Your FAP warning light goes off and you don't know where the problem is coming from. FAP exists particularly in vehicles Diesel, even though they are found today in petrol vehicles. Just before starting repairs in the Seat Altea Freetrack, it is wiser to understand what is causing this problem. What is a particle filter used for? Why does the light go on? What are the most common concerns? In this text, we will go around the question. 
What is a FAP used for on your Seat Altea Freetrack
As its designation presages, it is used to purify microscopic particles toxiques of your car. These particles are so tiny that they can easily enter our body. It is also Peugeot who made this particle filter. Your catalyst is used to reduce the amount of particles generated by the engine block, while the particle filter collects the surplus. It therefore remains fundamental to have a FAP in good working condition if you do not want the Seat Altea Freetrack to pollute the environment.
Why the FAP indicator light on your Seat Altea Freetrack
The FAP of your Seat Altea Freetrack is clogged
Indeed, this is the most common concern. Indeed, the particle filter becomes blocked as time passes. The particles form clusters then hinder the evacuation of your exhaust gases. Ordinarily, the particulate filter in the Seat Altea Freetrack must clean itself and expel this waste. That said, if it is particularly old it is essential to replace it.
An electronic problem
The problem with these indicator lights is that you are not sure of the concern. In fact, it often appears that a warning light comes on while the Seat Altea Freetrack works without problems. This particle filter has several electronic sounders which transmit a message to the indicator. If these probes do not work well while the particle filter is working properly, it is plausible that the indicator light comes on.
What to do if the FAP indicator on your Seat Altea Freetrack lights up?
First, it is absolutely forbidden to remove the particle filter from your Seat Altea Freetrack! This is considered an offense. You will have to check the probes to see if they work properly. If they themselves are doing well, the problem comes from the FAP. If it is dirty, you can clean it by rolling the towers for 10 to 15 minutes. Do not climb too much into the towers, this could damage the car. We advise you to go up to 3000 rpm. The temperature of the engine block can actually carbonize these stored dirt, and thus purify your particulate filter. If this manipulation does not work well, you will have to replace it with a new one.
Conclusion:
A particle filter in poor condition can pollute but also cause loss of power. It is therefore important to take care of it. Leave us a comment in case our post was useful. Good walk !
