So I went to fill up, obviously I failed, its exactly as before. I'll take it out one last time to check in case it has moved but I doubt it.

Before filling up : 13,4L (didn't record each side's value)
After filling up :
52.2/ 22.6/ 74.8L

Is there somewhere in the BMW software where the gauge needs calibration? My thinking is the pump part is not original but the assembly is so maybe someone played with it.
