Your FAP light goes off and you don't know where the problem is coming from. FAP is present especially for cars Diesel, even if we now find them for gasoline cars. Just before you get into repairs for your Renault Espace 3, it is wiser to understand where the concern comes from. How does a FAP work? Why does the light come on? What can be the most frequent concerns? In this article, we will cover the subject. 
What is a DPF on your Renault Espace 3 for?
As its designation suggests, it is used to filter microscopic particles toxiques of the car. The molecules are so small that they easily enter our body. For information, it's Peugeot who made the FAP. The role of the catalyst is to reduce the quantity of particles produced by the engine block, while the FAP collects the waste. It is therefore essential to have a particle filter in good working condition if you no longer want your Renault Espace 3 to contaminate the air you inhale.
Why the FAP indicator light on your Renault Espace 3
The FAP of your Renault Espace 3 is clogged
This remains the most frequent problem. No wonder, your FAP clogs the more time passes. These particles collect and then prevent the circulation of these exhaust gases. Normally, the DPF on your Renault Espace 3 can be cleaned automatically and thus flush out clumps. On the other hand, if this one is particularly old it will have to be replaced.
An electronic problem
The problem with the LEDs is that you are in no way sure of the problem. Indeed, it happens sometimes that a light flickers while your Renault Espace 3 is working perfectly. This FAP has several electronic probes which issue a warning to the indicator. When these probes malfunction while the FAP works perfectly, it is conceivable that your indicator light will go off.
What to do if the FAP indicator on your Renault Espace 3 lights up?
To begin, it remains completely forbidden to remove the fap on your Renault Espace 3! It is punishable by law. You should check the sensors to see if they are working properly. Assuming these are working properly, the concern must come from the FAP. If it is filthy, you can clean it by driving in towers for 10 to 15 minutes. Do not accelerate too much either, the process could damage the car. We advise you to drive to 3000 rpm. The engine block temperature should actually burn the stored soot, and release the DPF. In the event that this manipulation is not suitable, you will need to have it changed.
