Passenger door sill plate leak
All,
Hoping someone can help here. I got to my car after work and noticed that the carpet was wet on the front passenger side floor closest to the door. In looking closer I noticed water was dribbling in on the door sill plate seam closest to the front of the car. I have no clue where the water is coming from. I checked the door seals and they seem fine. Does anyone have an idea? Please help. Thanks.

sounds like it could be your windshield....or possibly the cabin air filter housing cover is not seated and sealed properly...
have you had a new windshield put in recently?.... JP |

Not sure if this is a classic E90 problem or not. I'm guessing not since no one posts about it often. That would be the first thing I'd check. The sill logo plate is a wet zone. There is no critical seal there to keep water out of the car. |

Well i ran my car through the wash yesterday and and as soon as the wash was done I jumped out and opened the passenger door. I could definitely see water dribbling out from between the door panel and door skin. I picked up some new door panel clips and plan on pulling the panel off and looking at the foam sound/water barrier and resealing.

On my E39, there wasn't much to break about the clips. I'll be interested to see some pics of how different the E90 might be. Sill logos are a different story, those clips seem to break when you look at them funny, but you shouldn't need to remove that. |

Check the door drains first!....they are located along the bottom edge of the door...there should be 3 or 4 of them. they are probably clogged with leaf debris, dirt or other stuff...a plastic trimmer cord material or similar will not damage the paint and you can run it up in there to clean it out....
The vapor barrier alone was not designed to hold water at bay in liquid form...just moisture.....if the water has gotten up that far because it cant drain...you have a potentially bigger problem...like eventual rust and electrical gremlins.... JP |

Just got done popping the door panel off. I did not see drain holes on the bottom of the door, but did see two grommets that were about the size of $.50 pieces that I popped out and examined. What was odd is that there were no holes in them indicating they were for drainage. I did not find any debris in them either.
I did find that the bottom of the vapor/sound barrier was in fact detached from the black urethane caulk/sealant. I pressed the foam back on, but will probably be pulling the panel off again and heating the sealant with a blow dryer and reattaching. Didn't have time tonight.

The drains cannot keep up with high water volumes (car washes, torrential rain) and the vapour barrier is meant to hold it back. |

I ended up finding a small tear in the sound insulation/vapor barrier (See pic) that was allowing water to get in. I tried patching with some Gorilla tape, but no go. I have ordered a new insulation piece.

As for the drains, the only hole I could find in the door seam was one toward the back of the door close to the 'B' pillar. Should their be more drains along the seam?

UPDATE: My new door liner came in as well as the 3M Window-Weld (same stuff dealer uses). Put the new liner in and will be taking it to the car wash this weekend to test for leaks.
