Sometimes I fuel up with the epower system turned on…. I’ve not had a problem yet🤷🏻♂️
And this is always the case with me - if I refuel with the E-Power system turned on, the remaining mileage does not change (that is, it remains the same as before refueling), but at the same time the fuel indicators are shown absolutely correctly, that is, the car "sees" that fuel has been filled. It is interesting that if you refuel like this constantly, the remaining mileage will decrease to zero, despite the fact that the fuel indicators are normal and correspond to the actual ones. But when I refueled after that with the E-Power system turned off, the car recalculated everything and everything became correct.
I checked, it always works like this for me, that is, I understand that it is normal for my car. I think it is connected with some kind of control unit, such is its work algorithm. Write, maybe someone else has it. I think only the Manufacturer can tell what it really is, but my Dealer doesn't know anything about it, unfortunately.
