What is a FAP used for on your Kia Pro Cee D 2
As its name presages, its role is to filter microscopic particles harmful of your car. These molecules are so tiny that they can easily enter your body.

Why the FAP indicator lights on your Kia Pro Cee D 2
The FAP of your Kia Pro Cee D 2 is clogged

An electronic problem
The concern for sighted people is that you are not sure if you have a concern. In practice, this appears sometimes when an indicator light shines while this Kia Pro Cee D 2 works without problem. Your FAP has several electronic sounders which send a warning to the dashboard. When your sounders malfunction while your FAP is fine, it is conceivable that your LED will go off.
What to do if the FAP indicator on your Kia Pro Cee D 2 lights up?
First, it is completely illegal to remove the particle filter on your vehicle! Indeed, it is punishable by law. You have the option of examining the sensors to verify that they are functioning properly. If they themselves work perfectly, the malfunction comes from the FAP. If the latter is dirty, you can repair it by driving in the towers for 10 to 15 minutes. Without exaggerating, this could damage the engine. We advise you to go up to 3000 rpm. The heat of the engine block can thus burn the stored dirt, and consequently release the FAP. When this manipulation is not suitable, it must be changed.
