What is the process of regening a truck?
The process of regening a truck is largely automated, and much of the regen process is performed on the road. In order to maintain the health of your vehicle, you should drive it properly. The computer system in your truck is responsible for controlling the regeneration process.
How many regens do I need on my truck?
Unfortunately, there is no predefined number of regens to be expected. Depending on the maintenance and upkeep of the truck, there may be less regens required with proper maintenance and attention to your truck, or if the engine is underperforming and a continually ‘dirty-exhaust,’ many regens may be required.
What does a Regen sound like on a motorcycle?
“You’ll notice a reduction in power during a regen,” notes Nace. “You can sometimes hear a ‘hissing’ type noise, or a different sound from the engine.”
How do DPF regens work?
When soot levels get high, the regeneration burns it out. There are 2 basic types of regens, Active or Passive. Passive means that no fuel is injected into the exhaust system to add the heat needed to regenerate the DPF.
How often does a truck need to Regen?
Depending on your driving, active regeneration may happen as often as once a day. If you do a lot of stop and go, it can happen even more often. Frequency depends on duty cycle and how much soot collects – as often as once a day or every other day An active regeneration could take up to one-half hour or more.
How do you know if your truck needs a regen?
If your Check Engine light comes on while the DPF status light is flashing, it means you need to perform a parked regen right away. You may also hear a beeping sound to further alert you.
What will happens if you don't Regen a truck?
Regeneration, or regen, of the DPF filter, is the process that burns the soot accumulation that is inside the DPF filter. If you can no longer start a regen then you will eventually get stuck in a derate which will then lead to an engine shut down.
What is Regen on a diesel truck?
REGEN stands for Regeneration. the process by which the soot within a diesel particulate filter (DPF) is converted to ash through the use of heat, chemical reaction and or electricity.
Can I regen while driving?
Your truck can undergo the regen process properly while running, and will in fact, usually do so. Your diesel particulate filter, or DPF, undergoes routine passive regen as needed during steady driving. What is this? Active regeneration also occurs and happens best during highway driving speeds.
How much does a forced Regen cost?
between $300-$700A forced regeneration can be performed by any service shop with the appropriate diagnostic software. The cost for a forced regeneration varies. Generally, it is between $300-$700 depending on the technician's required diagnostic time and the length of time your DPF regeneration lasts.
Why is my truck asking for a regen?
A forced regen occurs when soot builds up inside the diesel particulate filter (DPF) to the point that the vehicle is no longer operable. When this happens, a driver has to pull over and initiate a self-cleaning process that can take up to 40 minutes — valuable time that could have been spent on the road.
How long does it take a truck to Regen?

Why is my truck asking for a regen so often?
The most common reason your truck regenerates is a clogged DPF filter which becomes clogged because of too much soot. When the filter becomes clogged, the ECU will activate regeneration to clean it up. You can also initiate regeneration with an auto tool, or clean it yourself using special additives or cleaners.
Will a truck regen while idling?
That burn-off, which is also called a regen, typically takes around 20 to 30 minutes when done regularly but can take up to 40 minutes if the vehicle has experienced a lot of idling. Pressure drives regens.
How often does a diesel engine regenerate?
every 300 milesActive regeneration will be initiated every 300 miles or so depending on how you use your car and will take 5 to 10 minutes to complete. But it's a problem if your journey's too short and the regeneration doesn't finish. During active regeneration you may notice: Cooling fans running.
What happens during a parked regen?

And you start the regen by hitting a button on the dash.
What is active regeneration?
An active regeneration means that a fuel dosing valve injects fuel into the exhaust system to raise the temperature. An active regeneration can be automatic or driver initiated. The engine will always try to do it automatically, but if it cannot, a light will come on giving warning that a regen is due.
What happens when you park a car and the exhaust starts to get clogged?
The exhaust filter starts to get clogged. So the motor needs to burn out the soot. Usually with a lot of highway driving and little idling the engine does itself while driving. However with a lot of idle or city driving it builds up and usually there is a light on the dash that tells you it needs to do a parked regen. That means you park hit a button and the engine revs up gets the exhaust really hot and burns it out.
What is a DPF regen?
First time diesel owners often think there is something wrong with their trucks, but the DPF regen is a normal, often recurring, requirement included with diesel ownership. A forced regeneration cycle is a manual process that takes place at the diesel shop with a certified technician initiating the cleaning of the DPF.
What is forced regeneration?
A forced regeneration cycle is a manual process that takes place at the diesel shop with a certified technician initiating the cleaning of the DPF. “We force the truck’s computer to initiate the process prior to the parameter requests that happen with the active regen,” says Nace. “These circumstances happen when the owner/technician recommends a regen prior to the automated process. If something happens that indicates a necessity, or to simply avoid the process while driving, we can override the system to regen.”
What Are DPF Regeneration Cycles?
An active regen cycle is a normal process that takes place as the truck is going down the road. A computer sensor monitors the DPF and a dashboard indicator light notifies the driver that the regen is taking place, or the DPF is now cleaning. “You’ll notice a reduction in power during a regen,” notes Nace. “You can sometimes hear a ‘hissing’ type noise, or a different sound from the engine.” First time diesel owners often think there is something wrong with their trucks, but the DPF regen is a normal, often recurring, requirement included with diesel ownership.
How Long Does It Take for DPF to Regenerate?
Unfortunately, there is no predefined number of regens to be expected. Depending on the maintenance and upkeep of the truck, there may be less regens required with proper maintenance and attention to your truck’s general upkeep. If the engine is underperforming and a continual dirty exhaust is occurring, then many regens may be required. Multiple regen cycles can happen per day if a truck is in heavy operations. And with multiple regens come mounting costs and interruptions in daily use.
What happens if a DPF regen cycle is not taking place?
If the DPF regen cycle is not taking place, or not completing a full cycle, a check engine light might illuminate on your dash. In doing so the many sensors in the system will calculate the particulates prior to the DPF and post, recognizing a lack in the operation of the DPF. “With the accuracy in modern computerization and the rigs that control that whole system, it’s something you want to pay attention to and address relatively soon before you enter ‘limp mode’ or ‘De-rate’ where the truck will not operate over 20 to 30 mph in some cases.”
What does it mean when your truck is choked down?
“When the engine is being choked down with a clogged filter, the driver may recognize just a lack in performance, throttle response, and power ,” says Kyle.
What is DPF Regen?
the process by which the soot within a diesel particulate filter (DPF) is converted to ash through the use of heat, chemical reaction and or electricity. Soot combustion temperatures range from the 250˚C – 350˚C range (with a chemical or fuel catalyst) to the 550˚C range (without catalyst).
Can a truck be regen while driving?
Trucks that utilize passive-active regeneration are able to both regen on the truck while driving down the road AND through forced regen initiated by the driver. Forced regen is required – let’s say – after the driver has sat in traffic for an extended amount of time and the “service DPF” light comes on…. this means the duty cycle isn’t hot enough for regeneration while driving down the road, so it’s prompting for the driver to manually initiate regen.
