ISSUE IS SOLVED!
Drove 140 km in wet conditions to my dealer yesterday and had the update (yes, I was keen to get it
).
He told me that the old version somehow managed the cell balancing suboptimally, which sometimes led to a depleted cell which in turn would cause the bike to stutter a high accelerations and to less than 100 % charging. Besides that some other issues were adressed with this update.
Arrived with 22 % SOC at home, put the bike on AC and it went to 100 %. Cooling fan stopped after charging as it should. Therefore I think the issue is solved.
As an aside: Maybe the issue with the 10 % error in velocity (GPS 100 km/h, display 110 km/h) was adressed as well. On my way back a had a difference of between 3-5 km/h only. But my GPS behaved a bit erratically, so I am not 100 % sure. Will take some time until I can move the bike again because it's raining and it's cold now. Plus I need to clean the bike (will take me days
)
But I will keep you posted.
