I have not had to do this yet, but when reading my owners manual it says that if the battery has been disconnected or after a malfunction you have to synchronize the panoramic roof. I've pasted the details below from my 2009 owners manual. Seems pretty hard to me but doable. Maybe it is not the switch.
The tilt/sliding panel and roller sunblinds must be synchronized after the battery has been disconnected or discharged or after a malfunction or if the tilt/sliding panel does not open smoothly.
! Do not attempt to open or close the tilt/
sliding panel before the tilt/sliding panel is
properly synchronized. The tilt/sliding
panel could otherwise lock-up in the open
position.
If the tilt/sliding panel cannot be closed or
synchronized, contact an authorized Mercedes-Benz Center or call Roadside
Assistance.
X Vehicles with SmartKey: Remove the
SmartKey from the starter switch.
X Vehicles with KEYLESS-GO: Switch off the
ignition and open the driver’s door (this
puts the starter switch in position 0, same
as with the SmartKey removed from the
starter switch). The driver’s door then can
be closed again.
X Remove the respective fuse from the fuse
box (Y page 385).
X Reinsert the fuse in the fuse box.
X Switch on the ignition.
X Push and hold the roof panel switch in
direction of arrow 3 (Y page 204) until the
roller sunblinds are fully extended.

X Keep holding the roof panel switch in

the roof is synchronized. Otherwise repeat
the above steps.
