How much does a forced regen cost?

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. How can I do a forced regeneration?

How long does a forced regen take?

On average, it takes between thirty and sixty minutes to complete a forced regeneration. The substantial heat required for the regen renders the engine and aftertreatment system untouchable until it has time to cool down.

Can a forced regen damage engine?

Force regeneration of the particulate filter

The ash from the engine oil accumulates on the inner walls of the ceramic and in the pores. This increases the pressures in the DPF and if clogged, can even damage the engine.

How often should you do a forced 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.

When should I do a forced 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 a DPF last?

Do you need to change oil after forced regen?

Whenever it is necessary to perform a forced regen an engine oil change is required after the regen. Why, remember before how extra fuel is injected to get the DPF hot enough to regen, this extra fuel will dilute the engine oil.

What happens if your diesel doesn't regen?

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.

Can a truck regen while driving?

The most common form is passive regeneration. This occurs while the truck is in motion when the heat of the exhaust burns the soot off the DPF. On the other hand, active regeneration occurs when the exhaust isn't quite hot enough to remove the accumulated soot.

How do you tell if your DPF is clogged?

Why is my truck asking for a regen so often?

Regen problems generally arise where city driving, excessive idling or light duty cycles are encountered. Or, if other engine components such as EGR valves, turbochargers, injectors are fouled or not working properly. DPF regeneration cycles then become more frequent, and more prolonged!

Can a diesel ReGen while driving?

Most engine management systems will actively regenerate the DPF when the car is driven at speeds above 40mph for around 10 to 15 minutes. The soot particles trapped in the filter will soon burn away and the warning light should switch off.

Which cars have the most DPF problems?

Can you operate a tractor during ReGen?

Other ReGen tips

If you should happen to get a ReGen notification when you are minutes away from finishing your tractor chores for the day, we recommend you leave your tractor running while the ReGen process completes.

Does regen use more fuel?

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.

How much does it cost to clean a diesel particulate filter?

DPF cleaning cost can be significantly lower than the cost of a replacement, and cleaning can restore the filter's efficiency and performance. The cost of DPF cleaning is around $200 to $500 for most models.

Can you unblock a DPF yourself?

DPF regeneration – a DPF regeneration is the straightforward process of driving your vehicle at higher-than-normal revolutions per minute (RPM) for at least 30 minutes. In doing so, you're given your vehicle a chance to sustain optimum operating temperatures which help to burn any blockages.

What happens if I keep driving with blocked DPF?

Blocked DPFs wreak havoc with the delicate balance of your engine by preventing the normal venting of gases, which causes a variety of engine issues, as described above. In addition to reduced power and fuel efficiency, a blocked filter may eventually cause a dangerous mechanical malfunction and break your engine.

Can a fully blocked DPF be cleaned?

Some garages can clean blocked DPFs, in a process called forced regeneration. This usually costs around £100 and, while it's not a 100% guaranteed fix, it's usually successful in removing the excess soot and allowing the DPF to work and automatically regenerate again.

Does the check engine light come on during regen?

This is your second warning, and it's more urgent. It's telling you a parked regeneration is necessary, and you need to perform it as soon as possible. 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.

How long should a parked regen take?

How long does a parked DPF regen take? It takes approximately 20-60+ minutes. It will continue to regen until the soot level has reached 'low' or '0%. ' Some trucks will let you monitor your soot level gauge on the dashboard.

What happens if regen takes too long?

If your forced DPF regen lasts closer to an hour or continues beyond that, it likely suggests that your exhaust temperatures are not building up high enough to successfully burn off the soot collected in the DPF and that the truck is still trying to bring down those soot levels.

Do diesels smoke during regen?

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.

What mileage is too high for a diesel car?

To be clear - avoid diesel cars with over 100,000 miles on the clock.
