Anyway, it pretty reliably starts the regeneration as soon as it hits 103% (and the van is warmed up). My 2012 works similarly. I bought it used over a year ago, and my DPF level would reach 112 to 116% and then start regeneration. It would regenerate "100%" down to 12 to 16%. the anti pollution systems on vehicles these days, are a little o.t.t in my opinion. I had engine management light come up on my peugoet and I ended up have 3 things replaced. the fuel additve pump,( because it stopped working} the nox sensor (because it couldn't read the emmissions any more) and a catalyst ( because it was cracked). total 2k. and thats with peugeot paying 25%. this is on a How Regeneration Should Occur The DPF traps the soot generated as a part of the normal operation of a diesel engine so that it is not sent into the environment. The process of regeneration enables the vehicle to clean the filter so it can trap more soot. Factors that determine when the ECM will try to perform a regeneration include: A typical regeneration process could take 20 to 45 minutes to clear out the DPF. The majority of fire apparatus built with EPA07 certified heavy-duty engines were equipped with a DPF. All fire apparatus built with EPA10 or later certified engines are equipped with a DPF. Any apparatus with a DPF will require regeneration. Regeneration Types on this video I will share with you how to force a stationary DPF Regeneration process using the Snapon Zeus Scanner #DPF REGENERATION #DPF Below are some of the issues that can trigger the P2002 code: DPF failure/damage; Exhaust leak; Excessive slow-speed or stop-and-go operation of the vehicle; Defective exhaust back pressure sensor; Constant short-distance trips and stop-and-go traffic limit the speed and temperature at which the DPF can regenerate. STEP 5: Start a forced DPF regen You need to start a forced DPF regen to ensure the regeneration system is working properly. N OTE: Some vehicles require a forced DPF regen for the fault codes related to the aftertreamtent system to go inactive. You must use an advanced diagnostic tool to perform a Forced DPF Regen. You can trigger a static dpf regeneration but you need to use diagnostic equipment to do this. If the dpf sensor is ok and the dpf is actually blocked it could be down to a faulty fuel vapouriser. This assists the regeneration process by raising the temperature of the dpf by squirting vapourisered fuel upstream of the dpf. If you need any RobbieA. Yes, mine does the same and it is normal. Frequency depends on type of driving - i.e town and traffic, short journeys from cold start will cause the DPF regeneration cycle to occur more often. Mine has only happend twice in 12k but mostly country driving. Yup, it puzzled me the first time too. Hello All, I have owned my 2016 Ram 2500 with the 6.7 Cummins for two years. Periodically, the dash will notify me that a DPF Regen is in process. It will start a countdown at 100% and then slowly tick down to 90%, 80%, 70%, 60% and then give me the "DPF Regen Complete" message. However, the last two times the DPF Regen has started at 100% and jMPzUYl.
