Pano Roof Issue

[S99]

Hi,

I have a 2006 E53 30d with the Pano-Moon roof... a great feature although it doesn't function.

The sunblind retracts fine and the front section tilts but that is all - when trying to lower it stops about 1/2 inch above where it should be and can only be lowered by manually pushing the glass down. When closing, the sunblind is also juddery - you have to keep sliding the button multiple times to get it to close.

There is lots of wind noise when driving and the rear section of the glass seems to have a lot of movement when 'closed'.

I have tried holding the button for a full cycle as I've read online to no avail.. any ideas or suggestions would be great.
