The DPF is located in the exhaust of a diesel car. How often does a DPF regeneration occur? The DPF will usually regenerate when it’s around 45% full, but how long it takes to reach this level will depend on your driving style. If you regularly drive at over 40mph for 30-50 minutes, the DPF will stay clear anyway. 6. Reaction score. 0. Sep 3, 2021. #1. Hey all, Have a 2020 6.7 with 37k miles. About 10 days ago got a check engine light with code P2459- Frequent Regen. My truck had been running a Regen about every 25 miles. As soon as one would end another would start. 1/ Drive a lot and quickly and you may never see the DPF light. 2/ If you see the DPF light (I presume that is how Wayne knows when his ECU is trying to do a regen..), go for a fast-ish drive of at least 20min and if the light hasn't gone out after 30min, get a diagnosis with PP. WR. I took some time to talk about how often my truck is actually going into exhaust regeneration. Since I have the GM tools, it was easy for me to go into the e I'm wondering how often does your GTD do a DPF regen? I have a MK7 GTD with 120k km on it and it keeps doing regens every 250km or so (higher idle rpm and fans blowing, no dpf light though). Is that normal? I couldn't really find anything about GTD DPF, sorry if i didn't look hard enough. With other cars people said it's supposed to be 500+km. Particulate Filter Regeneration Stay Warm. By default, this feature should be enabled, but may be disabled on some buses. The DPF Regeneration Stay Warm feature allows the DPF to stay warm when, during an in-motion regeneration event, the vehicle speed drops below a specified threshold. When enabled, the engine will continue to provide additional 1551 posts · Joined 2012. #16 · Nov 4, 2014. I've been looking at my manual and it states that the DPF regeneration cycle occurs automatically every 190-560 miles. It takes 10-20 minutes if the car is driven at stable speeds of 40-70 mph. It can take longer if you drive at an average speed of 30 mph. Also look at 241.2 & 241.3, Soot Load Calculated & Measured (g) -- ideally, these should be close, but either over about 22 g predicts onset of an auto DPF regen. You'll know the regen is underway when temps in Group 099 (099.2 Temp Prior to Turbocharger, 099.3 Temp prior to Particulate Filter, and 099.4 Temp after Particulate Filter) are much
Got a truck doing a regen and dpf differential pressure is between .30 and .48. Is that normal or do I need to start looking into getting a new dpf fitler. cummins1 , Jun 24, 2019
