HI Laurens,
did you press the black button?
The "accident switch" could be activated after a strong ride or a "hit".
Just press it and find out if the M3W starts after it.
Sorry i have only a picture of the part from my ARP4 (my M3W is on service)
The black part with the soft surface in the middle of the picture - the same part in M3W...
Good luck - Thorsten
