All series
Situation:
The electrical system of BMW vehicles has been subject to an ongoing development
process over the last few years. This has led to increased demands being placed on the
battery. This document summarises all important information about how the battery should
be handled in the dealership.
Procedure:
The complaint "flat battery" can have various causes, most of which do not concern the
battery itself. For this reason, replacing the battery will not usually lead to a lasting solution
to the problem. The cause must be properly analysed in order to perform a repair that
actually rectifies the cause.
Below you will find list of the available aids. These must be worked through step-by-step to
investigate the problem. The documents listed can be accessed via hotspots.
1.
Fault analysis (energy diagnosis)
Fundamentally, the following causes are possible for a
breakdown resulting from a flat battery or problems in
the vehicle's electrical power supply:
Vehicle faults
•
Battery defective / alternator fault
•
Vehicle does not go into sleep mode
•
Vehicle repeatedly "woken up"
•
Off-load current too high
Operating error
•
Side lights/parking lights/hazard warning lights left
on too long
•
Terminal R/15 left on too long
•
Unfavourable driving profile (e.g. extremely short
distances)
•
Unfavourable usage profile (e.g. excessively long
periods out of use)
For E65, E66, E67, from model year 03/2004 and for
E60, E61, E63, E64, E81, E82, E87, E90, E91, E92, E93,

through if the complaint "flat battery" is encountered.
