95% of people don't know anything about DPFs and regen (I didn't before owning a diesel) and most of them also don't notice the car is even regenerating or needs to until they get a clogged DPF from doing 2 mile trips to work for years on end.
I love having the gauge in the instrument cluster that show the level of the DPF, as well as when it is actively in regen mode. I watched the first couple regen cycles and it happened to kick off when I expected, the filter was about half capacity, and I had hit the highway and held speed for about 15 minutes when it started regen. 20 or so
How Long Does a Parked Regen Take? The duration of a parked regen can vary based on several factors, including the size and condition of the DPF, engine efficiency, and soot buildup. A parked regen takes approximately 20 to 40 minutes to complete. Factors Influencing Parked Regen Duration: Let us discuss the factors influencing parked regen
In either case, the system is designed to "pause" and "resume" if you should put the truck in park or shut it off, however this back and forth process can sometimes lead to excessive regeneration attempts, multiple failed attempts, or inevitably a DPF that fills up, requiring trips to the dealer for "stationary de-soot" or "parked regenerations
A passive regen is where the trucks operation in itself is enough to allow the soot to be burned out of the filter. An active regen is where extra fuel is needed to create temperatures high enough to actively burn the soot out of the filter. And then a stationary regen, also called a service regen, parked regen, etc, is not a normal form of regen.
This process will take 20-60 minutes and will use about half of the engine’s fuel. You can also hear a faint whistling sound. How Long Does DPF Regen Take? In order to keep emissions at safe levels and maximize fuel efficiency, a truck must be regularly regen its diesel particulate filter (DPF).

DPF light means and what to do when it appears. This should prevent unnecessary repeat visits for regeneration purposes. I have also found that as the car gets older, some 30K+ miles, you will notice that the regeneration takes place more often. ALWAYS, check your oil before any long journey, as DPF regeneration can use a fair bit of oil.

It got to about 1/2 and check engine light came on and went into regen. Immediately after gauge showed zero and engine light went out, but within a few miles it’s starting to creep up. I think I have a problem. I think it would be better if the light was still on when I take it to the p.o.s dealer.

Active removal of soot through on-board regeneration can occur one or more times a day, depending on its type of operation, manufacturers say. This is done by removing the DPF from the truck

Before discussing how Regen works, there are a few things you will need to know: Soot is a byproduct of unburnt fuel, it is also called "particulate matter". DPF Diesel Particulate Filter, traps soot in the exhaust. Regen The process of burning off accumulated soot in the DPF. The soot is converted to ash. back-pressure (restriction) fall back to normal levels. In order. to help you know the status of. DPF Regeneration, the device. will display an “R” in the “Alert. Indicator” section of the screen. anytime active regeneration is. happening. When my truck is in regen, it seems to be 15 or so miles of driving. After reading quite a few threads on the regen frequency of the 08' 6.4L trucks I have now noticed that I my truck hasnt performed a regen, or I havent noticed it
Today I successfully completed a manual regen while my truck was at my house, pretty impressive and scary at the same time. My engine cranked up to 2500 rpm and went to town fixing my emissions control system. Shortly after completion, I went for a ride and I had restored power. Current Truck: 2024 GMC Sierra Denali 2500 HD with retrax-pro
The vehicle operator must set the park brake and enable the parked regeneration to begin. Engine rpm increases and raw fuel is injected into the exhaust gas at the exit of the engine to generate the appropriate regeneration temperatures. The stationary vehicle manual regeneration processes take about 30 minutes. fSiX8kf.
