Second Hand Mercedes-Benz Citan Exhaust System

The Citan (W415) ran from 2012 onwards, and the key boundary to watch here is the shift from Euro 5 to Euro 6 emissions standards, which affected the exhaust and emissions hardware on these vans. A pre-Euro 6 system from around 2013 is unlikely to be a straight swap onto a later Euro 6 Citan even if the engine code looks similar, because the pipework, sensors, and after-treatment components can differ. Name the exact engine code and check the emissions standard on your V5C, then confirm compatibility with the breaker against your registration before buying.

The 109 CDI and 111 CDI badges denote different power outputs but can share the same underlying engine family, so the exhaust system may be identical between them — fitment is driven by engine code and emissions spec rather than the power variant badging. Check the exact engine code stamped on your vehicle (visible on the V5C or in the engine bay) and match it to the donor van rather than relying on the CDI number alone. A breaker can cross-reference engine codes to confirm whether the systems are interchangeable.

No — trim level does not affect exhaust fitment on the Citan; the system is determined by engine code, fuel type (diesel or petrol), and the emissions era of the vehicle. Whether your van is a base worker specification or a higher passenger-spec variant, the exhaust routing and components are the same for a given engine. You may notice minor cosmetic differences in how the tailpipe presents at the rear depending on the body variant, but the mechanical system itself is trim-independent.

This is strong confirm-with-breaker territory — DPF-equipped and non-DPF exhaust systems are not straightforward swaps, and fitting the wrong configuration can cause running issues and an MOT failure. Euro 5 and Euro 6 Citans have different after-treatment setups, and even within Euro 5 there can be variation depending on engine code and market specification. Always quote your registration and engine code to the breaker so they can verify the exact emissions hardware on the donor vehicle before supplying the part.

No — petrol and diesel exhaust systems on the Citan are not interchangeable; diesel systems are built around compression-ignition exhaust chemistry and typically incorporate a DPF, whereas petrol systems are configured around a catalytic converter only. The pipe diameters, mounting points, and sensor positions differ between the two fuel types. Always confirm the fuel type and engine code with your breaker to ensure the system matches your vehicle.

The Mercedes-Benz Citan W415 was introduced in 2012, and while there were updates to the range during its production life, the most significant fitment boundary for exhaust purposes is the move from Euro 5 to Euro 6 emissions legislation rather than a cosmetic facelift point. Euro 6 compliance brought changes to the after-treatment system that mean parts from either side of that boundary may not interchange, even on the same engine family. Name the Euro standard shown on your V5C or confirmed by a DVLA check, and ask the breaker to match that standard on the donor vehicle.
