Once again I've found my carpet wet under the the mat on the passenger side? It has been raining off and on here in the Northwest. I just got my car out of the shop and the techs said my drains seem to be flowing fine?:dunno: Again there's a wet spot in the right corner of the passenger side. (under the mat) Has anyone had this problem before? I don't know what to check for? Weather stripping around the door? Or maybe I have a air vent open and don't know it? Another question is how do you shut the air vents on the 530i and could this cause water to come in if open? I'm trying to understand the manual but it's not explaining it well.
