for me the dealer actually openned the sunroof and installed some plastic pieces somewhere and changed the torx and lubricated.
was good for like 5 days. no creeks on normal bumps, only on high inclines.
but after the 5 days i can now hear it a bit on normal inclines. the dealer said they've been talking with the support and got instructions from them as they have a number of owners with the same problem. but he said this is not a final solution. and i will have to lubricate the sunroof at least with every service.
i am sort of cool with it at the moment.
they also fixed the rattle in the door. thanks to the tips on these forums
