Ibs error intelligent battery sensor
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 C90DBE: K-LIN_7 emblem: switch end stop 10 Central gateway module 2 errors 801C10: Request to reset terminal 30F alarm clock 801C11: Request to switch off terminal 30F alarm clock 12 Motor electronics 1 error CD8F01: LIN, communication (intelligent battery sensor): missing 3F Active sound design 1 error 8053A5: Invalid encoding data for Equalizing 40 Car access system 1 1 error 9307BA: One or more DAYS blocked due to game protection 56 Roof function centre 2 errors 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.
