My Car is 2008 - (new shape) C5 Exclusive. The LHS mirror folds when the engine is turned off – BUT – it over-rotates past the 90 degrees and clunks into the door. It’s a fairly “glancing blow†so sometimes the mirror’s rotation is halted but sometimes it carries on a way. Then – when the engine is restarted, the mirror folds out successfully to the correct position, unless it is caught on the door sufficiently that the power of the motor can’t overcome it. So – whatever senses that the mirror has rotated enough when the engine is turned off clearly is not working – but opening is fine. No joy from various Citroen dealers, “you’ll need a new unit at £300†was their reply. Nor so far from Citroen UK Any ideas? Many thanks
