My BMW 528I has the same trouble. One of the front drains is blocked. I think from someone driving on a curb. The bottom of it is bent in the way. I ran a metal wire down it and it doesn't help. I don't know what to tell you to do.. But there are 4 drains. They come out just behind the front tires and just before the back. If you look into the edge than runs in the sunroof you will see them. Fill them with water and you will see which one is clogged and where they come out. I havn't fixed it. I just left it and make sure or at least try to park on an incline or flat ground. If i do park on a decline i soak up the water before i drive out. hope that helps
