i think there is a way, i am sure i just saw it recently somewhere, i will dig around for you

i found this on focusfanatics

For a reset of the BMS:

1. Switch on ignition (do not start engine)
2. Switch on dipped beam
3. Press 5x the rear fog light button (do not switch 5x on and off the rear fog light)
4. Press 3x hazard lights button (do not switch 3x on and off hazard lights)
5. Then the battery symbol in the speedometer should flash 3x quickly.
If it does not flash immediately, wait 20 seconds.

i will have to check this and then double check using forscan if the days are set to 0
