water in passenger cabin

'03 325i premium pkg. sunroof. We're getting water on the driver's side floor in the front and the back. Any ideas where/why it's getting in? The trim piece above the windows on both sides of the car has a small gap, as if the piece has shrunk. I'm guessing this is not the source. Thanks for any help. It goes to the dealer under warranty on Thursday...

Have the moonroof gaskets/seals checked. If water is making it inside through there, it could funnel its way to the a and b pillars, ending up in the carpet.

This has been known to happen in other BMWs.

IF the window regulators have been replaced on that side then often times the vapor barrier (large gray foam looking barrier that seals the inside of the door) will either get torn or possibly just not re-installed correctly. Also sometimes they can just leak on their own. The only way to tell is to remove the door panel and inspect the vapor barrier for leaks. This is one of the most common e46 water leaks.

I'm going to go with DRZ on this one, I've seen this happen most commonly after the sunroof has been worked on.

Thanks for the replies. It was supposed to get checked out at the dealer today, but they didn't have a loaner car as promised. Counter guy had to deal with my wife for that.

The driver's side regulator was changed around Christmastime, but it hasn't leaked until recently. I do have a moonroof. It hasn't needed any work yet. I'll let you know...

The dealer went for the window regulator. Not just the vapor barrier...they replaced the regulator. So far, no water, and it's like monsoon season down here!

Let me amend a previous post. After seeing the work order the only thing done was replacing the vapor barrier properly. Again, no more leaking!
