Compare Alfa Romeo 159 EGR valve repair quotes from specialist garages

Alfa Romeo is a quintessentially Italian carmaker known for the style and elegance of its sporty vehicles. In a 2008 episode of Top Gear, Hammond, Clarkson and May set out to prove that you can't be a proper petrolhead until you've owned an Alfa. The brand's iconic status also stretches beyond the small screen, with its cars appearing in a slew of blockbusters, including The Godfather, The Graduate, Octopussy and The Talented Mr Ripley.

At the 2022 Autocar Awards, the Alfa Romeo Giulia Quadrifoglio was named a future classic, earning praise for being "sublime to drive and beautiful to look at" - a statement that perfectly captures the spirit of the brand.

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.
