I have a 320 cd '04 plate. My wing mirror has been pushed in towards the glass (cover damaged too) so the 'triangle' no longer sits flush with the door. Although everything still works (electrics, vertical manual fold), I'm not sure whether if it can be re-seated. If so, this will save ££ in having to replace it! The pic attached doesnt quite show it but there is a piece of metal extruding from the frame part. Can this be fixed cheaply?
