Your particle filter indicator light is on and you do not know what is causing the problem. The particle filter is mainly found for vehicles Diesel, even if we find them today for gasoline vehicles. Before you start repairs for the Volkswagen 1200, it is essential to understand where the malfunction came from. How does a FAP work? Why does the witness go off? What are the most common problems? During this file, we will make a point by point topo. 
What is a FAP used for on your Volkswagen 1200
As its name suggests, the latter has the role of filtering microscopic particles harmful of the engine block. These particles are so small that they can easily enter our body. For your information, it is Peugeot who invented the FAP. The catalyst has the role of reducing the dose of particles produced from the engine block, then the particle filter collects the waste. It is therefore necessary to have a particle filter in good working condition if you no longer want the Volkswagen 1200 to contaminate the air you inhale.
Why the FAP indicator light on your Volkswagen 1200
The FAP of your Volkswagen 1200 is clogged
Indeed, this is the most common problem. In fact, the particle filter becomes dirty over time. The particles pile up and prevent the flow of exhaust gases. Normally, the particulate filter on the Volkswagen 1200 should be cleaned by itself and thus remove this soot. On the other hand, if this one is particularly old it will have to be changed.
An electronic problem
The concern with the LEDs is that you are not sure there is a problem. In fact, it often happens that an indicator light shines while the Volkswagen 1200 turns without worries. The particle filter has several electronic probes which send the message to the indicator. When these sensors have a problem while this particle filter is working perfectly, it is conceivable that the indicator will come on.
What to do if the FAP indicator light on your Volkswagen 1200 lights up?
At first, it is completely forbidden to remove the particle filter on your Volkswagen 1200! Indeed, it is punishable by law. You should check the probes to see if they are working properly. If these ever work perfectly, the dysfunction comes from the FAP. If it turns out to be dirty, you can clean it by driving in the towers for about ten minutes. Without exaggerating, the process may damage the vehicle. It is advisable to drive to 3000 revolutions minutes. The temperature of the engine block will thus roast the stored soot, and clean this particle filter. When this method does not work, it should be changed.
Conclusion:
The damaged particle filter will then pollute as well as cause loss of power. It therefore remains important to change it. Leave us a comment in case our article helped you. See you soon !
