Our MS died. The car is in our garage. Wife was supposed to go to the work, but couldn't get the car going. It showed a message "Unable to start" on screen, followed by "Vehicle may not restart". The same messages are viewed on the app: After that, MCU went blank and indeed does not restart. I have tried reseting with the steering wheel buttons, it does not wake up. Car seems to have working +12V, because I can open frunk, trunk and central locking normally, and brake lights light up when I press the brake pedal.. Charging port opens from the keyfob, but the cable can't be inserted as the lock does not unlatch. So basically it seems only MCU is dead? Is there some MCU fuse that I could pull, to try "force reset" the MCU? Car is a 2013 P85+, with MCU2 retrofitted a few months ago! So it's not MCU1 emmc issue.
