The indicator light on your DPF turns on and you don't know where the problem is coming from. FAP is mainly found on cars Diesel, even if they are now found on gasoline cars. Before you get into repairs on your Renault Dezir, it remains important to know where this problem came from. How does a particle filter work? Why is the indicator light on? What are the most common concerns? In this article, we will give a point by point overview. 
What is a FAP used for on your Renault Dezir
As its name suggests, its role is to filter out microscopic molecules harmful of your car. The molecules are so small that they can easily enter your body. For your information, it is Peugeot who made this particle filter. The catalyst is used to lower the level of molecules generated by the engine block, and the particle filter collects the rest. It therefore remains essential to have a particulate filter in good working condition if you do not want your Renault Dezir to pollute.
Why the FAP indicator light on your Renault Dezir
The FAP of your Renault Dezir is clogged
This is the most common concern. No worries, the particle filter becomes clogged as time goes by. Molecules form clusters and then hinder the flow of these exhaust gases. A priori, the particle filter on your Renault Dezir will be able to be automatically cleaned and remove this soot. However, if this one is particularly old you are going to have to replace it with a new one.
An electronic problem
The problem with these indicator lights is that we are in no way sure that there is a problem. Indeed, it sometimes happens that an indicator light comes on while your Renault Dezir is running without worries. The particle filter has a few electronic probes which issue a warning to your dashboard. When these sensors malfunction while the particle filter works properly, it is possible that the indicator light will come on.
What to do if the FAP indicator on your Renault Dezir comes on?
First, it is absolutely forbidden to remove the particulate filter from your vehicle! It is considered an offense. You should examine the sensors to see if they are working properly. Assumed that they work correctly, the problem comes from the FAP. If it turns out to be dirty, you can clean it by going on a diet for ten minutes. Without exaggerating, it could damage the car. It is advisable to climb to 3000 rpm. The heat of the engine block will carbonize the stored soot, and therefore clean this particle filter. In the event that this procedure really does not work, it is necessary to replace it with a new one.
Conclusion:
Your damaged particle filter will then pollute but also decrease the power of the vehicle. It remains essential to change it. Post a comment if our file served you. Good road !
