Particle Filter Regeneration: Everything You Need To Know

As an owner of a modern diesel vehicle, it's important to know how to regenerate your particulate filter. Particle filters are an important part of the exhaust system and are designed to remove harmful particles from the exhaust to improve air quality.

Unfortunately, these filters can become clogged with soot and other contaminants, causing reduced performance and a warning light on the dashboard. Fortunately, particle filter regeneration can usually be done yourself or by calling a professional. Note that this procedure varies by make and model, so it's usually important to have a solid basic knowledge of how the car and its exhaust system works.

DPF regeneration

A Diesel Particulate Filter is also known as a DPF (Diesel Particulate Filter). The DPF must be regenerated to prevent the filter from becoming clogged and preventing proper vehicle operation. Once the particulate filter warning light comes on, you need to take action as soon as possible. This could be regenerating the particulate filter yourself, having it done, or even replacing the entire particulate filter. It depends on the problem, so it is important to properly diagnose the particle filtration system before starting the regeneration procedure.

Particle filter light comes on

If the particulate filter warning light comes on, it usually means the particulate filter is clogged and needs to be regenerated. After you've checked for yourself whether this is indeed the case, you can start solving the problem yourself. It's important to know that ignoring warning lights can cause serious problems with your exhaust system and vehicle, especially the engine. Therefore, it is important to act quickly when you see the light come on.

Start particulate filter regeneration

There are several ways to initiate particulate filter regeneration, depending on the vehicle type and particulate filter type. Many modern vehicles regenerate automatically at highway speeds, but some vehicles can initiate regeneration manually using a button on the dashboard or using a special software program or OBD2 device. Here are some general steps you can follow:

  • Warm up the vehicle: The soot filter must be preheated to regenerate effectively, so it is important to warm up the vehicle before starting regeneration.
  • Activating regeneration: Regeneration of the particulate filter is usually activated by the vehicle, but as shown, you can sometimes do this via a button or menu option in the vehicle. If this is not the case, you can use an OBD2 device or special software.
  • Driving at high speeds: During regeneration, you typically need to drive your vehicle at higher speeds so that the combustion process in the exhaust heats up further and burns the soot.
  • Check Status: Monitors the status of the particle filter during regeneration. Some vehicles are equipped with sensors that display status and issue a warning when regeneration is complete.

Particle filter regeneration using OBD2

As mentioned before, it is also possible to regenerate the particle filter using an OBD2 device. OBD2 devices are specific scan tools designed to communicate with a vehicle's on-board diagnostic system. This means you can use the software on your OBD2 device to regenerate the particulate filter. Additionally, OBD2 devices allow you to diagnose and resolve other error codes in your vehicle to keep your vehicle in top condition. Please note that not all OBD2 devices can regenerate particulate filters.

How long does it take to regenerate a particulate filter?

Regeneration of a particle filter typically takes 30 to 60 minutes. Keep in mind that the time it takes for a particulate filter to regenerate depends on the type of vehicle and the degree of blockage. Some vehicles regenerate in just a few minutes, while others take more time. It's also important to note that when regenerating a particulate filter, typically your vehicle must be driven at high speeds to complete the regeneration.

Particulate filter regeneration for vehicle

In the automotive market, there are also cars equipped with modern particulate filters that automatically regenerate when the vehicle is traveling at high speeds. However, if you are having trouble regenerating your particulate filter, you may choose to use one of our devices for help. They can help you regenerate your particulate filter properly and resolve any error codes that may interfere with regeneration.

In conclusion

In this article we explain to you how to regenerate a particle filter. Whether you use an OBD2 device or manually regenerate your particulate filter, it's important to know how to keep your particulate filter in good condition. If you have questions about particulate filter regeneration, please contact your dealer or repair shop for more information. Of course, you can always contact us for equipment recommendations.
