The light on your particle filter is triggered and you do not know what the malfunction is. The particle filter is mainly found on cars Diesel, even though they are now found on petrol cars. Just before you get into repairs on the Renault Grand Espace 3, it remains necessary to know where this concern comes from. How does a particle filter work? Why does the light come on? What are the most common dysfunctions? In this article, we will go over the subject. 
What is a DPF on your Renault Grand Espace 3 for?
As its designation suggests, its role is to purify microscopic molecules toxiques of your engine. The molecules are so small that they easily enter our body. For your information, it is Peugeot who created this particle filter. The catalyst is used to reduce the level of molecules emitted from the engine, while the particle filter collects the remains. It is therefore necessary to have an operational FAP if you no longer want the Renault Grand Espace 3 to contaminate the air you breathe.
Why the FAP indicator light on your Renault Grand Espace 3
The FAP of your Renault Grand Espace 3 is clogged
Indeed, it is the most frequent dysfunction. No wonder, a particle filter clogs the more time passes. Molecules pile up and thus block the evacuation of exhaust gases. A priori, the particulate filter on the Renault Grand Espace 3 should be automatically cleaned and thus eliminate the clumps. However, if the latter is damaged it is necessary to replace it with a new one.
An electronic problem
The concern for the LEDs is that we are not sure of the malfunction. Undeniably, it sometimes happens that a warning light is lit while the Renault Grand Espace 3 is running perfectly. The particle filter has electronic sensors that send the message to the indicator. When your probes are not working well while the particle filter is doing well, the indicator light may be on.
What to do if the FAP indicator on your Renault Grand Espace 3 lights up?
Above all, it is completely illegal to remove the fap from your vehicle! Indeed, it is considered a crime. You can check the sensors to see if they work well. In case they themselves work perfectly, the concern comes from the Particle filter. If it was filthy, you can clean it by driving on a diet for 10 to 15 minutes. Do not climb too much in the towers, the process could damage the engine. It is advisable to drive to 3000 revolutions minutes. The engine temperature can therefore burn the stored soot, and thus clean this particle filter. If such manipulation really does not work, it will have to be replaced by a new one.
Conclusion:
A damaged particle filter will then pollute as well as reduce the power of the vehicle. It therefore remains necessary to have it changed. Write a comment if this post helped you. See you soon !
