W202 sunroof disassembly
 

Any tips on how to get inside the sunroof on a 2000 C230K? Mine still works, but it makes popping noises as the roof goes back and forth. Also, the sliding shade encounters a lot of resistance at varying points along the track when I try to open it and close it. I suspect the two are related, but I'm not sure how to visualize the parts better. I've done repairs to a W124, but the parts seem better hidden on the W202.

Thanks,
Anthony
