I need to replace one of the upper (main beam) headlights on my 04 Multipla, the Torx screw turns but does not unscrew so presumably a kept nut is turning. Any ideas please.

Also I have an 03 Multipla which has collapsed rear suspension, it has a really excellent engine and gearbox despite its 150000 miles which can be heard running. Is anybody interested in giving me the scrappies price of £100. The engine really is too good to go in the crusher. I am in NW London

I think the screw under the cover just screws into the plastic of the upper head lamp, try pliers on screw and pull up while turning anti clockwise.
