1) did a forced regen burn and DPF soot read ( 59% ). 2) a filter and oil change ( Penrite Enviro+ 5W30 ). Oil was well above high mark. I suggest you check this ASAP if you suspect DPF issues. 3) Then reset the oil service interval ( which cleared the flashing DPF light that had appeared a week prior ). In the stock form, the DPF (diesel particulate filter) would regenerate (what they call cleaning itself) every 100 miles or so, or depending on how full it thinks it gets. To do so, the truck automatically goes into regen mode, in which it injects a certain amount of fresh fuel on the exhaust stroke and sending it downstream to the DPF. Minnesota. Jan 23, 2022. #2. Not sure it is required at 50% but below is what you should do at 80%. Could be possible that nothing happens at 50% when you perform the below steps. Not sure. One section states: The Cummins® diesel engine meets all diesel emissions standards, resulting in one of the lowest emitting diesel engines ever produced Most cleaners will over bake and damage the filter. REASSEMBLY: The filter is re-assembled and painted; FINAL TEST: The DPF filter is flow tested a second time to ensure it was cleaned effectively and is over 99% to factory flow specs. DELIVERY: Lastly, the DPF filter and flow charts are shipped to your door and ready to install. in this video I will share with you how to clean a DPF on a Mercedes/Dodge Sprinter Using Liquid Molly DPF Cleaner#DPF #SOOTLEVELTOOHIGHINDPF #SOOT #REGEN The warranty book states that the recommended maintenance schedule is not affected as it relates to DPF ash loading, but it also specifically states that the DPF IS covered. 81,000 is far short of the recommended maintenance interval of 110,000, the first time it's to be checked.

Driving at 40mph or more for 10 minutes should prompt the DPF to go into ‘regeneration’ mode and burn off soot Failed DPF pressure sensor – This sensor measures soot levels before and after the DPF filter to determine the pressure drop within the DPF filter. This sensor senses the pressure be t ween t he DPF filter and notifies the ACM (Aftertreatment) or ECU (Engine Control Unit) the pressure difference. A failed sensor can provide false readings and J5FO.
