Thanks for the replies guys, all helpful but unfortunately when it’s switched on the bikes orange triangle and ABS lights should also be on, they’re not, only thing lit is the neutral light, which goes out if in gear so the screen is then blank, it must complete the diagnostic check and only then can you start it, am convinced it’s the antenna ring around the ignition switch but when I visited the very friendly BMW dealer the technician noticed when I showed him the above photo said the fuel gauge is blank and said that makes him bet it’s the kill switch, went home and pulled it apart (make sure you have T8 Torx screwdrivers) the kill switch is simply a press and release switch like a door bell, to me it’s perfect, so am going back up to the dealer to see what else it could be, I initially thought in was the antenna ring but he said there was also something else near or around the switch that could be, that’s when I showed him the photo and he went for the kill switch, methinks the switch does 2 things at once, mechanically you turn it on with the key, it’s then that the ring reads the key to see that it’s the original key and not a copy then it sends a signal to the brain to start the diagnostic check, think it comes under EWS in the manual. All very interesting and frustrating, but hey thanks for getting involved
