I have kind of similar problem . After a two month a car was siting it was cranking a litle ruff when i came and buy a new agm battery then i noticed for a moment i cant open a window 5 mins all where fine then i cant lock the car sometimes the problem fixed by itself after a wihle my key wasnt able to unlock the car i paired it again but when i tryed tolock unlock sometimes corner lights wasnt working . After that came airbag problem later a abs and traction contorl. Then i was scared what is happening here went to mechanic and he sed i cant do nothing i cant conect to any modele in the body class. After that i came home and removed the carpet it was kind of wet then fixed the holes near back of the window and engine cpu water was coming over. And then i instaled impa instumental cluster showed k-bus short l IKI-EEPROM-Fehler, Codierung fehlerhaft/unvollstaendig Lichtmodul-EEPROM-Fehler then i picked yellow red white wire from rain sensor and cheked the ground yes its grounded to car with 40omh and after that i diskonected each module from the car but nothing helped after i checked x939 box there was i-bus wires and 2 of 6 was shorted a riped them apart and taped them. And now i still diging and trying to find any clue. Tomorow ill take all carpets and try dig deeper. Any advice?
Local battery shop R&R my battery. Immediately not working: instrument cluster (OUCH), conv top, AC isn't cold but blows. Dealer wants to replace inst cluster ...3800.00 The three fuses for inst cluster are fine. Are there other fuses that aren't in the fuse panel, that may have blown to cause all this mess.

I have a problem with my 530i and I need help please 🙏
How did you end up fixing it? Im having similar issues with my car as well. Did you have to replace the wires behind the radio or what?
This is exactly what is going on with my 03 E46 M3 Convertible. Do I just have to replace the KBus?
