Cabin Window Leaks

[Mellowg]

I'm a recent owner of a 2011 Z4 sDrive 30i and experiencing water leaks from the rear top of both windows. The used dealer I purchased the car from says that it is common in Z4's. Is that others experience?

No leaks from mine unless I use a pressure washer and then I get the odd little bead, it would probably be a good idea to use some gummi pfledge on the rubber seals.

Gentlemen- Thanks for the tip. I will give it a try.

The rear quarter light on my car tilted back, so the black strip didn't seal against the front glass. Why it moved don't know.
Didn't seem any adjustment. Packed with washers to tilt it forward. Looks now to need a bit more adjustment.
First i knew problem carpet behind seat wet.
Picture is off ebay but you can see sealing strip arrowed.

Thanks Flybobbie - It looks a bit over my pay grade to disassemble.

I never removed the mechanism, once the plastic was removed i just used some washers and bit of fiddling to tilt the glass'
Could do with a bit more tilt, but dry at the moment.
Just compare both sides of car to see if different.
