Loud crack noise on c220 coupe

[Petemayz]

Anybody experienced a loud crack type noise on c class coupe with panoramic roof? Only happens occasionally usually when maneuvering on uneven ground. Sounds like the glass in roof is breaking but isn't. Makes me jump every time. Thanks in advance.

I remember our CLC pan roof used to do that. I think it did it when it was frosty/cold.

Never broke

Thats what happens when you have glass panes, in a plastic carrier bolted to a steel/aluminium body. They all expand/contract/flex at different rates/
