Your FAP warning light goes off and you do not know what caused the problem. FAP is mainly found in cars Diesel, even if they can be found today in gasoline automobiles. Before attempting repairs in your Citroen Nemo, it is wiser to know what is causing the malfunction. What is the role of a FAP? Why does the witness go off? What are the most common concerns? During this file, we will make a point by point topo. 
What is a FAP for on your Citroen Nemo
As its name suggests, it is used to purify microscopic molecules toxiques of the vehicle. These kinds of molecules are so tiny that they easily enter our body. For information, it's Peugeot who developed the FAP. The catalyst's role is to lower the dose of molecules produced by the vehicle, and the FAP collects the rest. It therefore seems essential to have a particulate filter in good condition in case you no longer want your Citroen Nemo to contaminate the air you inhale.
Why the FAP indicator light on your Citroen Nemo
The FAP of your Citroen Nemo is clogged
This is the most common concern. Indeed, a FAP clogs up as time goes by. These molecules collect and thus prevent the proper circulation of these exhaust gases. Ordinarily, the FAP on your Citroen Nemo is supposed to be purged automatically and therefore eliminate this waste. However, if it is too old you must change it.
An electronic problem
The concern with these indicator lights is that we are by no means certain to have a concern. Undeniably, it often happens that an indicator light comes on while your Citroen Nemo turns without worries. This FAP has several electronic probes which transmit the message to the indicator. If your sensors are not working well while your FAP is working perfectly, it is plausible that your witness will go off.
What to do if the FAP indicator light on your Citroen Nemo lights up?
First of all, it is perfectly forbidden to remove the fap on your vehicle! It is an offense. You can check the sounders to see if they are working well. If they themselves work well, the dysfunction comes from the FAP. If the latter is dirty, it can be cleaned by rolling in the towers for 10 minutes. Do not accelerate too much either, it can damage the car. We advise you to drive at 3000 revolutions minutes. The heat of the vehicle should therefore burn out the stored soot and purify the FAP. When such a method is not suitable, it will have to be changed.
Conclusion:
A damaged particle filter will then pollute but also cause loss of power. It is therefore essential to take care of it. Post a comment if our article helped you. Good road !
