More tests done. When I set a goal it reaches that goal and keeps the dashboard on (even when bike is turned off with the key). The cable isn't released until you turn the key to put the bike on. I'm pretty sure this is a change cause I used to get to my bike in the morning with a charge goal set to 90% and just unplug it and only later on when pushed outside of the garage I turn the key. Not a real issue, I can turn it on first, release the cable and the push it outside.
When set to charge to 100% it's slightly different. Then the dash is off once completed and when I turn the key to put the bike on it lights up with the override option. Cable not released yet. Turning the bike off and on again with the key finally released the cable. That seems a bit weird. Not a big issue since I rarely charge to 100%. And again I'm sure this is different since the update.
Also all off this is still different from that morning right after the firmware update. Then I tried turning the key several times and no cable was released. So at that time the bike was in a faulty state for sure. Something must have fixed it. Next week I'll test with a charge station.
From now on I keep torx bits with me and a socket No 10 just in case I need to reset it by removing the 12V battery. I have this compact set from wunderlich (yes from the BMW GS).
