W205 panoramic roof rattle

[Robconnors1977]

I have a 2016 c220d with a panoramic roof, however it has an annoying rattle over most roads, strange thing is it only happens when its closed. When the roof is open or tilted all is ok. Mercedes had a look and fitted some bits of felt, but still the same!. Does anyone have any ideas as it's so annoying!

On my C63 they lubed the seals around it and the noise disappeared completely. It’s even listed as a service point since it’s so common.
