Compare Infiniti Q50 EGR valve repair quotes from specialist garages

The Q50 - a mid-sized premium executive saloon introduced in 2014 - is a standout model in Infiniti's lineup. It offers luxury, technology and style, resulting in a model that is easy on the eyes and capable of competing with class-leading rivals like the BMW 3 Series and Audi A4. Top speeds range between 120 and 155 mph.

In the US, where Infiniti is much more prominent, the Q50 is multi-award-winning. In 2021, for instance, it received the AutoPacific 'Vehicle Satisfaction Award' in the Standard Luxury Car category. There is a known problem with the brake pedal feeling spongy in some Q50s; this issue can be resolved by replacing the master cylinder.

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.
