X3 Right Rear passenger Floor Soaking Wet...Where is the leak coming from?? Help!!

[matts5150]

I have a BMW X3 and I have noticed that the right rear passenger floor is soaking wet. I am not sure where the water is coming from but this has been like this for weeks now. Does anyone else have the same problem and know where the water might be coming from?? Anyone's thoughts would be greatly appreciated.

Thanks!

Hi matts5150, :xoutpost:

Most likely the sunroof. What year model do you have? This was a common problem on 2004 and early 2005 models.

Also, try running a search for water leaks, sunroof leak, etc.

Hello Ishniknork, thanks for the tip. I have a 2004. I would like to see if others post anything on this. Could it be possible that it could come from the floor (under the car) or is it more likely the Sunroof? Any tips on how to find out where the leak is coming from with out pulling up the carpet and waiting for rain?

Thanks again!

As an owner of a 2004 with a chronic leaking sunroof, my best advice would be for you to take the car into the dealer for repair. I am currently on four attempted repairs. Not looking forward to this winter's rains.

Thanks sfhondapilot..I will keep the sunroof in mind. My car is no longer under warranty so I am just hoping that someone will post some info. on a way to trace the leak.

I had a leak on the drivers side rear and the water turned out to be leaking from inside the door.

You can test this out by pooring water right at the window sill next to the door. Some water will naturally drip inside the door, but in mine it was then running inside the car. I just sealed up the holes for the clips with the same stuff used on the vapor barrier and it worked perfect!

I had a same problem. Dealer replaced rear window regulator and managed to break noise & moisture cancelling shield inside of rear door during installation procedure. After dealer visit, water came in directly from inside of rear doorL

Luckily I noticed this one immediately, removed door panel and made emergency “fix” for noise & moisture cancelling shield. Dealer ordered a new shield and it was fixed on yesterday during inspection II service.

BTW: Based on dealer’s comments, this is very common and known problem (X3 and also with 500 series) like sunroof leaks...unfortunately.

Yes, it's officially called as vapor panel or vapor shield
