What is a FAP used for on your seat altea

As its name presages, its role is to purify microscopic molecules toxiques of the motor. The molecules are so tiny that they easily enter our body. For your information, it is Peugeot who developed the particulate filter. The catalyst's role is to reduce the level of molecules produced by the engine, while the FAP collects the remains. It is therefore essential to have a FAP in good condition if you no longer want the seat altea to contaminate the air you inhale.

Why the FAP light comes on on your seat altea

The FAP of your seat altea is clogged

This is the most recurring problem. No worries, your FAP becomes clogged over time. These molecules collect and thus block the circulation of your exhaust gases. A priori, the seat altea FAP can purge itself automatically and therefore destroy this waste. However, if this one is particularly old you need to replace it.

An electronic problem

The concern with these LEDs is that we are by no means sure that there is a problem. Undeniably, it sometimes happens that an indicator light is lit while the seat altea works perfectly. The FAP has several electronic probes that send a warning in the direction of the indicator. If these probes do not work well while this FAP is going well, it remains possible that the LED is on.

What to do if the FAP indicator on your seat altea lights up?

First, it is absolutely forbidden to remove the particle filter from your seat altea! It is punishable by law. You should check the sensors to see if they work perfectly. In case these work well, the problem comes from the Particulate filter. If it turns out to be dirty, you can unclog it by driving on over-duty for about ten minutes. Do not accelerate too much either, the process can damage the engine. We advise you to go up to 3000 rpm. The heat of the engine block should burn out the encrusted soot, and therefore release your DPF. If such a scheme does not work at all, it must be replaced by a new one.

Conclusion:

The fap in bad condition should pollute and cause loss of power. It is therefore essential to have it changed. Leave us a comment in case this ticket served you. See you soon !
