Frequently asked questions

What is an EGR Valve?

The EGR (Exhaust Gas Recirculation) Valve allows your engine to burn more cleanly and efficiently, reducing dangerous Nitrogen Oxide emissions by 'recirculating' some of the air in your exhaust and re-burning it, creating a more complete fuel burn.
+

How does an EGR Valve work?

All new diesel cars have an EGR Valve fitted as standard. It uses a vacuum pump to suck a controlled amount of exhaust gas back into your car's 'inlet manifold'. Here, it mixes with 'regular' air (pulled in from the car's air filter). This mix of gases actually creates a cooler gas, which leads to a cleaner burn and lower exhaust emissions.
+

What are the symptoms of an EGR Valve problem?

If an EGR Valve becomes blocked or fails to function, you will notice a number of issues including: rough idling, hesitation on acceleration, stalling, increased fuel consumption and more. Your engine management light may also switch on.
+

Can an EGR Valve fault cause 'limp mode' in a car?

This will depend on your car and the engine it has fitted. However, the poor performance and hesitation experienced may 'feel' like your car is in limp mode.
+

Does cleaning an EGR Valve work?

The most common cause of EGR Valve issues is clogging or sticking caused by a build up of soot within the valve. If this is the issue, then it is possible to clean the EGR Valve to return it to working order by removing it, soaking it and cleaning thoroughly with carburetor cleaner. Note, however, that removing and refitting the EGR requires some mechanical knowledge and access under your car.
+

Can an EGR Valve cause stalling?

Yes - EGR Valve faults cause all sorts of 'rough running' issues, including stalling.
+

How much to fix an EGR Valve?

In our experience, garages will be able to remove, clean or replace, and refit an EGR valve from £150 to £250.

ERG Valve Repair Prices/What is an ERG Valve?

ERG stands for Exhaust Gas Recirculation and it is a function performed within the combustion engine of a car. The measure is sophisticated in the manner in which it is carried out as exhaust gasses are recirculated back into the inlet manifold to be used for combustion again.

The reason that ERG takes place is to reduce the production of oxides of nitrogen which is harmful to breathe in and is damaging to the environment.

The impact of exhaust gas being recirculated is a drop in engine performance and fuel economy. Diesel cars are also subject to an increase in the production of soot and harmful particulates. However, new engines are able to utilise a variety of clever electronic control strategies to reduce the impact of using an EGR system.

At the heart of the ERG system is the ERG valve, a part which has evolved over time to be more efficient and effective. For example, the part used to be pneumatically operated which limited it to only an 'open' or 'close' setting, however, the ECU (Engine Control Unit) is used to allow continuous levels of adjustability in new models.

A ERG valve has to be highly robust as exhaust fumes travel through at extremely high temperatures and velocity. There is also a high volume of soot and particulate matter carried by the fumes and as it has not passed through the DPF, it can build-up in the ERG system, causing problems.

ERG Valve Problems

When there is a build-up of soot and particulate matter, the EGR valve can become stuck open or closed as the substance can become tar like. A blocked EGR valve could be the cause of the engine light in your car switching on as the engine emissions system will not be performing properly.

Wiring and pneumatics could be the root cause of ERG problems as the communication between the ERG valve and ECU may be compromised.

This can be a difficult problem to diagnose as the ERG valve is not the most common cause of the engine warning light coming on and mechanics may not decide to look at the part until after checking more obvious potential causes.

However, using an intelligent diagnostic tool which connects directly to the ECU in your car, a mechanic may be able to see the problem immediately.

However, the ECU will only be able to tell if there is an ERG problem if there is a total failure. It will not be able to detect degradation.

If the ERG valve is stuck open, your car will suffer from a rough idle and a drop in engine performance as well as a decrease in fuel economy.

If the ERG valve is jammed shut, there may be an increase in the temperature within the cylinder which may lead to engine knocking. Fortunately, modern cars are fitted with knock sensors which will enable the car to adapt accordingly.

Replacing an EGR Valve

If your car needs to have its EGR valve removed, you will have to pay for a new part and the labour time of the mechanic. Fortunately, this is not the most complex of repairs as the part is not usually buried too deeply within a car engine.

However, the only way to know how much an ERG valve replacement will cost on your specific car is by getting a range of quotes from the best local mechanics.
