Display Range

Hi there, yesterday I got really angry about my car for the first time. I wanted to drive a distance of 90km. At the descent the rest width indicator said still 200km. Well, I thought, then I fill up after the highway (so after about 75km). That the range indicator is not quite linear (and that can’t be possible) is clear to me. But now the following happened: After 60km of leisurely drive the rest width indicator stands at 60km, jumps on 50km, then the car goes straight out , because tank empty. In the middle of the A7. The ADAC brings the saving canister, fortunately nothing happened and it jumped again with a little starter spray and now I hope that the pump did not suffer too much. It is clear to me that it is a certain risk to drive the car towards the reserve. Only if you are used to driving 1000km/week, you do not want to refuel all 400. However, all my previous cars always have it, even with residual range 0 still to the next Tan What a useless feature when something like this happens. Then it would be better if you didn’t have the fucking display, but the good analog needle that scares you to the right degree. How does your residual width display work? Best regards
