Used Mercedes-Benz CLA EGR Valve

Yes, but only on diesel-engined CLA models — the EGR (Exhaust Gas Recirculation) valve is a standard component on diesel engines to reduce NOx emissions, so if your CLA has a diesel engine (such as the 2.2-litre CDI/d units) it will have one. Petrol-engined CLAs do not use an EGR valve in the same way and are very unlikely to need this part. Check your V5C or registration plate lookup to confirm whether your CLA is diesel before searching.

The CLA ran in two distinct generations: the C117 (first generation, 2013–2019, with a facelift in 2016) and the C118 (second generation, from 2019 onwards). These generations use different engine families and different EGR valve designs, so a valve from a C117 is very unlikely to fit a C118. Always confirm the engine code with the breaker to match the part correctly.

The first-generation CLA (C117) received a facelift in 2016, and while the core 2.2-litre diesel engine architecture carried over, there can be differences in emissions calibration and associated components across that boundary. Whether the EGR valve is directly interchangeable between a pre-2016 and post-2016 C117 diesel is something you should confirm with the breaker against your specific engine code, as fitment is not guaranteed simply because the generation is the same.

No, trim level has no bearing on which EGR valve you need — the CLA's SE, Sport, and AMG Line trims all share the same engine options, so the EGR valve is determined entirely by your engine code, not your trim. When contacting a breaker, give them your engine code (found on your V5C or under the bonnet) and your registration rather than your trim name. You may find cosmetic differences on a donor car from a different trim, but these have no relevance to whether the EGR valve will fit.

The CLA shares its 2.2-litre CDI/d diesel engines with other Mercedes-Benz models including the A-Class (W176/W177), B-Class, and C-Class, so there is a reasonable chance of cross-model compatibility if the engine codes match exactly. However, emissions-era differences (Euro 5 versus Euro 6) can affect EGR valve design even within the same engine family, so you should confirm the engine code and emissions standard with the breaker before purchasing. Never assume a visually similar valve from another model will be a guaranteed fit.

For diesel CLAs, the most common engines are the 2.2-litre units badged CDI (pre-facelift C117) or d (post-facelift C117 and C118), with engine codes such as OM651 or OM654 — but you must verify your exact code from your V5C or a registration lookup rather than relying on badge alone, as the codes differ between Euro 5 and Euro 6 variants. Giving the breaker your full registration number alongside the engine code will allow them to cross-reference the correct part. Fitting an EGR valve from the wrong emissions era can affect performance and potentially cause issues at MOT.
