But before condemning it, it will need to be checked.

If the DPF is not getting clean as it should, then the first thing to check would be the dosing injector. 5. Next the DPF traps soot. 6. During some truck operations the exhuast is hot enough to burn off soot while driving with no fuel sprayed through the 9th injector, this process is called Passive Regen. Passive regen is happening any time temperature in the DPF is above 800 deg F. 7. I drove 16.2 miles home today from work, Oxford Circus area to Enfield and see my mileage attached, also find my Trip A counter.
