The particle filter indicator light turns on and you do not know what the problem is. The particle filter is mainly found on cars Diesel, even though they can be found today on petrol cars. Before you get into repairs on this Citroen Survolt, it remains essential to know what is the source of this problem. How does a FAP work? Why is the light on? What are the most common problems? In this article, we will go over the question. 
What is a FAP for on your Citroen Survolt
As its name presages, the latter has the role of purifying microscopic particles harmful of the engine block. These particles are so tiny that they can easily enter our body. Note that this is Peugeot who developed this FAP. Your catalyst has the role of reducing the dose of particles generated by the engine block, while the FAP collects the surplus. It is therefore essential to have an operational particle filter if you no longer want this Citroen Survolt to contaminate the air you inhale.
Why the FAP indicator light on your Citroen Survolt
The FAP of your Citroen Survolt is clogged
This remains the most recurrent problem. No worries, the FAP clogs up over time. These particles pile up and then hinder the evacuation of exhaust gases. A priori, the FAP in this Citroen Survolt is supposed to purge itself and therefore expel this soot. On the other hand, if this one is particularly old you will have to replace it.
An electronic problem
The problem with the indicator lights is that you are in no way sure that there is a problem. Indeed, it happens when a warning light comes on while this Citroen Survolt works perfectly. The FAP has several electronic sensors which send a warning to your warning light. In the event that your sounders have a problem while this FAP is working properly, it is still possible that your LED will go off.
What to do if the FAP indicator on your Citroen Survolt lights up?
At first, it is completely prohibited to remove the fap on your Citroen Survolt! This is considered an offense. You will need to check the probes to see if they are working properly. If these work perfectly, the problem stems from the FAP. If it turns out to be dirty, it can be cleaned by rolling the towers for 10 to 15 minutes. Do not accelerate too much either, it may damage the engine. We advise you to go up to 3000 rpm. The temperature of the engine block will carbonize the stored soot, and therefore clean the FAP. If this manipulation still does not work, it will have to be changed.
Conclusion:
A bad particle filter will pollute and make you lose power. It therefore remains essential to replace it. Leave a comment in case our post helped you. Good walk !
