just noticed this recently happening to my car.

trip A was on like 900km or whatever, and trip B was on 800 or so. I went to reset B by holding down the select button for 3 seconds, that worked just as I wanted. Then later that day, when B got to about 50km travelled, I was flicking through when I noticed that A had travelled 10km. I did not refuel during this time, or go into the settings.

So just wondering, how could this have happened? How does the auto reset on refuel mechanism work, I guess when the fueltank is opened (just wondering since maybe something else I'm doing is triggering it to think i'm refuelling)?

I've gone into the menu and set all options to default, hopefully it wont happen again, but anybody got any ideas?
