Jeg føler det er nærliggende å tro, dette står i Rheingold/ISTA, som er BMW sitt service system.
"If the service function ”Register battery change” is not run after changing the battery, the data stored in the power management will not be reset. The battery quality will then correspond to an older battery. The value for the battery quality is insufficient for the battery installed. The battery charge state may then be misinterpreted and unnecessary Check-Control messages may appear or fault memory entries may be stored (e.g. the Check-Control message ”Recharge battery” even though the battery fitted is new and fully charged)."
