Our expert insights into EGR valve replacement
What does an EGR Valve motor do?
The valve controlling your EGR (exhaust gas recirculation) controls the amount of nitrogen oxide emitted into the atmosphere by engines by recycling part of the exhaust gas back into the engine cylinders.
What are the symptoms of a malfunctioning EGR Valve motor?
A rough idle when starting your vehicle or during brief stops (i.e. low engine speeds with a warmed-up engine) can be caused when the EGR is constantly open and a continuous flow of exhaust gases goes into the intake manifold. Poor performance can be caused when the valve is open or closed. The incorrect function of the EGR valve can cause the erratic performance of your vehicle.
What happens when we do an EGR Valve Replacement replacement on your car?

The valve controlling your EGR (exhaust gas recirculation) is an important part of your car's engine. It controls the amount of nitrogen oxide emitted into the atmosphere by petrol and diesel engines by recycling part of the exhaust gas back into the engine cylinders.
Lexus
Lexus is the luxury division of the Japanese automotive manufacturer Toyota.
The Lexus brand was launched in 1989, is marketed in more than 70 countries worldwide, and has become Japan’s largest-selling make of premium cars.
How popular is Lexus in the United Kingdom?
For such a high-flying global leader, Lexus has a seemingly modest 156k cars on the road in the UK today.
Luxury executive vehicles for the discerning driver
In the UK, the Lexus brand focuses heavily on the NX and RX SUV models, it’s the fastest growing market for family cars after all; but each of the hatchbacks, saloons and coupés in its range come with the same high-level of luxury and sophistication for their £25–£76k price tags.
Lexus design and technology
Lexus was born to present itself as a luxury brand, something Toyota wasn’t in a position to market to their typical customer given their existing brand perception. To achieve a true luxury standard, they have targeted both vehicle development as well as their lavish presentation.
‘Lexus Musts’
Each vehicle has to achieve 500 specific must have standards known as ‘Lexus Musts’, all of which are to attain the high-end presentation and performance of a ‘true’ luxury marque.
Although they might not all be ‘Lexus Musts’ you can expect to find criteria such as leather seat stitching, smart key entry, remote touch control systems, surround sound and reduced cabin noise that utilises acoustic glass, in your Lexus vehicle. And the driving technology is just as impressive: Lexus introduced continuously variable transmissions, regenerative brakes, hybrid and electric fuel options, as well as vehicle stability and integrated dynamic handling management systems.
How common is an EGR valve replacement?
With exhaust gases flowing through the component, it will eventually succumb to the deposits of carbon and hydrocarbons and it will ultimately seize. Replacing an EGR valve is an all too common repair.
How does an EGR valve work and what are the components?
The EGR valve is connected to the exhaust system by a metal tube. When the engine is running, the valve will be opened by the engine management system to allow the exhaust gases to travel up the tube from the exhaust system and back through into the inlet manifold, and afterwards back into the engine. The control of this valve is either driven directly by a solenoid on the EGR unit itself or via a hose to a solenoid on the vacuum circuit that is also opened by the engine management system. Some EGR units have a cooler as part of them, that is plumbed into the engine’s cooling system, literally to cool the exhaust gasses before they go back through. By the exhaust gasses going back into the engine, it reduces NOx (Nitrogen Oxide) content. This is because the exhaust gas reduces the actual oxygen proportion and increases the vapour content, which in return reduces the combustion temperature peak. As more NOx is produced as the temperature rises, this method actively reduces the amount created.
What are the symptoms of a malfunctioning EGR Valve motor?
A rough idle when starting your vehicle or during brief stops (i.e. low engine speeds with a warmed-up engine) can be caused when the EGR is constantly open and a continuous flow of exhaust gases goes into the intake manifold. Poor performance can be caused when the valve is open or closed. The incorrect function of the EGR valve can cause the erratic performance of your vehicle.
