The particle filter indicator light is on and you do not know what caused the problem. The particle filter is mainly found in vehicles Diesel, even though we will now see it in petrol vehicles. Before starting repairs in the Suzuki Sx4, it's wiser to know where this problem comes from. What is a FAP for? Why is the light on? What can be the most regular concerns? In this text, we will make a point by point overview. 
What is a FAP for on your Suzuki Sx4
As its designation presages, it is used to filter out microscopic particles harmful of the engine block. The molecules are so small that they easily enter your body. It is also Peugeot who created this FAP. Your catalyst has the role of reducing the dose of particles produced by the engine, and the particle filter collects the rest. It is therefore essential to have a particle filter in good condition in case you do not want the Suzuki Sx4 to pollute.
Why the FAP indicator light on your Suzuki Sx4
The FAP of your Suzuki Sx4 is clogged
This is the most common concern. Indeed, a particle filter becomes blocked over time. Particles collect and prevent the flow of exhaust gases. A priori, the particulate filter of the Suzuki Sx4 must be cleaned on its own and therefore eliminate this waste. On the other hand, if it is too old it will have to be replaced.
An electronic problem
The concern about the LEDs is that we are in no way certain that there is a concern. Indeed, it often happens that an indicator light goes off while the Suzuki Sx4 runs without problem. Your particle filter has several electronic probes that issue a warning to the indicator. If these probes do not work well while this particle filter is working properly, it is conceivable that the indicator light comes on.
What to do if the FAP indicator on your Suzuki Sx4 lights up?
To begin, it is perfectly forbidden to remove the particulate filter from your Suzuki Sx4! It is considered an offense. You are able to check the sensors to see if they are working properly. If these work well, the problem comes from the FAP. If it was dirty, it can be repaired by rolling in the towers for 10 to 15 minutes. Do not accelerate too much, the process can damage the engine. We advise you to drive to 3000 rpm. The engine temperature will therefore carbonize the stored dirt and purify the particulate filter. If this technique does not work, you will have to replace it with a new one.
Conclusion:
Your damaged fap will pollute and decrease acceleration. It is essential to replace it. Post a comment in case this post helped you. See you soon !
