They did originally look into the mirror and were liaising with the factory. The factory determined it was from an external agent so didn't see much point in arguing any further and paid for the replacement. The identical thing has now happened again to the other mirror. It has never been twisted backwards.

I believe you may be correct in the issue lying with the control module. Just slightly concerned why they didn't identify that last time they had the car. Was without the car for 4 weeks last time, now left with a non functioning car once again and awaiting for the factory to investigate this. Have the dealer also saying because they are moving Parts factory currently in Italy, the lead time on the new mirror will be in excess of two weeks which is all a bit frustrating.

Thank you for your responses.
