The light on your particle filter is on and you do not know where the problem is coming from. The particle filter is present particularly on cars Diesel, even though they can be found today on gasoline automobiles. Before starting repairs on this Opel Mokka, it's wiser to know what the problem is coming from. What is a FAP for? Why does the indicator light come on? What are the most common dysfunctions? During this file, we will go around the subject. 
What is a FAP for on your Opel Mokka
As its designation presages, its role is to filter microscopic molecules harmful of your vehicle. These molecules are so small that they easily enter your body. For information, it's Peugeot who made the FAP. Your catalyst has the role of reducing the level of molecules generated from the engine block, while the particle filter collects the remains. It therefore remains essential to have an operational particle filter if you do not want this Opel Mokka to contaminate the air you breathe.
Why the FAP indicator lights on your Opel Mokka
Your Opel Mokka's FAP is clogged
Indeed, this is the most common problem. No wonder, your particle filter becomes clogged the more time passes. These molecules pile up and hinder the evacuation of your exhaust gases. A priori, the particulate filter on this Opel Mokka is supposed to clean itself and therefore eliminate this waste. That said, if it is particularly damaged it must be replaced.
An electronic problem
The problem with these LEDs is that you are by no means certain that there is a problem. In practice, it sometimes appears that a warning light comes on while this Opel Mokka is working perfectly. The particulate filter has several electronic sensors which send a signal to the indicator. If ever the sensors malfunction when your particle filter is fine, it is possible that your indicator light is on.
What to do if the FAP indicator on your Opel Mokka lights up?
Above all, it is completely illegal to remove the particulate filter from your vehicle! Indeed, it is punishable by law. You are able to check the sensors to see if they are working properly. In case these work well, the concern comes from the FAP. If it was dirty, you will be able to clean it by rolling in the towers for 10 to 15 minutes. Without exaggerating, it could damage the engine. It is advisable to drive to 3000 r / min. The temperature of the engine block should in this way burn out the encrusted soot and purify this particulate filter. When such a technique really does not work, it is necessary to change it.
Conclusion:
Your damaged particle filter will pollute but also reduce the power of the vehicle. It is therefore essential to replace it. Leave us a comment if this post was useful. Good walk !
