Hello, since last year I bought a Kia Cee’d (built in 2013) and had it retrofitted with a Prins (with additive supply) gas drive. So far everything goes well. However, there are 3 things that disturb me: 1.) The engine control light goes on and off arbitrarily. I heard that it lights up all the time with some. But in irregular stops on and on, is that normal? 2.) The display of the “km how far I can still drive until I should refuel”. In the end there are “—— km” on the display and the petrol tank is still half full. 3.) I get off and when the gas drive is off. This ! lights up permanently. Tank is full and additive is still available. What can be the reason. Statement of my workshop: This is all normal, I would still be privigilated. In others the engine control light would shine permanently and the mentioned display would not work at all. What do you say, is this really like this or is talking to yourself d He workshop here only out. Would for example another ECU help? From my lay-like point of view, should the display show how far I come with petrol + gas or? To 3. I still have to go to the workshop, but would like to hear your opinion first. Thank you in advance for your help.
