Water in rear passenger floor board E91

baggedx · 06-17-2025, 07:55 AM

08’ E91.. had some serious rain the last week, haven’t drove the car in 2-3 days. Got in this morning and rear passenger floor board is soaked with water. My first assumption is sunroof drains, but anyone else have this problem? Any insights appreciated!

Sunroof drain problems tend to be along A pillar/front footwell or in the battery compartment/amp wells in the back. Rear passenger area is very likely bad window/door seals. Open the door and feel along the bottom of it along the gasket. If that is wet at at all, the door is your problem.
