The FAP warning light comes on and you do not know what caused the malfunction. FAP mainly exists in cars Diesel, although they can now be found in gasoline cars. Before attempting repairs In the Volkswagen Golf Plus, it remains crucial to know where this concern comes from. What is the role of a particle filter? Why does the light come on?

What is an FAP on your Volkswagen Golf Plus

As its designation suggests, its role is to purify microscopic particles toxiques of the engine block. These molecules are so small that they can easily enter your body. Note that this is Peugeot who developed this particle filter. The catalyst's role is to lower the dose of particles produced by the engine, then the particle filter collects the remains. It therefore seems fundamental to have an operational FAP in case you do not want the Volkswagen Golf Plus to pollute.

Why the FAP indicator light on your Volkswagen Golf Plus

Indeed, this is the most common dysfunction. Indeed, a particle filter becomes blocked the more time passes. These particles form clusters and interfere with the proper circulation of your exhaust gases. In general, the particle filter on the Volkswagen Golf Plus can purge itself automatically and therefore destroy the clumps. However, if this one is particularly old, you must replace it with a new one.

An electronic problem

The concern with these lights is that we are not certain to have a malfunction. Indeed, it often appears that a warning light comes on while the Volkswagen Golf Plus is operating properly.
