If it's really cold that can happen as the truck doesn't use much def if any at all, so it calibrates based on that usage rate and shows you insane mileage. Mine was like that, then when it warmed up it went back to like 8000 km range. There are a ton of sensors on that thing so if something is out, the truck will tell you.

Yes that’s what I’m thinking about, I work on semi trucks every day and when kind of problems appear some time it’s a def doser problem or egr related. Thank for the reply
