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.

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.
DS
DS is the premium automobile marque of the Groupe PSA. First announced in 2009 by Citroën as its premium sub-brand; it was suggested to be an abbreviation of different spirit or distinctive series. However, in French, the name is considered a play on words, as the translation of déesse becomes goddess in English.
How popular is DS in the United Kingdom?
As a newcomer to the UK market in its own right, there were around 35k DS cars on the roads in the UK by the end of 2018. Whether those figures will continue to rise at the same rate shown since their introduction in 2015, only time will tell.
Looking to provide a standalone marque to initially compete with brands such as Volkswagen and Audi, PSA decided that neither Citroën nor Peugeot would be able to carry the brand strength that would be able to make a serious threat in the market with an elevated price-point at the level of quality and luxury they set out to achieve.
DS: Establishing a new range of upmarket models
To compete with the likes of Audi, BMW and Mercedes-Benz, DS introduced a range of hatchbacks, saloons and SUVs but it’s undoubtedly their supermini city car that is proving the most popular.
The DS3, sold as a 3-door hatchback or a convertible, is available in countless customisation options and also as the subcompact luxury crossover SUV DS3 Crossback. The DS3 was voted Car of the Year by Top Gear Magazine, and first place supermini four times in a row in the JD Power Satisfaction UK Survey.
DS: Don’t be fooled into thinking they’re just a one trick pony
At the other end of the range you’ll find the DS7 Crossback. Here’s a large SUV designed to compete directly with the Audi Q5, the BMW X3 and the Mercedes-Benz GLC; that’s quite a jump for a car that’s built by Citroën.
The models that you’ll find between the DS3 and the DS7 are created with the same style for the market in mind. The DS4, a mixture of hatchback and SUV, and the DS5, a bigger hatchback priced and pitched against the Audi A4, the BMW 3 Series and the Mercedes C-Class saloons.
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.
