In my Xceed I have, just like other owners of the same vehicle type, 3 consumption or average consumption indicators. 2 of them in the digital cockpit, 1 after you turn off the vehicle and turn off the engine. None of the 3 has a realistic display and comes in accordance with the calculated consumption, tanked liters x 100 : driven km. All 3 show different values with up to 0.6 liters deviation in both directions. Is there a possibility to adapt this display to calibrate or to calibrate?
