A bit long, you can edit the post only the last part is useful.
Have you tried to start it with clutch pedal pressed and Brake pedal pressed, the switchs on these if closed will not allow you to start.
Bizarre, Average regen 39Km!!! Is the FAP gone? regen only 210 sec? may be temp a bit on the low side but not sure. I cannot check with mine before another 2 weeks, i work on a yacht (Chief engineer) and I am in the Caribbean at the moment.
Have you tried with the physical key inside the keyfob directly in the little hole, this might by-pass security lock.
Could you do a log with the curves when you are actually trying to start the car and send me the excel files I have FES with me on my laptop:
With batterry voltage
actual fuel pressure (2.1 bar at the moment, this could indicate that the tank pump is priming)
Fuel pump relay
Try to log these you know on the GRAPH section do several trials and send me the excel files, I have sent you a PM with my address.
I will look at it as soon as I can.
