There also was a post how taking the dpf apart and knocking holes threw it too alleviate any back pressure so there would be no more regen cycles. Drawback from that was there will be exhaust smoke instead of clean exhaust. I imagine eliminating the dpf would be the same. With the XR3140h, the regen is every 50 hours like clockwork.
GolfTDI1. DPF was replaced less than 20k miles ago under warranty with EGR filter. Several thousand miles later, wire harness for exhaust temp sensor #4 was damaged setting a code for the sensor and preventing active regen of DPF with MIL. Took me a little while to get this fixed. Before getting fixed, exhaust flap intermittant failure, then
Problem with gutting the DPF is that when the ECU tries to execute a regeneration cycle with nothing there it never brings the temperature up to burn out the soot. Meanwhile the ECU is dumping raw diesel down the exhaust in attempt to light the DPF on fire. The fault code appears not so much because the DPF is gutted but because the regen failed.
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.
The stealership replaced the thermostat and 'conjuction' for $1200, and now say they cannot regen the dpf and it needs replacement (they did not obviously drive to induce regen). I haven't driven with my DPF warning for more than 100 miles for sure (before the visit to the stealership). I am wondering if it is worth trying to regen the dpf myself.
If you take your 6.7 Cummins to a dealer for a DPF regeneration, they usually change the engine oil once the DPF filters have been cleaned. Like the dealer regen, you should change your oil after performing a manual regeneration to your 6.7 Cummins. The engine is usually subjected to extremely high temperatures during the regen process.
The ECM uses the following criteria to perform a regeneration: Vehicle in Drive. BARO sensor 1 is more than 51 kPa (7.4 PSI) Engine speed between 500 and 4000 RPM. Exhaust Gas Temperature Sensor 1 between 100 and 725 C. Exhaust Gas Temperature Sensor 2 between 95 and 750 C.

My Sprinter did a regen cycle after I reached the summit of a long mountain climb. I watched the DPF temp climb from 750^ to 1200^ in a matter of seconds. About 10 minutes later it was back to "normal" in the 500^ range. I also like to know whats going on. The Scangauge2 is a good product.
What is DPF Regeneration? Every filter, regardless of what it is designed to trap, will have to be cleaned and emptied on a regular basis so that there is space to continue trapping more things. This process of cleaning and emptying a Diesel Particulate Filter is called DPF regeneration. The soot created by the process of combustion which is
As a side-note: Whenever going through all the trouble of removing the DPF for cleaning, it’s a good idea to get the DOC (Diesel Oxygenation Catalyst = catalytic converter) cleaned at the same time. This is a good practice because soot can buildup on the face of the DOC substrate and also restrict exhaust gas flow.
The forced regeneration process can take up to 30 minutes. DPFs require more maintenance than catalytic converters. The ash from the engine oil accumulates on the inner walls of the ceramic and in the pores. This increases the pressures in the DPF and if clogged, can even damage the engine. Therefore, the regenerative capability of the DPF is
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
DPF regeneration is the process of eliminating soot particles accumulated in the diesel particulate filter, either through active regeneration, passive regeneration, or a combination of both. Active regeneration involves increasing the exhaust temperature to burn off the soot particles, while passive regeneration occurs when the exhaust
There are two types of passive regen methods. One is “forced DPF regen,” and the other is “parked DPF regen.” But in this case, you need to perform the forced DPF regen. Let’s see a better view: Forced DPF Regen. You start a forced regeneration with the help of a diagnostic scan to begin the regeneration process.
