Used Peugeot 508 EGR Valve

Yes, most Peugeot 508s are fitted with an EGR (exhaust gas recirculation) valve, but only on diesel and petrol engines where the system is used to reduce NOx emissions — which covers the vast majority of 508 variants sold in the UK. The 508 was launched in 2011 and has been offered almost exclusively with turbocharged diesel engines (the HDi/BlueHDi family) alongside some turbocharged petrol units, and all of these carry an EGR valve as standard. If you are unsure whether your specific engine has one, check your registration against the engine code before ordering from a breaker.

This question spans an important boundary: the first-generation 508 ran from 2011 to 2018 with a facelift around 2014, and the shift from Euro 5 to Euro 6 emissions standards falls within that period, typically affecting cars registered from September 2015 onwards. An EGR valve from a 2013 Euro 5 car and one from a 2016 Euro 6 car may look similar but are likely calibrated differently and may not be interchangeable, even on the same engine displacement. Always confirm with the breaker, giving them your exact engine code and registration, before purchasing.

Trim level makes no difference to EGR valve fitment on the Peugeot 508 — the valve is determined entirely by engine code and emissions era, not by whether the car is an Access, Active, Allure or GT. A GT 508 on a 2.0 BlueHDi engine will use the same valve as an Active on the same engine code from the same period. When sourcing from a breaker, focus on matching the engine code and registration year rather than trim.

The second-generation 508 launched in 2018 with a significantly updated engine line-up, moving fully to BlueHDi diesel units and newer petrol engines compared to many first-generation variants, so the EGR valves are not expected to be interchangeable across this generation boundary. Even where engine displacements appear similar, the calibration, pipe connections and sensor configurations can differ. Confirm with the breaker using your exact registration and engine code to avoid an expensive mistake.

No — the body style, whether saloon or SW estate, has no bearing on EGR valve fitment, as the valve sits within the engine bay and is identical across body styles sharing the same engine. What matters is the engine code, fuel type and the emissions standard (Euro 5 or Euro 6) the car was built to. Give the breaker your registration and engine code and they can confirm the correct unit regardless of which body style your 508 is.

The year matters significantly, because the 1.6 HDi engine family was updated over the 508's production life to meet changing emissions standards, and the EGR valve specification changed alongside those updates. A valve from an early Euro 5 1.6 HDi may not be a direct swap for one from a later, more refined version of the same displacement. Always supply the breaker with your full engine code (stamped on the engine block or visible on your V5C) alongside your registration to ensure the part matches your specific calibration.
