Not sure where that info comes from Alister but the wire colour codes mentioned do not relate to those of the VSS (speed sensor) on the M3W
Sorry both, I made a mistake and swapped the colours this needs to be: YR and YK.
@Richard, with checking the bobtail, do you mean the Y-K-YW-YK bomb tail?
I will first do more extended test riding with the VSS disconnected to ensure that all normally work without speed input. And also want to get my joy back with a normal behaving M3W because only searching for a solution without any progress kills my happiness in the car.
But again, I appreciate all help and suggestions from all to solve this annoying problem.
