If you keep driving your truck without doing a parked DPF regen your truck will enter a derated mode. When this occurs your engine power and/or your speed will be limited.
Failed regeneration usually means extra fuel is injected into the cylinders for active regeneration, which doesn't burn but instead drains into the sump. The results can be severe: loss of oil quality and a higher oil level. This may damage and even destroy the engine.
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.
A DPF Filter that is too full or not properly functioning threatens both the environment and the truck. The engine can derate when a needed regen does not occur, potentially causing downtime by leaving the vehicle in a state that is either undriveable or in “limp mode” where it can only operate at slow speeds.
We'll now wait 10-30 minutes for the regen cycle to complete. If this process takes longer than 30 minutes or the check engine light comes on, call the shop immediately for assistance. We'll know the procedure is complete when the DPR filter warning light turns off and the engine returns to idle speed.

Active DPF regenerations need to burn extra fuel to achieve the high exhaust temperature for soot oxidation, which results in the increased fuel consumption rates.
All you have to do is get your car on an A road or motorway on a regular basis, such as every 300 miles. You then need to run it for 10-20 minutes at speeds in excess of 40mph. This will heat up your exhaust and burn off any soot in the filter.
DPF deletion does not affect vehicles' engine performance, power generation and horsepower. It can improve performance by freeing up space in the engine bay and reducing weight. However, there are some potential drawbacks to consider before going ahead with a DPF delete.
So it is advised that drivers regularly give their diesel vehicle a good 30 to 50 minute run at sustained speed on a motorway or A-road to help clear the filter. However, not all drivers do this type of driving regularly – which is why manufacturers have designed an alternative form of regeneration.
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.
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.
How long does the regeneration take? The DPF regeneration cycle takes approximately an hour and a half (1 1/2 hours) to complete and can be completed as part of a routine service.
In a Diesel engine with a Diesel particulate filter (DPF) system, high-sulfur fuel causes white smoke containing odorous and harmful pollutants during DPF regeneration.
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.
Is it illegal to remove a diesel particulate filter? Yes, it is illegal. Owners face fines if caught and removing a DPF can also invalidate your car insurance policy.
Due to the extensive reliability issues that an EGR can cause, people take it upon themselves to make modifications to the EGR. You should know that any of these modifications are illegal, and the fines if you are caught are significant.
The main reason is that, first and foremost, it is highly illegal. Removing any emissions device on a diesel engine or adding a non-SMOG-compliant product carries a punishment of up to a $5,000 fine per unlawful part installed.
Heat the engine
The easiest and cheapest method of DPF filter cleaning is by driving the vehicle for a long-distance at high revs per minute.
While your vehicle won't stop running the moment the light turns on, continuous driving can lead to more severe issues like decreased fuel efficiency, reduced performance, and in the worst case, engine damage. An illuminated DPF light will cause an MOT failure.
How does DPF regeneration occur? The regeneration occurs automatically, usually without the driver being aware that it is taking place. In the majority of cases, the process is carried out when the engine and exhaust system has reached normal operating temperature and the vehicle is travelling at over 40mph.
Once the DPF clean has been performed a regen can occur. Whenever it is necessary to perform a forced regen an engine oil change is required after the regen.
If your car has an automatic transmission, shift your gears in a manual mode by moving the gear shift gently. No need to use the speed limiter, it is with no seeming value added. Ride like this for a minimum of 30 minutes. This will initiate a regeneration cycle, and your DPF will be cleaned.
The parked regen, sometimes called a DPF Regeneration, is a self-cleaning process that occurs when soot builds up inside the Diesel Particulate Filter (DPF). The DPF helps to maintain efficient, environmentally friendly rental trucks while meeting Environmental Protection Agency (EPA) emissions requirements.
