Dirt protection error - engine start message - what is it?

If you want to know what the pollution protection error message is, you've come to the right place! Thanks to him, you receive information that the EGR system, fuel filter or FAP or catalytic converter may fail. Find out how to fix it and what to do in case of an Antipollution error!

What is Antipollution Fault?

Modern cars are equipped with numerous technologies and mechanisms designed to improve driving comfort and make urban travel more economical and environmentally friendly. That's why engineers developed the fuel filter, diesel particulate filter and catalytic converter to reduce exhaust emissions and improve driving quality.

On French Peugeot and Citroen cars, drivers often encounter a problem when the Check Engine light comes on and the Antipollution Fault message is displayed. Most often, this means a failure of the FAP filtration system. In the beginning, it is worth checking the Yelos liquid content. If it ends, you can drive about 800 kilometers more, after which the car will go into service mode. At this point, all you have to do is take the car to a mechanic or change the FAP filter and add fluid.

A fouling protection failure is also related to the catalytic converter, so may indicate a worn element replacement or regeneration. Moreover, if you refuel the car with liquefied gas, the lambda probe reads the data incorrectly and in this case the check engine will not disappear, even after replacing the catalytic converter, because after a few hundred kilometers the error code will appear again.

What's more, Antipolution, known to French drivers, can also indicate more serious problems.. Contrary to appearances, it is not only related to the particulate filter or catalytic converter, but can also report problems with timing, injection (especially in the case of cars with a gas installation), fuel pressure or camshaft sensor.

When does the anti-contamination failure message appear?

Antipollutio malfunction is closely related to the operation of the engine. Problems with the particulate filter and the appearance of an amber Check Engine light inform the driver that the engine is running with some problems. At such a time, it is best to take the car to a specialist as soon as possible, who can erase errors and troubleshoot after diagnosis.

However, before the message appears, you may notice some symptoms that should give you food for thought. If your car starts stalling at low RPM, after 2,5 RPM (even below 2 in some cases), and after restarting the car everything returns to normal, you can expect an Antipollution Fault message to appear soon.

The problem occurs when the car has problems with the FAP particulate filter or with the catalytic converter. However, there may be a problem with the pressure regulator and the pressure sensor at the same time.. The problem should not be underestimated, as after some time the engine power may drop sharply, making further movement impossible. As a result, the fuel and air pumps can fail, as well as problems with starting the car and ignition.

Peugeot and Citroen are the most popular cars with Antipollution Fault

In which vehicles are you most likely to encounter an Antipollution error message? In fact, the problem occurs mainly on French Peugeot and Citroen cars. On the forums, drivers most often report breakdowns of the Peugeot 307 HDI, Peugeot 206, and Citroen with a 1.6 HDI 16V engine. These vehicles are characterized by problems with injectors, coils and valves, which can cause problems with fuel pressure, which, in turn, is expressed in the appearance of the Antipollution Fault signal and the appearance of the Check Engine icon.

Car with LPG gas installation - what to do in case of an Antipollution Fault?

If your vehicle has a gas plant, the problem could be the injectors, pressure regulator, or cylinders. In the case of driving on gas, the speed may drop. In such a situation, turning off the car may solve the problem for a while, so that the car can work normally again. In this case, it should be borne in mind that the situation in which the error has disappeared for some time does not mean that the malfunction has been eliminated. If you have a car with gas, it is worth switching it to petrol and see if the problem occurs. This way you will be able to determine where the failure is more or less located.

How to remove the check engine light?

It's good to know that even after finding the error, fixing the problem, and fixing the problem, the check engine light may still be on every time you start the car. That's why it's worth knowing how to disable this control. Fortunately, the whole process is very simple. To do this, remove the clamp from the negative pole of the battery for a few minutes. After this time, the system should reboot with an error code, and the indicator will turn off. 

Now you know what the pollution protection error is and when this error can occur. Remember that in such a situation it is best to leave the car with a mechanic, because ignoring this message can turn into serious problems.
