Second Hand Mercedes-Benz E-Class EGR Valve

Yes, but only on diesel-engined variants — the EGR (exhaust gas recirculation) valve is fitted to diesel E-Class models including those with the OM646, OM651, OM642, and related engine families, and is not present on petrol variants, which use different emissions management systems. If your E-Class is petrol, you will not have an EGR valve to replace. Check your V5C or use your registration on an online data checker to confirm your engine type before searching.

The W211 (2002–2009) and W212 (2009–2016, facelift 2013) are different generations with different diesel engine families, so an EGR valve from a W211 is very unlikely to be a direct fit on a W212 even if both cars are diesel. The critical matching factor is the engine code — for example, an OM651 unit from a W212 will not interchange with an OM646 unit from a W211. Always confirm the engine code with the breaker against your registration before purchasing.

The W212 facelift arrived in 2013, and while the core diesel engines carried over, there were revisions that can affect ancillary components including EGR systems, particularly around Euro 5 and Euro 6 emissions boundaries. A valve from a pre-2013 W212 may not be a straight swap onto a post-2013 car, and fitting a part from the wrong emissions era could cause running issues or an MOT failure. Match by engine code and confirm the specific part number with the breaker against your registration.

No, trim level has no bearing on EGR valve fitment — SE, Sport, Avantgarde, and AMG Line variants with the same diesel engine code all use the same EGR valve. The part follows the engine and emissions specification, not the interior or exterior specification of the car. You may find cosmetic differences between breakers' donor cars, but the EGR valve itself will be identical across trims sharing an engine code.

The W213 generation launched in 2016 and introduced updated diesel engines predominantly to Euro 6 standards, while the W212 ran largely to Euro 5 — these are different emissions eras with different EGR valve designs, and cross-generation fitment is not recommended. Even where an engine code appears similar, the EGR valve and associated pipework may differ in ways that prevent correct fitment or cause emissions faults. Provide your exact engine code and registration to the breaker to ensure they supply the correct unit.

Yes — the S212 estate and W212 saloon share their engine and drivetrain components, so diesel variants with the same engine code use the same EGR valve regardless of body style. The EGR valve is determined entirely by the engine code and emissions specification, not by whether the car is a saloon or estate. Confirm your engine code with the breaker to be certain, as there were multiple diesel engine options across the W212 range.
