Quick Google search reckons its a battery drain issue.

Cause: Kombi fault at A559 terminal 30G-F switched off due to UNFAVOURABLE DRIVING PROFILE. ie. not driving long enough for the battery to charge.

that's what I've found online

Get a battery charger or go for a long long drive.

It may refer to the IBS reporting a low battery SOC (State of Charge) to the DME. The DME and IBS then shut down one of the load centers ("hotel" loads) to ensure sufficient voltage is available for starting the engine. I'm more familiar with the E60, but I believe the E9x has a similar power distribution scheme.

Correct.

I would also check the fault code entry time. It could have been stored from a long time ago. If there are no present issues, I would clear it and not look into it any further. BMW control units throw faults all the time for a number of different reason. If the car doesn't specifically show errors in the cluster or iDrive, in most cases you do not need to troubleshoot further.

How do you correlate the error code time stamp to actual date and time: example: 20280D5D7E02
