Note:

Disconnecting the battery clears all entries (such as 
errors, adaptations) from the BMS control unit mem-
ory.
The loss of the adaptations may sometimes lead to 
engine performance being temporarily impaired 
when the engine is restarted.
The BMS restores the lost adaptations itself over the 
following operating hours.
