Your particle filter indicator light turns on and you do not know what is causing the problem. The particle filter is more often found in cars Diesel, even though we will see more and more of them in petrol cars. Before attempting repairs in your Lancia Delta 2 Hf, it is essential to understand what causes this concern. How does a FAP work? Why is the light on? What can be the most frequent concerns? In this text, we will go around the question. 
What is a DPF on your Lancia Delta 2 Hf
As its name suggests, it is used to purify microscopic molecules harmful of the vehicle. These molecules are so small that they easily enter your body. For information, it's Peugeot who developed this FAP. Your catalyst's role is to lower the level of molecules produced by the engine block, then the particle filter collects the remains. It is therefore essential to have an operational particle filter in case you do not want your Lancia Delta 2 Hf to contaminate the air you breathe.
Why the FAP indicator light on your Lancia Delta 2 Hf
The FAP of your Lancia Delta 2 Hf is clogged
This is the most common problem. In fact, the particle filter becomes blocked over time. The molecules pile up and then block the flow of these exhaust gases. In principle, the particle filter in your Lancia Delta 2 Hf is supposed to purge automatically and therefore expel this soot. That said, if it is too old it must be replaced.
An electronic problem
The problem with these LEDs is that you are not sure if you have a problem. For example, it happens regularly that an indicator light flickers while your Lancia Delta 2 Hf is working perfectly. This particle filter has electronic sounders which send a message to your dashboard. When your sounders do not work well while this particle filter works properly, it is conceivable that the indicator light turns on.
What to do if the FAP indicator on your Lancia Delta 2 Hf lights up?
Above all, it is totally forbidden to remove the fap from your Lancia Delta 2 Hf! Indeed, it is a crime. You can check the probes to see if they are working properly. If these work well, the problem comes from the FAP. If it was dirty, it can be unclogged by rolling in the towers for 10 minutes. Do not accelerate too much either, it may damage the vehicle. We advise you to drive at 3000 rpm. The temperature of the engine block will therefore burn out this stored soot, and therefore clean this particle filter. If this technique does not work, it is necessary to replace it with a new one.
Conclusion:
A damaged particle filter will then pollute but also decrease acceleration. It is therefore important to have it changed. Leave a comment if our article helped you. See you soon !
