E90 question

I know this is an e30 forum but I know a lot of you guys have knowledge of other bmws also.

passenger side rear floorboard keeps filling with water. I cleared the sunroof drain. It drains as it should. I cleaned out the under hood vents. I don’t have an air compressor so I couldn’t blow high pressure air in so it may still be that. But the floor board keeps filling with water QUICKLY and idk what it could be. It’s coming from underneath the floorboard carpet it seems cause the side of the carpets are still dry. Ideas?

Has anyone worked on that door? Like to replace a regulator or anything that disturbs the vapor barrier? Are the door seals still glued on? Are you parking on a sharp incline/decline?
