    Hello

    I’ve 2009 International Durastar 4300 Dt 466 Maxxforce . Problems I’m having with my Solid yellow PDF light.
    Comes on after driving the truck fir 20-40 min on the highway or city roads, and won’t turn off until I shut the truck off. Then the cycle continues 20-40 min driving back on and won’t turn off until I turn the truck off. Also it’s in Regen mode while the solid light is on. I tried to to Parked Regen and no luck . Any advice?
    Thanks for reading

    You either have a clogged filter or bad sensors. A regen is triggered when the ECM senses that the filters are getting full. I'm surprised it hasn't shut you down yet.

    Could also be a clogged EGR as well. Thats what was wrong with mine when it gave me the red dot of death.

    Thanks for some information. I don’t have any trouble codes , after restart of the truck everything is perfect for 30-45 min when the light come on . Even with the light solid yellow on power is good just at the beginning you feel regenation mode on. If the Dpf filter was plug wouldn’t restart make no changes?

    Well said.. EGR problems can appear like something more serious. Make sure your EGR valve is clean and working properly.
