1. Forced long regeneration of DPF (performed by Mazda personnel) 2. Checked all Diesel fuel injectors (all worked fine) 3. Used several additives cleaning DPF ( DPF ware factor reported by Mazda software is about 7% - excellent) none of the above worked.

Ram Year. 2020. Engine. 6.7 liter diesel. My 2020 2500 went into a regen that told me to stay on the freeway. 10 minutes later it lit the engine light, put the truck into limp mode, and said to take it to the regens. The DPF gauge said 100% full. The dealer changed out all the fuel and air filters and ran two manual regens. Asked on 11 January 2015 by brisca. Answered by Honest John. If you mean the old model Mazda 3 then there were some issues with the DPFs of the diesels, so better to settle for the 1.6 petrol. Tags: diesel particulate filter buying a used car reliability.

In other words the higher the differential the faster it goes up the scale. That could explain way Milkman is at 29 at 130 miles and I'm at 22 at 100 miles. I have also noticed that the differential pressure reading goes in increments of about .14. So if you are at .15 the next step is .29 then .44 and so on.

I am having issues with my touran doing a full regeneration and completing and then 30/40 miles later needing to regen again. It even happens on the motorway straight after a regen finishes another starts. So an update, I have today monitored with Vagcom and soot mass Cal gets up to 6.40g and then goes to 24.40 instantly.
