So i have this problem:
front driver's side window works fine, goes up and down with no issue. However, when it's almost bottomed, it sounds like it falls...like it smashes down the end of the regulator.
Could it be some kind of window-stop inside the door?
How could i possibly fix that?

The window glass is attached to the regulator by two brackets, one each side of the glass. There's a single 8mm bolt on each bracket that secures the regulator runner to the glass bracket.
- Its possible that one of those bracket bolts has fallen out.
The regulator runners run on cables. Its possible that one or both of the runners have disengaged from the crimped sleeve on the cable that drives them. That's what happened to mine.
Open it up and take a quick look. If its just a bolt you'll probably find it rolling around the bottom of the door. A magnet is your friend. If its a regulator, buy the Uro for $60 or so. Good DIY here for the R&R.

Thank you Elbee, re fixing front window regulator

Just like to say I was going to order a window regulator, and was going to fix it myself. The I came across your post (think it was yours!) saying you used a 'pull tie'... well this gave me an idea, I didn't have of those ties, and found some metal picture hanging wire, and wrapped that around it and tightened it around the regulator clip and the cable with the metal lodging part, and bob's ya uncle, it worked! And still does, I thought I was going to save myself about 120, but instead saved myself about 150-160 ! Job's a good'n!!

Great Thread

New here, hopefully not digging up an old thread. Bought my GF's '03 325xi last fall, have been with the car (and the GF) since she got it in '06, I've driven it on ice and, needless to say, I love this car!

Back on topic, I just completed this repair today, really REALLY cool that this forum directed me exactly to what was needed. My only cost.. a couple of very minor metal edge cuts on my hands.. no band aid necessary! And four zip ties.

Only thing I'd add to all this is, keep in mind during reassembly, the alignment of the "nut clips" is pretty important. I had one of the clips for the airbag break in half, only learning this when I found it in the bottom of the door. Two others were very hard to keep aligned. I used masking tape with complete success.

Kudos to BMW for leaving enough room in the door to stick an arm up and compensate for broken, misaligned clip nuts!

Thanks to this forum, just saved me a handful of bux and blood!

Awesome Write-Up

I just did my passenger rear window regulator, just wanted to post one hiccup I incurred. When you are installing the window regulator (be it new or old), be sure to only hand tighten the nuts that attach it to the door. I made the mistake of using a ratchet (I know, I'm an oaf) and I busted one of the grommets, leaving my regulator unattached at the bottom anchor point.

TL;DR, hand tighten the window regulator nuts to avoid breaking them.
