The indicator light on your FAP is triggered and you do not know where the problem comes from. FAP is particularly present in cars Diesel, although they can be found more and more in gasoline automobiles. Just before starting repairs in Smart For-us, it is important to understand where the malfunction comes from. How does a particle filter work? Why does the light go on? What are the most common problems? In this article, we will give a point by point overview. 
What is a FAP on your Smart For-us for?
As its name suggests, its role is to purify microscopic particles toxiques of your engine block. These molecules are so small that they easily enter our body. Note that this is Peugeot who invented the particulate filter. The catalyst is used to reduce the amount of particles emitted by the vehicle, while the particle filter collects the rest. It is therefore essential to have a particle filter in good condition in case you no longer want the Smart For-us to pollute the environment.
Why the FAP indicator lights up on your Smart For-us
The FAP of your Smart For-us is clogged
Indeed, this is the most usual concern. No wonder, a particle filter becomes clogged as time goes by. Particles collect and thus block the evacuation of your exhaust gases. A priori, the particle filter of the Smart For-us can purge itself and therefore destroy the clumps. However, if the latter is damaged, it will have to be replaced.
An electronic problem
The problem with these indicator lights is that you are in no way sure that there is a problem. Indeed, it sometimes appears that an indicator light is triggered while the Smart For-us works without problems. This particle filter has several electronic probes which emit the signal to the indicator. When these sensors have a problem while the particle filter is working properly, it remains possible that your telltale will start.
What to do if the FAP indicator on your Smart For-us lights up?
First, it is completely illegal to remove the particulate filter from your vehicle! It is considered an offense. You are going to have to check the sounders to see if they are working properly. If these work properly, the malfunction comes from the FAP. If it is dirty, you can clean it by rolling in the towers for 10 minutes. Do not climb too much in the towers, the process can damage the car. We advise you to drive to 3000 rpm. The temperature of the vehicle should in fact carbonize these stored dirt, and thus clean this particle filter. In case this technique does not work well, you will have to replace it with a new one.
Conclusion:
The damaged particle filter should pollute as well as reduce the power of the vehicle. It is therefore important to replace it. Post a comment in case our article was useful to you. See you soon !
