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
