2003 BMW 525i Question: Water leak
Remove the door trim on the side leaking, check the foam membrane is properly sealed. They leak due to improper resealing after work is carried out. - Chow
I have the same problem. I'm taking it in to get fixed this week. Hopefully it won't cost too much since this is an obvious defect from BMW. I also noticed drips of water hitting my foot so that should be fun to find out what that is. - grimmtas
What I found was very simple. There are two drains for the ac running under the center counsel. They easily become clogged thus water running out of the underseat vents. Poor design but an easy fix. Under your car you can see the drains straight in from the "c" pillar. Simply put your air gun to the drain and one quick shot will open the clogged drain. 25-30 lbs of pressure will do the job. This is common in 7series and X3, X5 and some 5series cars. This is likely the real problem. Hope this helps, and hope they charge you nothing if you cant do this. It would take a mechanic 10 mins!! - Visitor
It was the vapor seal for me. The dealer fixed it for $200. - Visitor
