Cheap Mercedes-Benz B-Class EGR Valve

Yes, but only on diesel-engined B-Class models — the EGR (exhaust gas recirculation) valve is part of the emissions system on diesel engines such as the OM607, OM651, and related units fitted to variants like the B180d, B200d, and B220d. Petrol-engined B-Class models (B160, B180, B200 petrol etc.) do not use an EGR valve, so if your car is petrol you will not find this part on it. If you have a diesel, you do need one and the engine code is the key detail to get right when sourcing a replacement.

These are entirely different generations — the W245 ran from 2005 to 2011 and the W246 from 2012 to 2018, and the two generations used different diesel engine families with different EGR assemblies. Even where displacement looks similar on paper, the engine codes differ, the emissions standards differ (the W246 was designed to meet Euro 5 and later Euro 6 requirements), and the EGR valve design changed accordingly. Do not assume cross-generation compatibility; always confirm the part against your specific registration and engine code with the breaker before buying.

Yes, this is an important distinction — the W246 was produced across both the Euro 5 era (broadly 2012–2014 for new registrations) and the Euro 6 era (from around 2015 onward following the facelift), and the EGR system was updated to meet the tighter Euro 6 standards. Fitting a Euro 5-era EGR valve to a Euro 6 vehicle (or vice versa) risks incorrect operation and could cause an MOT emissions failure. Give the breaker your full registration so they can confirm the correct emissions-era part.

No — trim level has no bearing on EGR valve fitment whatsoever. What matters is your engine code, fuel type (diesel only), and emissions era, not whether your car is SE, Sport, AMG Line, or Urban. These trims share the same diesel engines and emissions equipment, so a valve from an SE could in principle come from the same engine family as one from an AMG Line — but always verify by engine code with the breaker rather than by trim name alone.

You should provide your full registration number, your engine code (usually found on a sticker in the engine bay or in your V5C), and ideally confirm whether your car is Euro 5 or Euro 6 — the breaker can normally look this up from your reg. Mileage is useful too, as a high-mileage valve from a well-maintained car is preferable to one of unknown history. The more precise you are upfront, the less risk of receiving an incompatible part.

Some Mercedes diesel engines — for example the OM651 — were used across multiple models including the C-Class, A-Class, and B-Class, which means the EGR valve may be shared across those platforms where the engine code matches exactly. However, engine variants, inlet manifold configurations, and emissions calibrations can differ even when the code looks the same, so cross-model fitment is not something to assume. Route this question directly to the breaker, giving them both your registration and the donor vehicle's registration, and let them confirm compatibility before you commit.
