A buyer's guide to used Mercedes-Benz V-Class egr valve
No two egr valves are quite the same across different vehicles, so getting the specifics right matters when you buy used, second hand or a replacement. Answer a few quick questions below and breakers will only quote if they have the exact matching part in stock:
- State whether it's petrol or diesel
- State the engine code if known

Fitment questions
Does the Mercedes-Benz V-Class actually have an EGR valve?
Yes, the V-Class uses EGR valves on its diesel engines, which have always been the dominant powertrain choice in this model — the vast majority of UK V-Class vehicles are diesel-powered. The EGR (Exhaust Gas Recirculation) valve is a standard emissions-management component on these diesel units, recirculating a portion of exhaust gas back into the intake to reduce NOx emissions. Petrol-engined V-Class variants are extremely rare in the UK, but some petrol engines can also carry an EGR valve, so confirm your fuel type with your V5C before searching.
Will an EGR valve from a W638 V-Class fit a W639 V-Class?
Almost certainly not — the W638 (1996–2003) and the W639 (2003–2014) are entirely different generations with different engine families, so the EGR valves are not interchangeable. The W638 used older OM601/OM602-family diesels, while the W639 moved to CDI common-rail units including the OM646 and OM642, each with their own specific EGR assemblies. Always match the part to your engine code, which you can find on your V5C or by asking the breaker to check against your registration.
Does an EGR valve from a W639 V-Class fit the newer W447 V-Class?
No — the W447 (2014 onwards, with a facelift around 2019) uses later CDI engines such as the OM651 and OM654, which are entirely different units to those in the W639 and carry different EGR valve designs to meet Euro 6 emissions standards. Even if a valve looks visually similar, fitting a pre-Euro 6 EGR valve to a Euro 6 engine could cause running problems or an MOT failure. Give your engine code and registration to the breaker so they can confirm the correct part for your specific emissions standard.
Does the trim level — Sport, Style, Exclusive, Avantgarde — affect which EGR valve I need?
No, trim level has no bearing on EGR valve fitment for the V-Class — Sport, Style, Exclusive, and Avantgarde are cosmetic and comfort packages that do not change the engine or emissions equipment. What matters is your engine code, fuel type, and the emissions era your vehicle was built to (Euro 5 or Euro 6). Focus on matching those details with the breaker rather than worrying about which trim your van carries.
I have a 2013 V-Class diesel — will a 2015 EGR valve fit it?
This is unlikely to be a straightforward swap because 2013 sits in the final years of the W639 generation (W639 ran to 2014), while 2015 falls into the early W447 generation with different engine variants built to Euro 6 standards. Even within the same generation, engine code differences between the OM646 and OM642 in the W639, for example, mean the EGR valve design can differ. Check your engine code on your V5C and confirm directly with the breaker against your registration before purchasing.
What engine code should I give the breaker when searching for a used V-Class EGR valve?
Your engine code is the most important piece of information — common diesel codes in the W639 include the OM646 (four-cylinder) and OM642 (V6), while the W447 introduced the OM651 and later the OM654. You can find your engine code on your V5C, inside the engine bay on a sticker or plate, or the breaker can look it up from your registration. Giving the breaker your full registration alongside the engine code gives them the best chance of supplying the right valve for your exact engine and emissions specification.
