What is a DPF on your smart fortwo for?

As its designation presages, it is used to filter out microscopic particles toxiques of your engine block. These kinds of molecules are so tiny that they can easily enter your body. It is also Peugeot who invented the FAP. Your catalyst is used to limit the dose of particles produced from the engine block, then the FAP collects the surplus. It therefore remains essential to have a particle filter in good working order if you no longer want the smart fortwo to pollute the environment.

Why the FAP indicator lights up on your smart fortwo

The FAP on your smart fortwo is clogged

Here is the most common malfunction. No worries, your FAP becomes clogged over time. Particles form clusters and then impede the flow of exhaust gases. Ordinarily, the FAP in the smart fortwo is supposed to clean itself and thus remove this soot. However, if the latter is old it will have to be changed.

An electronic problem

The problem with these LEDs is that you are by no means sure that there is a malfunction. In fact, it often happens that an indicator light comes on while the smart fortwo works without problems. The FAP has electronic sensors which send the warning towards the indicator. If the probes malfunction while the FAP is working perfectly, it is plausible that the indicator light comes on.

What to do if the FAP indicator on your smart fortwo lights up?

First of all, it is perfectly forbidden to remove the particulate filter from your vehicle! This is an offense. You will be able to examine the probes to see if they are working properly. If these ever work well, the malfunction comes from the Particle filter. If the latter was dirty, it can be unclogged by rolling in the towers for about 10 to 15 minutes. Don't accelerate too much either, it could damage the car. We advise you to drive to 3000 rpm. The heat of the engine should thus carbonize these stored dirt, and therefore purify the FAP. When such a combination is not suitable, it will have to be replaced.
