RFQT wonít pass
The warranty has timed out and the problems are getting costly, had the truck intothe dealer for ďservice emission systemĒ flashing on the DIC, and the check engine light on and now in limp mode, the code was P2202 nox sensor #1, the dealer changed it out and ran a regenthen areductantfluid test RFQT and it wouldnít pass, so the tech changed nox sensor #2, did another RFQT and it still didnít pass, then did a second regen, so now they want to replace theDPF because they say itís plugged, my question to the tech was, why didnít tech2 show that on the first diagnosis, he said he couldnít because there was no fault code for that, so, Iím thinking they are just pushing parts on me, or are they correct when they say they couldníttell the DPF is plugged? The truck ran fine lots of power asusual, 125000km on it 2/3 of that is highway driving, so the regens were happening, as the tech2 showed there was one done about 300km beforeI took it in, they also changed out the DEF fluid to be sure it wasnít expired, but I had put 20 litres in before the last trip. Iím not convinced itís a plugged filter, anyone know what else could be keeping the RFQT from passing? Thanks.
