Mines doing it. But noticed that the cogs are as follows. 1 plastic cog on a metal rod with a metal cog at the other end.
The metal cog turns the mechanism, and the plastic one is driven by the motor. Noticed after titting about do find a leak the other week that mine started working fine again after pushing this rod. You can see the end of it if you remove the roof console. Literally all I did was push that end in 1-2mm and it started working again!
Seems to have slipped back again though.
The motor is seriously expensive from renault, but Paul at Infinicar quoted me only £60 for the full sunroff (mechanism, motor, glass and frame)
Try asking Paul. But just out of interest try pushing the end of that rod I mentioned.
Its in the centre of a circular shaped bit of metal on the motor, pointing vertically upwards.
