I sorted my problem. Part user error, part too much techy stuff.
First the mirrors. In amongst all the buttons on the driver's door is a button that controls the mirrors. Will lock them closed, will retract them to pass obstructions or will keep them permanently out. My local dealers said that they get one owner per fortnight who struggles with this button. It isn't very clear in the handbook, and sales guys never explain it. Have a look see in the little cluster; you might be surprised at what can be done!!!
Then the i-start. That's a total PIA. Again, according to the dealer there are 13 micro processors that have an impact on i-start. if one of these says no then it doesn't work. The main one is battery level. I-start won't cut in if battery is less than 75% charged. Don't think that a long run will sort it. If you have radio, air con, lights etc on the battery won't be charged enough. I've known it work/not work at junctions 100 yards apart. Best advice from dealer was to ignore what seems to be, but isn't a problem. They reckon the whole system is too complicated.
