"Battery Management" message

[Alan Sirota]

On my 2024 540i video screen I was getting the following message every few days: " Battery Management. Start Engine. Malfunction shutting down the vehicle electronics when vehicle is stationary" The service department kept the vehicle for 2 days but could not diagnose or reproduce the problem. After a software update, the problem disappeared. Now it is back. I cannot discern any pattern as to when it occurs.

Any ideas? Should Service Department be able to diagnose without reproducing the message? Could there be some harm being done to my vehicle?

Thanks

Morning Alan

Welcome to the Forum

I find it hard to believe that a Main Dealer responded in that way, the car records ALL faults and their equipment should show it as a fault Present or fault Not Present? You don't want to compromise your Warranty however you could try a different Main Dealer. I would write to the Dealer MD a copy to the service manager and BMW UK Customer Service stating the facts of their investigation and efforts to fix it that have failed, point out that the car in it's current state is "unsuitable for purpose" and ask for a detailed course of action and time scale to resolve the issue.

Good Luck
