I have also just got a C8 2.0 HDI SX and also have the same problem with the door mirrors not retracting ... anyone got any ideas ? Do your rear doors close if you lock the car using the remote ? Ours don't but I thought that they should ... Great car though ... comfortable and nice to drive... I'll let you know of any faults as/if they occur. Door mirror retraction can be manual or automatic - see the users manual on how to set it up. Doors don't close when locking - you have to shut them first, then lock.
