E92 Window Air Leaks

hybrid90 · 01-06-2020, 10:45 PM

I've been looking all over the forum and the internet, but I can't seem to find any information on this. Last year, I went from an E90 335i to an E92 335is. First thing I noticed was that I would occasionally get air leaks around the driver and passenger windows. It is much more prevalent at higher speeds, when it's windy and those are both even more noticeable if the top is closed (I"m guessing the air pressure since the car seals up so well).

Does anyone else have/had this problem? If so, how did you fix it? I've examined the seals thoroughly and they are in good condition. So the only two things I can come up with are either the windows are not going up exactly as they should (the rubber guides in the front possibly being sticky/dirty/not smooth) or that the door is sagging just enough to create a slight misalignment. From the outside the doors look like they are lined up but I know that there might be more to it.

Any help on this would be greatly appreciated.

As mentioned in the thread that Phil325i posted, check that your door is flush. Moving that door striker in by a millimeter could fix that wind noise.

I need to do this on mine as well, I know the preload is off as I saw the thread before , and checked mine. Have not adjusted yet however.
