Help - 528i leaking water in passenger side
I'm new here, but thought maybe someone has had this experience.
Everytime it rains, my car gets a musty smell. I finally noticed that the carpet on the front passenger side floor board is very, very wet.
I pulled the carpet up and the foam is soaked. I noticed there is some type of black computer box there mounted to the floor or side (under the sound insulation by the passenger door). I am now afraid that if this gets wet, that the car won't start.
So I jacked up the car to see if there was any damage underneath that would let the water in. I saw no damage, but when I jacked the car up from the side, a bunch of water seemed to pour out from the black flat plastic covering that is underneath the car which covers the floorboards. It seemed to be holding some water.
Would anyone have any idea on how the water is getting in the car and how I would fix this? I don't see any damage and can't figure out how the water is getting in. At first I thought through the door seal, but not real wet there. Could it be coming up from underneath?
Please let me know if you have any ideas or experiences.
