Why do you keep starting a new thread on the same topic ? This must be the third or forth one started, stick to one thread and keep all the info in one place as you will find the replies won't come because people get fed up with going around in the same circles all the time.
We have told you already no one can repair the Bosh battery as it uses CANbus, if the electronics /BMS are faulty then the battery pack (if found to be good) can be stripped out and used on a bike that uses a generic hub or mid drive motor. The battery BMS would have to be removed and a generic one fitted then the battery can be charged with any generic charger.
Sell the bike for spares/repairs and by a reliable bike that doesn't use locked in components that even a dealer can't repair as the brand doesn't allow it.
