Hi everyone, wondering if anyone can help. I've just got my z4 about a week ago, 06 plate roadster with manual folding roof ( no motor just a handle in the centre). But when I hit about 75 - 80 mph an unbareable whistling noise comes from the roof as if wind is screaming in. I'm talking really loud. Has anyone else had this problem or does anyone know what could be coursing it or how to stop it? Thank you very much,
Andy
