What is a FAP used for on your Lancia Appia

As its designation indicates, it is used to filter microscopic molecules toxiques of the motor. The molecules are so small that they easily enter your body. It is also Peugeot who developed this particle filter. The catalyst's role is to decrease the quantity of molecules produced by the engine, then the FAP picks up the rest. It is therefore necessary to have a particulate filter in good condition in case you do not want your Lancia Appia to pollute.

Why the FAP indicator light on your Lancia Appia

The FAP on your Lancia Appia is clogged

Indeed, this is the most frequent concern. And this is normal, the FAP becomes blocked over time. Molecules pile up and block the evacuation of these exhaust gases. In general, the FAP on your Lancia Appia can purge itself and therefore destroy this soot. However, if this one is particularly old it must be replaced.

An electronic problem

The problem with LEDs is that you are never sure you have a problem. Indeed, it frequently appears that an indicator light flickers while your Lancia Appia is running without problems. This FAP has electronic sounders which transmit a message to the dashboard. If these probes ever have a problem while the FAP is working properly, it is plausible that your indicator light is on.

What to do if the FAP light on your Lancia Appia lights up?

At first, it is completely forbidden to remove the particle filter on your Lancia Appia! It is punishable by law. You will need to examine the sounders to see if they are working properly. If these work perfectly, the malfunction comes from the FAP. If it was filthy, you can unclog it by driving in towers for 10 minutes. Do not climb too much in the towers, the process could damage the car. We advise you to drive at 3000 rpm. The heat of the vehicle will thus roast the stored soot, and release your FAP. If this technique does not work well, it should be changed.
