The DPF indicator light comes on and you don't know what the problem is. DPF is found more in cars Diesel, even though they can now be found in petrol cars. Just before you get into repairs in the Hyundai Neos 2, it is still wiser to understand where the problem comes from. What is a DPF used for? Why is the light on? What are the most regular problems? In this text, we will do a point by point guide. 
What is a FAP used for on your Hyundai Neos 2
As its designation suggests, it is used to filter out microscopic molecules toxiques of the motor. The particles are so tiny that they can easily enter your body. It should be noted that it is Peugeot who developed the FAP. The role of the catalyst is to reduce the level of molecules generated from the engine, and the particulate filter collects the rest. It is therefore essential to have an operational particle filter in the event that you do not want the Hyundai Neos 2 to pollute the environment.
Why the DPF warning light comes on on your Hyundai Neos 2
The FAP of your Hyundai Neos 2 is clogged
Indeed, it is the most frequent problem. No wonder the particulate filter gets clogged over time. These molecules accumulate and then thwart the flow of your exhaust gases. At first glance, the particulate filter on the Hyundai Neos 2 can purge itself and remove clumps. Unfortunately, if this one is particularly old it will have to be changed.
An electronic problem
The problem with indicator lights is that you are never sure you have a problem. In practice, it sometimes appears that an indicator light is on while the Hyundai Neos 2 is running without problem. This particulate filter has several electronic sensors which send a warning to the dashboard. If your probes have a problem while your particulate filter is working perfectly, the indicator light is likely to go off.
What to do if the DPF warning light on your Hyundai Neos 2 comes on?
At first, it is completely illegal to remove the particulate filter on your vehicle! It is considered a crime. You should check the probes to see if they are working properly. If these are working perfectly, the problem must come from the DPF. If the latter was filthy, you will be able to scrub it by driving in the towers for 10 to 15 minutes. Do not accelerate too much either, it could damage the engine. We advise you to go up to 3000 rpm. The temperature of the engine block will cause the soot encrusted to roast, and thus purify the particulate filter. If this manipulation does not work at all, it will have to be changed.
Conclusion:
The damaged fap will pollute and decrease acceleration. It is therefore necessary to replace it. Leave a comment if our article was helpful. Enjoy the road!
