on the metal thing are both fine and I can't feel any looseness in them

mirror has nothing to do with window being loose, that bolts on to the door frame itself...sounds like maybe your window track is bent, was there an attempted break-in? Try taking the inside door panel off and see if the reg is loose or if the window part is bent, if you screws are tight already you do not want to over tighten and strip them....just saying I don't know anything but there's my two cents....

Yupp they're tight. I do recall something about maybe a break-in. Not sure though. Although I do suspect that the car has been in a accident judging on some other problems and broken parts. I will try to tilt the whole window track by putting some screw brackets between the door frame and metal tracks tomorrow to see if I can get some more inwards tilt

I have the same problem, OP. My bolts are tight and Iíve tried multiple adjustments. There are some green tabs missing from my assembly inside the door. Not sure how essential they are but it does look to me that they can affect alignment ever so slightly.

Interesting, I've never seem to come across anyone with the same problem. Does your window also go up on the outside of the seal when you close it? I have temporarly placed a silvertape tab on the inside of the Windows so I can drag it inwards when I close the door/window

Mine goes under the frame correctly but it doesnít tuck up as high as it should. Mine also catches on the B pillar when I open the door. Real pain in the arse. Makes an awful noise.

My friends coupe had the same problem, it ended up being the window regulator itself was actually bent from people closing the door by the window glass.

Window wobble fixed!

So my wife's 330 CI convertible had the same issue for years. When you closed the passenger door the window was loose and would not seal correctly against the upper weather stripping and she would always have to roll the window down slightly then back up to get it to seal correctly. Here is how I fixed it. I first removed the inner door panel. There are plenty of videos out there on how to do this. I then checked the clamp holding the glass in place. It was tight and had little play in it. I then checked the bolts holding the window guides in place. They were also tight. I noticed that there was excessive play in the window against the felt stripping close to the door latch compared to the driver's side door. I then removed the felt stripping on the inside of the door. I then rolled the window all the way down and then used a hammer to carefully bend the last 4-5 inches near the door latch that the felt strip was hooked onto. I probably bent it in about 1-2 mm. I then put the felt stripping back on and rolled up the window which fit more snuggly against the felt stripping and outer weather stripping ... no more window wobble and the window now seats properly when the door is close. And most importantly, wife is happy.
