Had a look on the internet and saw a similar problem with an 1199, on that thread it suggested turning ignition on/off quickly 5 or six times as that would soft reset the ECU and it worked for that guy so tried that this morning, still the same. Also the starter wouldn't kick over unless the side stand was up.....
Had the bike out in the sun while I fitted some R&G fork protectors and cotton reels. Put the key in a short time later and everything started as up as it should, no warning lights and the gear indicator showing N again. It also fired up no problems with the stand down.
Not sure what the problem was, but will be contacting the dealer tomorrow to get it checked out. May also ale her for a spin this afternoon too, just to check she's running OK now.
