MG3 Hybrid Sunroof Buffeting

[Jobhn2bol]

So I have a very annoying sunroof buffeting problem on my MG3 Hybrid. Even at low speed, if it's completely open it starts drumming and sounds like it's going to rip off. Never had any sunroof problems like this on other cats I owned. As there is no front sunroof dam or pop up cloth screen, I am thinking it's a design issue. What have other found? It's fine if it is used in the back lifted ventilation position. Is there some way to stop the buffeting?

I have a mg zs ev with a sun roof in UK anything over 18./. C i open it, none motorway It has a dam on the front no buffing
