Hi,
I'm working on DD15 with active code for DEF quality low.
Almost everything is replaced - Def dosser unit, air valve, both NOX sensors.
I tested the def dosing and quantity is OK.
During regeneration temperatures are in the limits and the NOX sensors as showing about 240-250 inlet and 240-280 outlet..
Do you guys have any idea what else I need to check to find the problem?
