It was the roof release for the non-electric roof version - I think it still allows the electric roof to be closed manually if you pull the cord that goes through to the boot first
Ah, the age old question. I've had it off and it appears it does nothing from what I remember :lol: I think it's the manual roof release, possibly in countries which don't have standard electric roofs?
Mines an 07 and it has it, even though it doesn't have the catch at all. I guess it was cheaper just to leave it there... Though it's just another thing that can rattle eventually :roll:
Some other markets had a single skinned manual roof. All cars have the release catch tho as it It's the manual release for the roof should the motor fail- you press this and pull the release cord in the boot. There is a Allen key tool to secure roof in the toolkit. Hopefully you will never need it!
