2 check engine lights on and my DEF fuel light on but I just filled DEF tank

If it has an active emissions fault, it will not do a regen even if your have the software unless the fault is fixed.

 

" OCCASIONALLY", IF I fill a Def Tank till It accidentally "pools" at the lid. A Def light will stay on for about 6 hours.Did it go out?

 

I just payed 3000 for parts and labor changed both nox sensors and a two weeks later got all there lights on again plus my
Red exhaust light

 

Yes, I have had to do a Full DEF fill up and a few restart cycles and it reset itself… 100%… we’re all good!

 

Yes!

 

I was getting this code nothing was working I had to change the def line hose and it was all good
