The particle filter light goes on and you don't know what the problem is. The particle filter is mainly found on cars Diesel, even if they are now found on gasoline cars. Just before you start repairs on your Smart Crossblade, it is essential to know where this problem comes from. What is a FAP for? Why does the indicator light come on? What are the most common problems? In this text, we will go around the subject. 
What is an FAP on your Smart Crossblade
As its name presages, the latter is used to purify microscopic molecules harmful of the car. These kinds of molecules are so small that they easily enter your body. Note that this is Peugeot who invented this FAP. Your catalyst's role is to lower the dose of molecules generated by the engine, while the FAP collects the surplus. It is therefore essential to have a particle filter in good condition if you do not want your Smart Crossblade to pollute.
Why the FAP indicator lights up on your Smart Crossblade
The FAP of your Smart Crossblade is clogged
This is the most common problem. And that's normal, your FAP clogs the more time passes. Molecules form clusters and block the flow of exhaust gases. Normally, the FAP in your Smart Crossblade can purge itself and thus eliminate this waste. On the other hand, if it is too old it will have to be replaced.
An electronic problem
The concern with the indicator lights is that we are by no means certain that there is a problem. For example, it sometimes happens that a warning light goes off while your Smart Crossblade is working perfectly. The FAP has a few electronic sensors that send the message to the dashboard. When the sensors do not work well while this FAP is going well, it is plausible that the indicator light comes on.
What to do if the FAP LED on your Smart Crossblade lights up?
First, it is absolutely forbidden to remove the fap from your vehicle! This is punishable by law. You can check the sensors to see if they work perfectly. If they themselves work well, the problem comes from the FAP. If it turns out to be dirty, it can be cleaned by rolling in the towers for ten minutes. Without abusing it, it can damage the engine. We advise you to drive to 3000 rpm. The engine temperature can therefore burn the stored soot, and therefore clean the DPF. If such a technique does not work at all, it will have to be changed.
Conclusion:
The damaged fap can pollute and cause loss of power. It is therefore important to have it changed. Post a comment if our post was useful. Enjoy the road!
