Hello,
I may have spoken too fast.
After reading this link
https://bimmerscan.com/bmw-intellige...ry-sensor-ibs/
and particulary this :
"The current SoC/battery data is stored in the IBS every 2 hours over a 6 hour time frame, providing 3-2 hour snapshots of battery SoC information. The stored information/snap-shot data is overwritten every 6 hours. Whenever KL15 is activated the IBS updates the DME with the current closed circuit histogram/battery status information, by way of the BSD. Upon obtaining updated information the DME evaluates the new data and if a closed-circuit current draw is identified a fault will be stored in the fault memory of the DME."
I decided to give a try, and replug IBS and let the car rest over night (at least 6 hours).
When i took my car the next morning, no more battery drain message.
So I erased all INPA codes, and will report if it happens again.
