HELP Water Intrusion Into Passenger Footwell

Lightningfastbmw · 04-26-2019, 09:46 AM

Hey all! I have a 2011 BMW 535i (F10).

Recently went through the car wash and after coming out and vacuuming the interior I found that the front passenger foot well is soaking wet.

I know that the water was not there till I went through the wash as I had left a few papers (dry) in the footwell and that they were wet after.

Had looked through the forums and other owners had the same problem but i could not find a solution to my issue or any videos on how to diagnose/fix the problem.

Any information or help would be appreciated!! Thank you

Main suspects in my experience - vapour barriers in the doors (talked about a lot recently) or sunroof drains.

Vapour barriers is mentioned in here: https://f10.5post.com/forums/showthread.php?t=1557085
