Hi everyone, I really hope that someone out there can help me. I tried to open my roof last week after it not being used for a few months and after a few moments of horrible clunking noises it decided to begin to open/lift on the right hand side and not the left. The blind works fine and it closes perfectly but when I try to open again it does exactly the same and slightly opens to the right then stops as the roof twists out of shape. I know where the motors are, and hand cranking obtains the same results. I believe it could be a broken rod which operates the left side but does anyone know how I can find out and repair as any of the components seem almost impossible to reach without opening the roof. I am a generator maintenance technician by trade so am not afraid of the work but would really appreciate some advice from someone with knowledge of the workings of these roofs. Many thanks in advance. Regards, Gavin.

I don't know anything about the panoramic sunroof, but it sounds as if it uses a similar type of drive cable to the older sunroofs. When the cables kink you need to apply hand pressure to help it along in order to open it.

There's a DIY thread on the W210 style sunroof. Have a look and see if it gives you any hints.

Unfortunately the cables tend not to be covered under warranty, but worth asking.
