The car has misbehaved a few times of late. The door mirror positions (and seat & wheel etc) are set in the memory per normal. When I select reverse, the passenger door mirror dips so I can see the rear wheel. A few times of late though, it seems to lose the place (literally) and either the dip view is showing the ground about two feet from the car or when it returns to what should be the normal position, again it's showing somewhere several feet to the side. I've started from first principles - set the normal driving position, press M and 1 at the same time - it beeps and all fine. Set the reversing position - press M then press adjuster again quickly - stored. Works fine an indeterminate number of times, then decides I must be bored with the view & shows me somewhere else instead. When it does this, if I press & hold the 1 on the seat memory, it realises the error of its ways & goes back to where it should be. It has the "auto fold on lock" enabled and I've seen much mention of wires breaking, but I'd be grateful to anyone who has seen (& solved) similar if they would enlighten me as to what is going wrong.
