When to change DPF?

On average, the diesel particulate filter needs to be replaced every 150 kilometers. However, this frequency depends on whether DPF is added or not, and also depending on the car model and its engine. Therefore, it should be checked in the maintenance log.

🗓️ Every how many kilometers do you need to change DPF?

Le particulate filter (DPF) plays a role in reducing particulate emissions from your vehicle. It sits on the exhaust line, where it traps particles in its filter before they leave the vehicle.

Since 2011 in France, FAP is compulsory for all vehicles with diesel engine new. But it is even found on some gasoline cars. It is one of the pollution control systems that have been developed and widely adopted in recent years.

After particle filtration, DPF also has cycle regenerationthat should burn them. Indeed, these particles accumulate as soot and thus risk clogging the FAP. To prevent this, he will raise the temperature so that above 550 ° C, wash.

However, this implies regular driving with sufficient engine speed. The DPF of cars that mainly make urban or short trips clog up much faster and thus the engine can be damaged or even damaged.

Even a well-maintained and cleaned diesel particulate filter usually does not extend the life of the vehicle. Replacing the DPF depends on the type of filter in question. Indeed, the particulate filter can additive or not, that is, should a special DPF additive be used.

. FAP without additives can extend the life of your vehicle if it is regenerated periodically. The DPF should only be replaced in the event of a malfunction or malfunction, if cleaning is not sufficient to restore normal operation.

Un FAP additivity needs to be changed every 80 to 200 kilometers, depending on your car model. The most recent particulate filters have a longer service life: usually 150 000 km average. But it also depends on the manufacturer and the engine.

Therefore, in order to know when to change DPF, it is important to consult with your service book or an Automotive Technical Review (RTA), which will tell you the intervals specific to your vehicle.

Of course, it is also necessary to replace the DPF if it is too clogged or damaged. Pay attention to the symptoms that tell you about DPF clogging in order to react as quickly as possible: in this case, cleaning will be enough to return it to its original state.

👨‍🔧 How do you know when you need to replace the particulate filter?

A clogged particulate filter has different symptoms:

• Loss of engine power : The engine can no longer run normally and lacks power. It chokes when starting off and accelerating, or even stalls.
• DPF indicator ou engine warning light ignited : A message about the risk of DPF clogging may also appear depending on the vehicle.
• Excessive fuel consumption : to compensate for the decrease in engine power, it will be used more and therefore consume more.

If you don't react very quickly, your engine could be damaged. degraded regime for self-defense. Then it will only work at idle and low speed.

If you respond quickly, a DPF replacement may not be necessary. Cleaning the garage can solve the problem. However, the appearance of these symptoms is a bad sign: it means that the FAP is already blocked. Therefore, do not continue driving, so as not to damage it.

⏱️ How to extend the life of your particulate filter?

If you have DPF installed, you will need to replace it every 150-200 km O. However, whichever type of particulate filter you use, its service life can be extended.

For this, it is important that it regenerates regularly. On average, once a month, drive onto the highway and drive through 15 to 20 minutes over 3000 rounds / min... This will clean the DPF and prevent clogging.

If the filter is clogged, react immediately: by having it cleaned by a professional, you can probably get it repaired and avoid having to replace it. Don't wait, you will damage the DPF and replacement will be inevitable.

Now you know when to change the particulate filter! As you may have figured out, you should inquire about your filter type and your manufacturer's recommendations because DPF life varies from one vehicle to the next. Also look out for symptoms indicating that the DPF is blocked for a quick response.
