Wow.. im suprised that I havent seen this thread before.. I have recently had the same issue in the same place... also in both rear quarters.
Bmw dealership is resolving the issue.. they have ordered new seals/rubbers for me thankfully under warranty.

I get a significant amount of water on the seats when I run through the car wash and when the car wash is on "high pressure".
Wondering if anyone else has this issue?
