Thanks to another thread, I realized that I did not have this tool in my toolset. Drove down to the dealer and they gave me one. Looks like BMW stopped including this tool starting 2008 MY (mine is a '10.) It's a right-angle Z shaped allan (Hex) key. Check your toolset. If god forbid your car is disabled with the sunroof open, you will not be able to close it without this tool.
