Panaromic sunroof ratling noise

[pbx]

There has been ratling noise from sunroof , it started making noise just after 22000 miles.
I bought it as brand new so still under warranty , been to mercedes benz twice , all they have done is did some checks and greesed it, hasn’t really helped since. Waste of time.
Has anyone else had the same issue, what can been done to avoid the ratling noise it can be cery annoying sometimes.

You can try silicone sprays on the rubbers , Gummipledge is meant to be very good . What your hearing is rubber on rubber . One of the reasons I sold my e350 was the roof creaking , especially in colder months. I stick to tin tops from now on.
