Second Hand Mercedes-Benz Citan Exhaust Manifold

The Citan uses engines shared with the Renault Kangoo platform, and on these engines — particularly the 1.5 dCi diesel units — the exhaust manifold is cast integrally into the cylinder head rather than being a separate, bolt-on component. This means there is no standalone exhaust manifold to source as a used part; if you have an exhaust-related fault, what you are most likely looking for is either the cylinder head itself, the turbocharger inlet pipe, or a front exhaust pipe and downpipe assembly.

Because the manifold is integral to the cylinder head on Citan diesel engines, the parts most commonly needed for exhaust-related repairs are the turbocharger, the front exhaust pipe or downpipe that connects from the turbo outlet, and further back the mid-pipe, DPF, and rear silencer depending on which section has failed. If your issue relates to gases escaping near the engine, the cylinder head or turbo gaskets are worth investigating rather than a separate manifold. Ask your breaker to confirm exactly which section is relevant to your fault before ordering.

Yes, the W415 first-generation Citan (2012–2021) and the W420 second-generation Citan (2022 onwards) use different underpinnings and different engine families, so exhaust components including downpipes and DPF assemblies are not interchangeable between the two generations. Even within the W415, emissions-era differences between Euro 5 and Euro 6 variants affect which exhaust components are fitted, particularly around the DPF and associated pipework. Always give your registration to the breaker so they can confirm the correct engine code and emissions standard before supplying any part.

Almost certainly not without modification — Euro 6 Citans have additional after-treatment components and different pipework routing compared to Euro 5 vehicles, and fitting the wrong era's parts could cause failure of emissions-related systems and an MOT failure. The engine code on your vehicle is the most reliable way to confirm which specification you have, and you should give this to the breaker alongside your registration. Confirm with the breaker against your registration whether any specific pipe or after-treatment component crosses the Euro 5 to Euro 6 boundary safely.

No, trim level does not affect exhaust component fitment on the Citan; what matters is the engine code, fuel type, and emissions era rather than whether the vehicle is a panel van, crew van, or Tourer passenger variant. A 1.5-litre diesel downpipe from a van-spec W415 will reference the same engine as a Tourer-spec W415 with the same engine code. Focus your search on matching the engine code and Euro standard rather than the trim name.

Both a 2018 and a 2015 Citan fall within the W415 first-generation range (2012–2021), so they share the same broad platform, but you need to confirm that both vehicles carry the same engine code and the same emissions standard before assuming the downpipe will interchange. The W415 spanned both Euro 5 and Euro 6 variants, and the year boundary between those standards means a 2015 vehicle may be Euro 5 while a 2018 vehicle is likely Euro 6, with different exhaust geometry. Confirm with the breaker against both registrations to be sure the part is a genuine match.
