Ibs error intelligent battery sensor

[Danishp97]

Hi guys, I had a new battery installed from the dealership 2 months back, battery state of charge on bimmerlink shows 99 %. However whenever I scan the car i get lots of weird codes. When I clear it all go away but the IBS code stays. The other day I started the car and I got the increased battery discharge when stationary message on the idrive. Scanned with bimmerlink the following codes show up -

00 Junction box electronics
3 errors
8020DB: Battery sensor, WakeUp line (WUP): Short circuit to ground or line break 8020E8: Terminal 30F reset / shutdown

9307BA: One or more DAYS blocked due to game protection
56 Roof function centre

DE8C5E: LIN Sine, communication failure 801A52: SINE: Coding data write error

Upon clearing all codes all codes go away but the CD8F01 code stays. Anyone in here??

On the negative battery terminal is the IBS. There is an elector a connector on it, make sure it’s plugged in and not damaged. The tech installing the battery may have unplugged or damaged it.
