@mysmartdecision: Not every DPF needs to be replaced. But some are DONE. Soot restriction and ash load are two different things. • Within spec? It can be serviced. • High ash load? Remove or replace. • Cracked or melted core? Replace. Diagnostics determine the repair — not guesses. If you’re dealing with constant regens or high differential pressure, get it checked the right way. 📍 Atlanta, GA 📞 (404) 228-2371 DM “DPF” for pricing. #DPFService #DPFProblems #DieselRepair #Freightliner #DetroitDiesel
