The FAP indicator light turns on and you don't know where the problem is coming from. FAP is more common in cars Diesel, although they can now be found in petrol cars. Just before starting repairs in the Volkswagen Buggy, it is essential to understand where this malfunction comes from. What is the role of a FAP? Why does the light go on? What are the most frequent dysfunctions? In this article, we will go over the subject. 
What is an FAP on your Volkswagen Buggy
As its designation presages, its role is to filter out microscopic particles toxiques of the vehicle. The molecules are so tiny that they easily fit into your body. Note that this is Peugeot who developed this FAP. Your catalyst is used to reduce the level of particles generated from the engine, while the particle filter collects the remains. It is therefore essential to have an operational FAP if you do not want the Volkswagen Buggy to pollute the environment.
Why the FAP indicator light on your Volkswagen Buggy
The FAP of your Volkswagen Buggy is clogged
Here is the most common concern. No wonder, your particle filter becomes clogged as time goes by. These particles collect and thus prevent the circulation of exhaust gases. Normally, the particulate filter of the Volkswagen Buggy can clean itself and thus remove the clumps. However, if it is too damaged, it must be replaced by a new one.
An electronic problem
The problem with these LEDs is that you are in no way certain that there is a concern. In practice, it often appears that an indicator light is on while the Volkswagen Buggy is running carefree. Your particle filter has a few electronic sensors which transmit a message to the indicator. If these sensors do not work well while the particulate filter is fine, it is plausible that the indicator light is on.
What to do if the FAP indicator on your Volkswagen Buggy lights up?
First, it is perfectly forbidden to remove the particulate filter from your vehicle! It is an offense. You are able to check the sensors to see if they are working properly. Assumed that these work perfectly, the dysfunction comes from the FAP. If the latter was dirty, it can be cleaned by driving at high speed for around 10 to 15 minutes. Do not climb too much in the towers, it can damage the engine. We advise you to drive to 3000 rpm. The engine temperature should therefore carbonize the stored soot and release the particulate filter. When such manipulation does not work, you will have to replace it with a new one.
Conclusion:
Your damaged fap will then pollute as well as reduce the power of the vehicle. It remains essential to change it. Write a comment if our file has been useful. Good road !
