Hello again a new problem. I just drove with the child to the Baltic Sea and wanted to see how many km that were. Now I put the bc on the display “from start” and it shows me almost the km that I have driven since the last tanking It seems to me that these are the km that I have driven since Friday after work until today. Only the dare stood the whole Saturday. I thought that he automatically sets himself to zero after a certain time window. Am also the Me and that it has always worked out so far. Has. One an idea what this could be now again GRUß Martin
