2012 Freightliner Cascadia dd15 has not used any def with last three tanks of fuel. The truck has not thrown any codes and is not derated. Any ideas?
No def consumption

Gauge not working? Unless there was some kind of a delete done there should be all kinds of faults and warning lights going off if it hasn't used any DEF.

DOC is located between engine and dpf. So no way to damage it.Last edited: Oct 20, 2018

This exact thing happened to me in a Volvo... About 4 days after it quit using def it finally derated me and threw a bunch of codes. The power wire to the aftertreatment control module broke.
