The DPF is basically a good system, but you must operate your diesel at higher rpm than most normally do, this to encourage automatic regens as you work. Consistent short time use of a tractor, at low rpm can quickly fill the DPF with particulates. So the harder you work your tractor, the better your DPF gets cleaned. Thanks. During the first 6000miles i got the EVIC message at least 4 or 5 times 'continue dtiving regen in progress'. In the last 2000 miles, since a 'reductant pressure too hi' CEL code and subsequent reflash tsb, i havent gotten the regen message and my def gauge hasnt moved at all. Regen helps reduce harmful emissions, improves fuel efficiency, and prevents potential issues with the diesel particulate filter (dpf) in your ram 2500. Conclusion. To sum up, regenerating the diesel particulate filter (dpf) on a ram 2500 is a crucial maintenance task to ensure optimal engine performance and fuel efficiency. A forced regen almost always pulls the soot level down to acceptable limits. The better way is looking at the history, times and temps of all the auto preformed regens. Oil consumption, faulty injectors, DOC not getting hot enough, burning coolant and faulty wiring to the dpf differential pressure sensor can all cause incomplete/ too frequent But, because DPFs, like any filter, only have a certain capacity the particulates/soot needs to be burned off to ‘regenerate’ the DPF. The regeneration process ‘cleanly’ burns off the First, some DPF maintenance basics. The active and passive regeneration process routinely burns off soot collected in the filter during the engine combustion process, which keeps clogging at bay. But the system may also require a forced regen while parked. If, in order to regen the filter, motor manufacturers need to increase the amount of fuel entering the exhaust system to burn off the soot then this in itself increases pollution and adds to the causes of global warming plus the carbon footprint of manufacturing DPF filters in the first place. DPF filter is a waste of time it does not reduce I noticed that my DPF filter was reading 95%. Opened Forscan and it said that the the filter was only at 37% full. Tried to do a manual static regen but Forscan would not let me because the values were to low. Went to my Ford Diesel mechanic and he was able to force a regen with the Ford software. After about 30 minutes the task was completed. 2LiHhi.
