What is the main function of the EGR valve?

The EGR (Exhaust Gas Recirculation) valve is a component of the exhaust gas recirculation system that is responsible for redirecting part of the exhaust gases back into the combustion chamber to reduce NOx emissions.

How does the exhaust gas recirculation system work?

The EGR system opens the valve under certain engine operating conditions, which allows fresh air to be mixed with some of the exhaust gases and lowers the combustion temperature.

What types of EGR valves are there?

We distinguish between mechanical (pneumatic), electric, and liquid-cooled valves. The choice depends on the engine type and emissions standards.

What are the symptoms of a damaged EGR valve?

The most common are a loss of power, increased smoke, higher fuel consumption and an illuminated check engine light.

Are EGR valves the same in all cars?

No – they differ in design, control method, and technical parameters. Always select the valve for your specific car model and engine.

How much does it cost to replace an EGR valve?

The price depends on the car model – on average from PLN 300 to PLN 800 for a used valve, plus labor costs.

Are used EGR valves compatible with modern engines?

Yes, provided they are properly matched to the engine version and meet OEM compatibility requirements.
