Inaccurate fuel display Kia Rio 1.4

Now that I’ve filled up almost 2,000 kilometers with my 1.4-kilometre spirit gasoline tanker, I’ve noticed the following very negatively: As soon as the residual range display of my on-board computer has fallen below the 50-kilometre mark and shows only two strokes in the display, Pi also starts to light up the tank indicator and that, although at this time I just drove 380 – 400 kilometers. I have now had it escalated and the Rio filled up two lines under the lowest tank marking subjectively “empty”. Sweatingly arrived at the gas station, I then filled the Rio Press up to stop and just filled 34,5 !?! liters Super. According to Kia, the Rio has a tank volume of 43 liters, that would mean that the tank display already at 30% of the remaining content. jumps Is this normal and can you possibly adjust something like that? The float is fixed in the tank in m. W., you can not have a lot of play when you install it. How are your experience with the accuracy of the tank indicator and when do you usually refuel? After warning light or after level indicator? How many kilometers do you create with your 1.4 Spirit gasoline? Greeting, Clark
