rear door rattle caused by ...
 

the panel at the very top of the door where it meets the glass has come loose (circled in red pic 1). It can be pulled a bit out toward the interior of the vehicle (pic 2).

The other rear door panel doesn't pull away from the glass at all so I'm wondering how I can latch/pop it back in. I've tried both and it's not obvious. If someone can tell me how to pull it out so I can look at it, that would work too. RealOEM shows all the parts but I'm not sure how it latches. http://www.realoem.com/bmw/showparts...33&hg=51&fg=50
