Compare SEAT EGR valve repair quotes from specialist garages

SEAT was founded in 1950, back when there were only three vehicles for every 1000 people in Spain. A partnership with Fiat brought the company up to speed with the latest car manufacturing techniques, lasting until 1982 when it was sold to the Volkswagen Group.

SEAT has recently won numerous awards; the SEAT Leon was named Best Family Car at the WhatCar? Car of the Year Awards in 2022, and the Terraco won Best Large SUV the year before. SEAT also has approval from the Vatican - in 1982, it created the Popemobile, which Pope John Paul II used on his visit to Spain.

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.
