iDrive update last week and now battery problems
So, my car was in to have one of the side view mirror modules replaced and I asked them to update the iDrive as I haven't received an OTA update since 07/2020.
The work was done on Monday... on Wednesday I started getting a "Battery Malfunction" and "Power Supply" error when opening the car. I checked the battery with a voltmeter and it reads just over 13V, with the car on or off. BimmerLink says the batter is at 93%... whatever that means. It starts just fine and doesn't act funny. If I go on a longer drive the warning message won't come on the next time I start the car... unless it sits overnight - then it will come on in the morning. So... What happened here? 1- Car wasn't on a battery tender while the iDrive was being updated and now the battery is jacked? 2- The iDrive update has introduced some sort of battery drain? I've got an appointment next week... Here's hoping this doesn't turn into a chasing parts kind of problem. |

Checking in… the error went away after a week or so, but now it's back.
Guess I shouldn't have cancelled my appointment. This is all I'm getting in Bimmerlink: |

another option is to reregister the battery. error code detail description: The diagnosis monitors the software of the battery electronics in the lithium ion battery. The fault is entered if the battery electronics were reset. service plan for the code: If the fault is currently present or the fault frequency is greater than 35.
