Hi everybody, I did the upgrade from 520i to 525i, almost everything is perfect( the 525i was US import), but i have some problems with the board computer. The fuel consumption average is not working and of course and the rest distance to go with the fuel in the tank , is not working.The fuel indicator is going "" when it will touch the 1/4 position (the orange light indicates, etc), I don't know if it relative to the other indicators. Is it possible to be responsible the floter in the tank or it has to do with the central processor?
