Hello, I’ve had a car for a few weeks now. Basically a nice car, however, the inaccurate indication of the kilometers up to refueling is annoying. Under a consumption of 7-7.5 li it is initially indicated that up to 610km would be possible. However, the kilometers fall significantly over the amount of consumption. When refueling the vehicle (refuel when lighting up the indicator, about 40km) however, instead of just 50li (capacity ) only 38 li. Returns the rest of 12 Li. What with above consumption would be over 100km and not the mentioned 40km through the vehicle. Have read and heard about a buffer, however, that seems to me a lot of buffer. A car dealership says that this must be so, another car dealership says that the system is simply sluggish and I should save the kilometers every time after refueling. What now? Thank you for your help.
