Rear Seats Wet After It Rains?? - BMW Forum

sy5alive · 01-08-2005, 03:00 AM

I have a 94 318is and lately it's been raining like mad here in California. My backseat passengers are complaining of having their asses soaked with water coming from their seats.

Upon further investigation (probing my finger into the seats), I've found that there is moisture in the foam underneath the seats that although does not thankfully stink, is a nuisance to my passengers. This only seemed to happen after it rained. Any suggestions on what is going on and how to fix the problem??

that is the wierdest thing ever? The only thing I can think of is condesation....somehow water may be condensing and pooling under those seats....how water is getting in depends on whether yo drive with the car open...or not...

I guess that didn't help...

but do you have a convertable and are your seats leather or cloth?

Look around the seal of your back window. I have a friend with a 5 series around the same year and his seal is bad. It is not that hard to remove the window and replace the seal and moulding; both have to be replaced at the same time. Try taking a water hose to your car a just spray all around the window to check that. Good luck.

Do you have a sunroof?
The sunroof drainage ducts can get clogged and the thing just overflows and leaks into the cabin.

Take the rear seat bottoms off and inspect all around it. If it's not leaking from above, it's coming from underneith (or the sides from osmosis). The airbag G-Force sensor is under the middle rear seat, so try not to damage it. (not for fear of setting them off, but for fear of damaging the unit's functionality) I'd fix this SOON since you definately don't want water around the airbag g-force sensor... Random airbag detonation or no airbag detonation is a bad thing... Not to scare you or anything and it's HIGHLY unlikely it will randomly detonate but it is possible.

I still think it's the drainage ducts leaking in one of the rear pillars which is just draining into the passenger seat.

I'd say it is the sunroof also. I have had this problem with a Passaat and now my 325is. Mine is filling the spare tire well with water though. I blew some air through the sunroof drains but have not checked it since. They can be a pain to get cleaned out though. Good luck.

Thanks for all the help and thoughtful answers. My tire well is not filling up and my seats are sports leather. I'm thinking it might also be the seal for the back window but I'm gonna check the sunroof as well.

If your spare tire is getting flooded is because the rear drain pipes for the sunroonf go out on the rear of the car.. maybe accidentaly druing some repair the pipe was pulled out of its hole and then the water goes into the car..

romove the side carpets and look in there, betweem the exterior metal panel and the car body there will be a black round tube. it is almost hidden look in there, youll see it. the pipe has to go truoght a hole on the bottom part of the cars body/./ look on both sides to make sure they are going trought the hole, and that there is silicone of something to seal the sides of it.
