Your light on your FAP turns on and you do not know where the problem comes from. The FAP mainly exists for cars Diesel, although we will find them now for petrol cars. Before attempting repairs for the hyundai i30, it remains essential to know what is causing the malfunction. How does a FAP work? Why does the indicator light come on? What are the most regular concerns? In this text, we will go around the question. 
What is a DPF on your hyundai i30
As its name presages, its role is to purify microscopic particles harmful of your vehicle. These kinds of molecules are so small that they can easily fit into our body. Note that this is Peugeot who invented the FAP. The catalyst's role is to restrict the amount of particles generated from the engine block, while the particle filter collects waste. It is therefore essential to have a FAP in good working order if you no longer want the hyundai i30 to contaminate the air you inhale.
Why the FAP indicator light on your hyundai i30
The FAP of your hyundai i30 is clogged
Indeed, this is the most common concern. No wonder, a particle filter clogs over time. Particles pile up and thus obstruct the circulation of exhaust gases. As a general rule, the particulate filter of the hyundai i30 is supposed to clean up on its own and thus remove this soot. Unfortunately, if the latter is damaged, it will have to be changed.
An electronic problem
The concern with these LEDs is that you are never sure you have a concern. In fact, it sometimes appears that a warning light comes on while the hyundai i30 is operating properly. The particle filter has a few electronic probes that issue the warning to the indicator. If your probes do not work well when this particle filter works properly, it is conceivable that the indicator light comes on.
What to do if the FAP indicator on your hyundai i30 lights up?
Firstly, it is completely forbidden to remove the particle filter on your vehicle! This is punishable by law. You will need to check the sensors to see if they work well. If they work well, the fault comes from the Particle filter. If the latter turns out to be filthy, it is possible to unclog it by driving on over-regime for ten minutes. Do not climb too much into the towers, this may damage the vehicle. It is advisable to climb to 3000 rpm. The heat of the engine block will therefore burn out this encrusted dirt, and therefore clean this particle filter. When this manipulation is still unsuitable, it should be changed.
Conclusion:
The damaged particle filter can pollute and reduce the power of the vehicle. It is therefore essential to take care of it. Post a comment in case this file served you. Good walk !
