Compare Mitsubishi EGR valve repair quotes from specialist garages

Mitsubishi's automotive division was founded in 1970, but it produced its first vehicle way before that. In 1917, the shipbuilding division created the Model A, intended as a luxury car for officials. It was the first series-production vehicle in Japan and paved the way for the Debonair, a four-door executive sedan introduced in 1964.

A breakthrough happened for the company in 1976 when it developed Silent Shaft engine technology to reduce vibrations. This technology was so successful that it was licensed to other brands, including Porsche and Fiat.

Since then, Mitsubishi has continued to push boundaries. Its 2011 Outlander ad campaign beat no less than five world records, including the greatest distance driven by a vehicle in reverse on snow in 30 seconds.

EGR stands for exhaust gas recirculation. The EGR valve links the intake manifold and the exhaust manifold. It plays a vital role in helping to reduce the amount of NOx emitted from a car. Learn more about how it works here.

Over time, EGR valves can become clogged due to a build-up of soot, and when this happens, an EGR valve clean or replacement is required. Common symptoms of an EGR fault include rough idling, erratic engine functioning (including stalling), increased fuel consumption and higher emissions.

Some manufacturers recommend using an EGR cleaning service every 50,000 miles; doing so helps prevent performance issues and extends the component's life.

EGR valves typically have a lifespan of around ten years. After this time, it's best to book an EGR valve replacement if you experience any of the symptoms listed above. A stuck EGR valve will speed up the process of the diesel particulate filter (DPF) becoming blocked.
