MZ3 soggy inside

Hi there, Its just after winter and I have finally managed to dry out the inside of my Z3M.
I cannot see anywhere specific where water has been ingressing but the floor on the passenger has been saoked with clean water so a hole in the floor is ruled out. I reproofed the roof last year and I think I need to do something to stop this again. The window on the passenger door doesn't really meet up with the seal from the roof and I think this is the source of the leaks, what would be the best thing for me to do? Its finally dry inside and I want it to stay that way. Any suggestions/solutions would be welcomed, thank you, Peter...Scotland

The top of the window seems like an obvious place for a leak. There is a window height adjustment inside the door. While you have the door panel off, check the inner seal where the plastic sheet or foam (depending on model year) is sealed with butyl tape. A leak in this seal can allow water to run into the car.

Another common leak is the A-pillar seal. There are others.

Toward the top of the forum page, on the right, is a button called "Search This Forum." Click on that and type "Leak" or "Wet Carpet" and you will get plenty of places to look.

Thank you for your reply, I followed your advice and looked a few of the threads on the forums that have had soggy floors, will do some investigating at the weekend.
Cheers
Peter
