Compare Lexus EGR valve repair quotes from specialist garages

Lexus is known for making luxury vehicles designed according to its defining philosophy: "the pursuit of perfection". In the 2023 Auto Trader New Car Awards, it was voted 'Most Reliable Brand' for the fourth time, maintaining its status as a top manufacturer in the UK.

With several cameos in TV shows (notably Breaking Bad, Silent Witness and Modern Family) and mentions in hip-hop songs (Ignition by R. Kelly and Jay-Z's Somewhere in America), this is a brand deeply ingrained in pop culture.

Lexus has also made waves in the world of motorsport, becoming the first manufacturer to enter a production hybrid car - the Rx 400h - in the Nurburgring 24-hour race.

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.
