Need help…
I have this warning message everytime whenever open the door. The message disappears after engine start (no fault).

That basically means your 12V battery is low. The IBS system maintains it, but it is saying if you have heavy power devices running after shutdown they may be draining it more. It might also happen if the battery is aging too I'm sure.
If you are on an ICE car it could be an alternator issue or battery issue or IBS issue (like not coded to the battery size so not properly charging it). If on a PHEV I have had this happen in the cold if you didn't have a charge on the HV battery (the HV battery maintains the 12V as the PHEV lacks an alternator). |

I attached the documentation for the changes added in MY2020 and BMW notes it is largely unchanged (though they do mention some unspecified software tweaks) from MY2019-. It is from here on the forum. Somewhere. So I can't take credit for it. ST1928 G30 PHEV Update.pdf |
