The above signs spin. The car is now 4 months old. I was suspected that it might have to do with the heater that I had started now. But the error now also occurs without a heater. When the car is turned on, the average consumption indicator jumps immediately to 30 – 50 liters, no matter whether the car is warm or cold. After that it goes down slowly, depending on the kilometers driven, it can also run back into the realistic area. Is such a mistake known….Software should actually be on the stand.
