The dysfunctions of particulate filters are relatively regular. When the malfunction occurs, we can detect symptoms relatively disparate, like a loss of power. It is rather exceptional that this malfunction of the Citroen Sm comes from the FAP itself, but it is undoubtedly impacted. We will thus try to understand the principle of a fap, then to grasp the nature of this dysfunction.problem-fap-Citroen-Sm

What is the FAP of your Citroen Sm for?

The fap serves to preserve you. As its designation suggests, its role is to filter particles harmful for health. Originally, there was a particulate filter in particular in diesel mechanics, but they will be all the more frequent in petrol mechanics. The particles in question produced by the Citroen Sm are so tiny that they are able to quickly penetrate the lungs. Researchers have shown that these particles can cause serious illness. For this reason, your FAP has an essential role. When a malfunction occurs, it is therefore important to pay attention to it. The catalyst will reduce the particles produced, then your particle filter will collect these particles which have managed to pass.

FAP of your blocked Citroen Sm: origins and solutions

Let's get into the thick of it. You can find out where your malfunction comes from and what to do to fix it.

Particulate Filter: The problem comes from poor combustion.

If you mostly drive in urban areas, the particle filter of this Citroen Sm will clog faster. We advise you to take a quarter-hour tour at 3000 rpm in order to unclog it.

Conclusion

The Citroen Sm Particulate Filter is one of the last components of the mechanical . By the time he himself has a malfunction, there is a good chance that the cause of the malfunction is before.
