Hi. I recently bought a 2008 Series 1 convertible and there is a slight rattle coming from the front left side of the roof when the roof is closed. It stops if you put a bit of upward pressure on the front of the roof where it meets the windscreen. Is there anything I can adjust to stop it, without it being a major job. I imagine it may be a bit of play between the securing lever and whatever it fits against above the windscreen. Thanks.

If anyone else has this problem I've sorted it. The front plastic trim is held in place with 6 plastic grommets and star head screws. The screws were spinning in the grommets so were not tight enough to hold the trim in place. 6 new grommets and screws cost less than a fiver from BMW ( I know, I expected to pay 4 times that amount). The grommets simply push into place and the screws tighten into them.
