Hello everyone. My car is a 2011 model with a 1.6 THP engine. I bought it three years ago. Since the day I bought it, the trip computer has consistently shown 2000 km. After a short drive, it shows - - - instead of 2000 km. The average fuel consumption also appears when I first start moving, but after a short drive, it also changes to - - -. However, I can always see the average fuel consumption on the multimedia screen I installed in the car. What could be the problem? I would be very grateful if anyone has any ideas. Have a good day.
