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.

High-quality EGR valves and emission control parts – durability and efficiency

High-quality EGR components – precise operation and engine safety

EGR (Exhaust Gas Recirculation) valves and parts are key components of the exhaust gas recirculation system, helping to reduce harmful gas emissions into the atmosphere. They redirect some of the exhaust gas back into the engine cylinders, lowering combustion temperatures and reducing nitrogen oxide (NOx) emissions. At Global Parts, you'll find a wide selection of used car parts. , including EGR valves and parts, ideal for BMW , Audi , Mercedes , Volkswagen , Mini and others .

Definition and meaning of EGR valve

The EGR valve is a component that controls the flow of exhaust gases, which in modern engines is electronically controlled by the ECU. In petrol engines, EGR valves typically operate at a recirculation rate of 5–15%, while in diesel engines, these values can reach up to 50%. This allows the system to meet the stringent Euro 5 and Euro 6 emission standards, which is crucial for vehicles manufactured after 2014.

What are the functions of EGR valves and parts ?

EGR valves and components play a key role in the exhaust and combustion system: Reducing exhaust emissions – The EGR system reduces harmful nitrogen oxide emissions by redirecting some of the exhaust gases back into the cylinder. Improved engine efficiency – Exhaust gas recirculation makes the combustion process more uniform, which can result in fuel savings. Environmental protection – The EGR system helps meet exhaust emission standards, which is especially important in modern vehicles. Cooperation with other systems – EGR valves work in conjunction with sensors and controllers, ensuring optimal engine control.

EGR valve types

There are three main types of EGR valves available on the market:

Mechanical (pneumatic) – used in older car models, controlled by vacuum.
Electric – they use stepper motors and position sensors, which allows for greater precision of operation.
Liquid-cooled – in vehicles meeting higher emission standards, exhaust gases directed through the EGR valve are additionally cooled in a special heat exchanger.

Why is it worth taking care of EGR valves and parts ?

Neglecting maintenance or damaging EGR valves and components can lead to serious engine and emissions problems. Typical symptoms include: Loss of engine power – A dirty or damaged EGR valve can cause the engine to run erratically. Higher fuel consumption – A malfunctioning EGR system can lead to less efficient fuel combustion. Smoke and unpleasant odors – EGR valve failure can cause increased black exhaust emissions. Dashboard Errors – Problems with the EGR system may be indicated by the check engine light. At Global Parts, we offer original used EGR valves and parts that have undergone extensive quality testing, ensuring their reliability and functionality.

Symptoms of a damaged EGR valve - table

Symptom	Possible causes	Compatibility problem
Engine power loss	Valve stuck in the open position	It is found in both diesel and petrol engines.
Rough idling	Excessive carbon deposits on the valve disc	Typical for diesel engines
Smoking black	Lack of proper exhaust gas recirculation	Most common in TDI and CDI
Higher fuel consumption	Inaccurate valve closing	Applies to models with electric EGR

How to choose the right EGR valves and parts ?

When selecting EGR valves and parts, there are several key aspects to consider: Vehicle-specific fit – Each exhaust gas recirculation system is specific to a given model and engine type. At Global Parts, you'll find EGR valves and parts perfectly matched to BMW , Audi , Mercedes , Volkswagen , Mini , and more . Technical condition – Used EGR valves and parts should be free from excessive dirt, corrosion and mechanical damage. EGR System Type – Depending on your vehicle, you may need mechanical valves, electric valves, or water-cooled systems.

EGR valve compatibility with popular models

For example:

The Volkswagen Golf VI 2.0 TDI uses a water-cooled EGR valve to meet the Euro 5 standard.
The Mercedes-Benz C-Class (W204) with CDI engine uses an electronic EGR valve for precise emission control.
The BMW 3 Series E90 in the 320d version has an EGR valve integrated with the exhaust gas cooler, which increases the efficiency of the system.

Why choose used EGR valves and parts ?

Used car parts , such as EGR valves and parts, are a practical solution that allows you to save money while maintaining high quality. By choosing used EGR valves and parts, you gain: Lower costs – Used components are much cheaper than new ones, but offer equally high quality. Ecology – Recycling car parts supports environmental protection and reduces waste. A wide range – In our store you will find EGR valves and parts for the most popular car brands.

How to take care of EGR valves and parts ?

To ensure that EGR valves and parts function reliably for a long time, it is worth following a few rules: Clean your EGR valves regularly to remove carbon deposits and buildup that can reduce their performance. Use high-quality fuel and change air and fuel filters regularly to reduce contaminants in the system. Monitor the operation of the exhaust gas recirculation system and respond to any symptoms of malfunction, such as loss of power or smoke. If you need a replacement, you'll find the right used car parts at Global Parts that will restore full functionality of your EGR system.

EGR valve inspection procedure – step by step

Check diagnostic errors in the ECU using an OBD-II diagnostic computer.
Assess the condition of the valve visually – presence of carbon deposits and dirt.
Check vacuum lines or electrical harnesses.
Clean or replace the valve if necessary.
