[QUOTE="Schwepps, post: 469522, member: 3592"] IMO, that only means it's a pretty accurate real-time system, AB. When you fill to full tank, the tank sensor detects that and displays the default value - max km with a full tank at the designated l/100km FC for your model. As you drive, your actual FC will probably be higher than that, and the default value will drop. This indicator cannot be based on the total average FC and should be based on the current FC since resetting, ie whenever the sensor moves up (gas pumped into the tank) This sort of programming is what I do for a living and this is how I would design the algorithm too. :wink: Earlier, I thought my front brake wear counter is stuck, but now it's started to drop and that matches with my recent discovery that only 25% of my front pads have been used after 42K km. There's probably a set-point before which the counter won't move. So now I feel that the brake wear counter is accurate too. :) [/QUOTE]
