Mercedes-Benz Citan Fuel Injector Replacement Parts

Yes, fuel injectors exist on the Citan, but only on variants fitted with a diesel or petrol internal combustion engine – so all standard W415 (2012–2021) and W420 (2021-onwards) Citans will have them, as every engine option across the range is a conventional combustion unit. There are no fully electric Citan e variants that would have no injectors, so for the vast majority of UK Citan owners this is the correct part to search for. If you are unsure, cross-check your fuel type on your V5 before ordering.

Both years fall within the first-generation W415 Citan (2012–2021), so there is a reasonable chance of compatibility, but fitment is determined primarily by engine code rather than year alone – a 2015 and a 2019 van running the same engine code (for example the 1.5-litre diesel OM607 or OM608) are much more likely to share the same injector than two vans from the same year with different engines. Pull your engine code from the V5 or a VIN check and supply it to the breaker so they can match it exactly. Never assume year-to-year compatibility without confirming the engine code matches.

The W420 is a completely new generation launched in 2021 and is based on the Renault Kangoo Van platform, whereas the W415 was based on the older Renault Kangoo generation, so the two share very little mechanically. Even if the displacement sounds similar, the engine codes and injector specifications are very likely to differ across this generation boundary, and you should confirm part compatibility with the breaker against your exact registration and engine code rather than assuming they interchange.

Trim or power-output designations like 108 CDI, 109, 111 CDI, or 112 denote different engine outputs and in some cases different engine codes entirely, so the trim badge absolutely can affect which injector is correct – unlike purely cosmetic trim levels, these Citan designations reflect genuine mechanical differences. A 108 CDI and a 111 CDI may share the same engine family but be tuned differently, which can mean different injector flow rates or part numbers. Always confirm the engine code with the breaker rather than relying on the badge number alone.

Diesel injectors on modern Mercedes-Benz engines, including the common-rail units found in the Citan, often have individual calibration codes that ideally need to be programmed into the ECU for optimal fuelling accuracy, and whether a used injector will work acceptably without coding varies by engine and situation. This is something you must confirm with the breaker and ideally with a Mercedes-specialist or diagnostic technician before purchase, as it falls outside straightforward mechanical fitment. A reputable breaker should be able to advise whether the injector they are supplying comes with its calibration data.

The W415 Citan shares its underpinnings with the Renault Kangoo and the Vauxhall Combo C, and in some cases the diesel engines – such as certain 1.5 dCi units – are common across these platforms, meaning the injectors can sometimes be interchangeable. However, you must match engine codes precisely, as Mercedes may have specified different injector variants even on what appears to be the same base engine, and any ECU calibration requirements may differ between brands. Confirm the engine code from your V5 with the breaker before buying from a Kangoo or Combo donor vehicle.
