Second Hand Mercedes-Benz CLS Exhaust Manifold

These are two different generations — the first-generation CLS (C219) ran from 2004 to 2010, while the second-generation CLS (C218) launched in 2011 — so you are crossing a significant platform boundary and the manifolds are very unlikely to be interchangeable. Even within each generation, fitment depends primarily on engine code, so a 350 petrol manifold will not cross to a 320 CDI diesel. Confirm the engine code on both vehicles with the breaker before ordering, as mixing generations is high-risk.

No — despite both being diesel variants, the 320 CDI and 350 CDI use different engine codes (OM642 family variants that differ in displacement and tune), and their exhaust manifolds are not the same part. Always match by engine code rather than by badge or fuel type alone. Ask your breaker to cross-reference both engine codes before supplying a used manifold.

Trim level does not affect exhaust manifold fitment on the CLS — what matters is the engine code, fuel type, and emissions era. However, AMG variants (such as the CLS 63 AMG) use entirely different engines to standard trim cars, so an AMG manifold will not cross to a non-AMG car and vice versa. As long as the engine codes match, a manifold from a base-spec car will fit a Sport or AMG Line car with the same engine.

The C218 ran from 2011 and received a facelift in 2014, after which some engine variants were updated to meet tightening Euro 6 emissions standards — and these updates can affect exhaust manifold specification. If both cars share the same engine code and emissions standard (Euro 5 or Euro 6), fitment is more likely, but crossing the 2014 facelift boundary is enough of a grey area that you should confirm against both registrations with your breaker rather than assume compatibility.

Yes, the CLS does have an exhaust manifold — all engine variants, both petrol and diesel, produce exhaust gases that must be collected from the cylinder head and routed downstream, so the manifold is a genuine part on this car. On some variants the manifold and catalytic converter are integrated into a single assembly, which affects what a breaker will supply as a used unit. Whether a separate manifold or a combined manifold-cat assembly is correct for your specific engine is something to confirm with the breaker against your registration, as interchange specifics for integrated catalyst units vary.

The first-generation CLS (C219) covered 2004 to 2010, so your 56-plate car falls within that generation, which is a good starting point. Fitment within the C219 range still depends on engine code — for example, a 500 petrol manifold will not fit a 280 CDI — so you need to match on engine code, not just generation. Give your breaker the full engine code from your V5C or door sticker to get the right unit.
