Your particle filter indicator light comes on and you don't know where the problem is coming from. The particle filter is present mainly for cars Diesel, even if we find them today for gasoline automobiles. Before starting repairs for the seat leon, it is necessary to know where this concern comes from. How does a particle filter work? Why is the light on? What are the most common concerns? In this article, we will go over the question. 
What is an FAP on your seat leon for?
As its name suggests, it is used to purify microscopic molecules harmful of the engine block. These kinds of molecules are so small that they easily fit into your body. It is also Peugeot who created this particle filter. The catalyst has the role of reducing the quantity of molecules emitted from the engine block, and the particle filter collects the rest. It remains essential to have a particulate filter in good condition in case you do not want the seat leon to pollute.
Why the FAP indicator lights up on your seat leon
The FAP of your seat leon is clogged
Indeed, this is the most usual concern. No worries, the particulate filter gets dirty the more time passes. The molecules form clusters and then prevent the proper circulation of exhaust gases. Normally, the particle filter in the seat leon should clean itself and therefore remove this soot. However, if it is particularly old, you must replace it with a new one.
An electronic problem
The problem with these indicator lights is that we are not necessarily certain to have a problem. For example, it sometimes appears that an indicator light is on while the seat leon is working properly. This particle filter has a few electronic sensors that transmit the warning to the dashboard. If your probes do not work well while your particle filter works properly, it is likely that the indicator light comes on.
What to do if the FAP indicator on your seat leon lights up?
First, it is completely prohibited to remove the particle filter on your seat leon! It is considered an offense. You can check the sensors to see if they are working properly. Assuming these work perfectly, the concern must come from the FAP. If the latter is filthy, it is possible to repair it by driving on excessive speed for 10 minutes. Do not accelerate too much either, it may damage the vehicle. We advise you to drive at 3000 rpm. The vehicle temperature should burn the stored soot and release the particulate filter. When such a technique does not work at all, you will have to replace it.
