Quick update on the replacement mirror
After a few days of Walt Disney's magic formula both mirrors resorted back to their old ways, in fact even worse, as I had to get a second person to assist me me get them both open at the same time.
So D day arrived and like magic both mirrors were working perfectly. The dealership replaced the drivers mirror as agreed, but found no fault on the other side.
They did look at the AFS system, as the light was constantly flashing, but couldn't find a fault. So it was rebooked in for a full check of all the ECU reading to see where the error was coming from. However a faulty connection was found and the car is now completely fault free.
Now the sun is out and the roof is down, so happy summer driving to you all.
