When to change the EGR valve?

The EGR valve in your vehicle is a device designed to reduce pollutant emissions from your vehicle. All new vehicles are equipped with an EGR valve. Here in this article are all our tips on when to change the EGR valve!

🚗 What is the role of the exhaust gas recirculation valve?

When to change the EGR valve?

The EGR valve, which stands for Exhaust Gas Recirculation, is an important part to limit the pollution of your vehicle. Indeed, with stricter regulations on nitrogen oxides emissions (Euro 6 standard), all vehicles are now equipped with an EGR valve to remove as many particles as possible.

Its operation is relatively simple: an exhaust gas recirculation valve allows some of the exhaust gases to be redirected to the engine in order to burn the remaining particles rather than throw them into the atmosphere. Thus, this second combustion of the exhaust gas reduces the amount of emitted particles as well as the amount of nitrogen oxide (NOx).

Thus, the exhaust gas recirculation valve is located between the exhaust manifold and the intake manifold. It consists of a valve system that allows you to regulate the amount of gas injected into the engine.

However, the exhaust gas recirculation valve has only one serious problem: engine contamination. Indeed, in the long term, the EGR valve can clog your injectors and become clogged with carbon deposits. Therefore, it is important to properly maintain your EGR valve to prevent clogging: if your EGR valve is blocked in the closed position, your car will pollute much more, if it is locked in the open position, the intake system can be damaged and clogged. quickly. So be sure to check if your emission control system is working.

?? What are the symptoms of a dirty or clogged EGR valve?

When to change the EGR valve?

As we just saw, your EGR valve has a high risk of clogging and clogging if you don't service it regularly. There are several symptoms that can alert you to a malfunctioning EGR valve:

  • Engine settings;
  • Unstable engine idle speed;
  • Loss of power during acceleration;
  • Emissions of black smoke;
  • Excessive consumption of gasoline;
  • The anti-pollution indicator light is on.

If you are experiencing any of its symptoms, it is possible that your EGR valve is clogged and dirty. We advise you to quickly go to the garage to clean or replace the EGR valve so as not to damage the engine and injection system.

🗓️ How to extend the service life of the exhaust gas recirculation valve?

When to change the EGR valve?

On average, an exhaust gas recirculation valve has a service life of about 150 km. However, the exhaust gas recirculation valve can quickly become clogged depending on your driving style. Indeed, if you only drive in urban conditions at low speeds, your exhaust gas recirculation valve will clog up very quickly, because this is where the engine produces the most carbon and pollutants.

Thus, there are basically 2 solutions to maximize the life of the EGR valve and avoid clogging. First, descale the engine and exhaust system regularly. In fact, descaling allows for thorough descaling by injecting the cleaner directly into the exhaust system.

Finally, the second solution is to regularly drive at high speed on the highway to remove carbon and regenerate the diesel particulate filter and catalyst. In fact, as your engine revs up, it burns and removes the carbon stuck in your injection or exhaust system.

You can find our guide on how to clean the exhaust gas recirculation valve or replace the exhaust gas recirculation valve yourself. Indeed, remember to first clean the EGR valve before replacing it, because in most cases the EGR valve works, but only clogged and dirty.

?? How much does it cost to replace an exhaust gas recirculation valve?

When to change the EGR valve?

On average, expect between € 100 and € 400 for an exhaust gas recirculation valve replacement. However, the cost of replacing an exhaust gas recirculation valve varies greatly depending on the type of valve and its location. Indeed, on some car models, labor costs are more due to the difficulty of accessing the EGR valve.
