BMW E60 battery replacement and registration
525i535d
Does a new battery have to be registered to the E60?
Yes. BMW's service bulletin requires registering a new battery. Registration resets the battery history stored by the car, so that charging is sized for the new battery. Without it, incorrect messages can appear and charging can stay incomplete.
Which battery sizes can be coded to the E60?
The coding options are 80, 90 and 110 Ah for a conventional battery and 80 and 90 Ah for an AGM battery. There is no 100 Ah option. If the battery size or type (conventional/AGM) changes, the change is coded into the car and the battery replacement is registered afterwards.
Does the battery need coding if the cables are only disconnected?
If the same battery is refitted, no programming is needed. For active steering to work, the steering wheel is turned lock to lock, and the clock and date must be set again.
