Mercedes-Benz Citan Coil Pack Replacement Parts

Only the petrol-engined Citan variants have a coil pack — these use spark-ignition and require one coil per cylinder. The vast majority of Citans sold in the UK were fitted with diesel engines (the 1.5 CDI unit badged as 108 CDI, 109 CDI, or 111 CDI), and diesel engines do not use coil packs or spark plugs at all, so if your Citan is a diesel you will not find this part because it was never fitted. If you have a petrol Citan — the 1.2-litre turbo petrol unit introduced on the W420 second-generation model from 2022 onwards — then a coil pack is a genuine fitment. Double-check your fuel type on your V5 before searching.

The Citan ran in two main generations: the W415 (first generation, 2012–2021), which was predominantly diesel in the UK and is very unlikely to have a coil pack, and the W420 (second generation, 2022-onwards), which introduced a 1.2-litre petrol turbo variant alongside diesel options. If you have a petrol W420, the generation matters a great deal because the coil pack design is specific to that engine family and will not cross over to the W415 diesel range. Always confirm which generation you have before purchasing.

Citans from 2022 onwards all belong to the W420 generation, so if they share the same 1.2-litre petrol engine code the coil pack is very likely to be compatible within that generation. The engine code is the most reliable guide here — check your V5 or run a VIN check to confirm the exact code before buying from a breaker. Minor ancillary or mounting changes within a production run are possible, so confirm the full engine code with the breaker against your registration to be sure.

No — trim level has no bearing on coil pack fitment whatsoever. The coil pack follows the engine, not the badge or specification level, so a coil pack from a base-specification petrol W420 Citan is drawn from the same engine as one from a Progressive-trim example. The only things that matter are the engine code, fuel type (petrol only), and build year within the generation. Focus on matching those details with the breaker rather than worrying about trim.

If your Citan is a diesel (108 CDI, 109 CDI, or 111 CDI), there is no coil pack fitted and it cannot be the source of your fault. Diesel engines use glow plugs rather than spark plugs and ignition coils, so if you are experiencing misfires, hard starting, or poor running on a diesel Citan the parts to investigate are the glow plugs, glow plug relay, injectors, or fuel system components. Speak to your mechanic about which of those is most likely given your specific symptoms.

The W420 Citan's 1.2-litre petrol engine is closely related to units found in certain Renault models due to the Mercedes-Renault partnership underpinning the second-generation Citan, so there may be engineering overlap. However, whether a specific Renault-sourced coil pack is a direct swap depends on the exact engine code and any differences in ancillary fittings, and this is not something to assume without verification. Confirm the engine code on both donor and recipient vehicles and put the question directly to your breaker, who will be able to cross-reference the part numbers.
