So I got a dpf particle filter replacement warning and I checked the soot (0%) and ash (62g) . I removed it and did the power wash and chemical clean which made no difference when I refitted it.I have just bought a new autel scan tool as I picked up a new DPF to fit . I said I’d try another forced regen and it made no difference so I saw it allowed you to set a new fitted DPF.i set that before I fitted the new one as it shows in the code that my warning looked like a 250,000km flag regardless of condition.
warnings now gone, and no soot or ash so maybe I can return the new DPF

anyone any insight or experience with these

cheers
