How to Burn DPF by Yourself: While Driving or Stationary?

DPF is a crucial component of the exhaust system in diesel cars. It is responsible for cleaning exhaust gases of particulate matter that is harmful to both the environment and human health. Due to continuous use and operating in difficult conditions, the filter gradually loses its original properties, leading to the accumulation of soot and ash. To remove the excess buildup, a process known as DPF regeneration is used, which can be performed either while driving or stationary. In the following part of the post, I will briefly discuss both methods, allowing each driver to decide which option is best suited for their vehicle.

Is DPF regeneration necessary?

Over the years, it has become evident that the diesel particulate filter has become a source of trouble for many diesel vehicle owners. Why? Because it can get clogged rather quickly. If left untreated, this situation can have a detrimental effect on engine performance—ignoring a clogged DPF can negatively impact the efficiency of the engine (for instance, causing acceleration issues).

To avoid such issues (or even worse ones), it's important to remember about DPF regeneration, which involves removing excess contaminants to restore the filter to its original properties.

How to Regenerate DPF Yourself – Two Methods

More knowledgeable drivers often wonder how to regenerate the DPF themselves – it's worth knowing that it's not complicated, but it does require meeting certain conditions. Currently, this process can be done in two ways: while driving or stationary (alternatively, you can visit a service center and have professionals handle it). How does it work in practice, and which method is better?

Regenerating the Diesel Particulate Filter While Driving

This method takes advantage of the natural process of burning off particulate matter. Why? Because diesel-engine vehicles are capable of automatically initiating the DPF regeneration process. This is possible when the engine is provided with the right conditions (revolutions per minute and engine load). In such a situation, the computer sends a signal to the injectors to supply an additional dose of fuel, which is burned directly in the filter, allowing effective removal of the contaminants.

This method is recommended for drivers who regularly cover long distances, such as on highways.

Regenerating DPF While Stationary

The second method of regenerating DPF yourself involves connecting a diagnostic tester to the car. Using this tool, you can force the regeneration process (after connecting, the computer recognizes that the diesel particulate filter is contaminated). During regeneration, the engine runs at high revolutions, which helps to reach the required temperature to burn off the contaminants. It is important to note that when considering this method, you should ensure good ventilation, so avoid doing it in enclosed spaces or around other people. Regeneration while stationary is especially suitable for people who frequently drive in traffic jams (in such conditions, the car cannot automatically initiate the DPF regeneration process, leading to a quick buildup of filter clogging).

How to Regenerate the DPF Yourself? Which Method to Choose?

It all depends on your driving style. If you regularly drive on fast roads (highways, expressways), you don’t need to force regeneration while stationary – your car will automatically signal when the filter needs to be cleaned (usually with an indicator on the dashboard). However, if you mostly drive in the city and regularly cover short distances, consider regenerating the filter while stationary – just remember that this process puts significant strain on the engine.

Regeneration Isn't Everything – Cleaning DPF with Chemical Agents

Now that you know how to regenerate the DPF yourself, here’s a little tip: you can maintain the cleanliness of the filter in other ways as well. While regeneration (especially automatic) is essential, you should know that there are other methods to clean the DPF. The best example of this is using special cleaning products. At this point, I encourage you to try TEC 2000 Diesel System Cleaner, which has been used for years to clean diesel particulate filters of soot and other contaminants. It’s a product that contains several solvents and powerful cleaning agents, which not only dissolve stubborn dirt but also prevent it from re-depositing on the DPF walls and beyond.

Regular use of DSC (twice a year):

• Helps reduce black smoke,
• Thoroughly cleans the DPF, injectors, and fuel system,
• Significantly reduces harmful exhaust emissions, while improving engine performance at idle.

I encourage you to try it today.
