Your FAP light turns on and you do not know what the malfunction is. FAP is found more in vehicles Diesel, even if we find them more and more in petrol vehicles. Before launching into repairs in the Volkswagen 411, it is essential to understand where this problem comes from. What is the role of a FAP? Why does the light come on? What are the most regular concerns? During this file, we will go around the question. indicator-fap-Volkswagen-411

What is a FAP used for on your Volkswagen 411

As its designation presages, the latter has the role of filtering microscopic particles harmful of the vehicle. The molecules are so small that they easily fit through your body. Note that this is Peugeot who invented this FAP. The catalyst has the role of reducing the quantity of particles produced from the engine block, and the particle filter collects the waste. It is therefore necessary to have an operational FAP in case you do not want the Volkswagen 411 to pollute the environment.

Why the FAP indicator light on your Volkswagen 411

The FAP of your Volkswagen 411 is clogged

This remains the most usual dysfunction. And that's normal, the particle filter becomes clogged over time. Particles pile up and thus impede the proper circulation of exhaust gases. A priori, the particulate filter in the Volkswagen 411 must purge on its own and eliminate this waste. However, if the latter is old it will need to be replaced.

An electronic problem

The concern about the indicator lights is that we are not necessarily certain to have a malfunction. In practice, this sometimes happens that a warning light is lit while the Volkswagen 411 is operating properly. Your particle filter has a few electronic probes that send a warning to the indicator. If the sounders do not work well while this particle filter is working perfectly, it is likely that the indicator will go off.

What to do if the FAP indicator light on your Volkswagen 411 lights up?

To start, it is completely illegal to remove the fap on your vehicle! Indeed, it is a crime. You will be able to check the probes to see if they are working properly. In case these work well, the problem comes from the Particulate filter. If it was dirty, you can clean it by driving on a diet for 10 to 15 minutes. Also do not accelerate too much, the process could damage the car. We advise you to drive to 3000 revolutions minutes. The engine temperature should therefore burn the stored soot, and therefore clean the particulate filter. If this method does not work at all, you should replace it.

Conclusion:

Your damaged particle filter should pollute and make you lose power. It therefore remains important to replace it. Leave a comment if our post was useful to you. See you soon !
