Advanced Onboard Battery Diagnostics

BMW technical service bulletin 610211 for 2012-2014 BMW 328I, 2011-2014 BMW X3 and 2011-2014 BMW 528I and others.

Bulletin number: 610211
Component: Electrical system
Summary: Advanced Onboard Battery Diagnostics. Starting with the introduction of the F10 (5 Series), an advanced intelligent battery sensor has been used. This now makes it possible for the vehicle to monitor the condition of the battery in order to determine if the battery needs to be recharged or replaced, along with the remaining capacity of the battery. The analysis and testing of the battery's SoC (Stateof Charge) and SoH (State of Health) is now performed using ISTA (Integrated Service Technical Application) diagnosis. A separate test using a battery tester is no longer needed.

Owners of these vehicles have filed 445 complaints in the electrical category.
