Used Mercedes-Benz C-Class Coil Pack

Yes, but only on petrol-engined C-Class models — coil packs are an ignition component specific to petrol engines, which use spark ignition. Diesel C-Class variants (such as those with C200d, C220d, or C300d badging) do not use coil packs at all, as diesel engines rely on compression ignition instead. If your C-Class is petrol — for example a C180, C200, C250, or C300 with a petrol engine — then it will have one coil pack per cylinder, typically individual pencil-type coils sitting directly on each spark plug.

The W204 and W205 are separate generations with different engine families, so a coil pack from a W204 is very unlikely to fit a W205 even if both are petrol models with similar badging — for example, both may be badged C200 but use entirely different engine codes. The engine code printed on your V5 or obtainable via a VIN check is the most reliable way to confirm compatibility, and you should give this to the breaker rather than relying on the badge alone. Never assume fitment across a generation boundary without the breaker confirming it against your specific registration.

Yes, a 2011 C-Class is a W204, which ran from 2007 to 2014 and received a facelift in 2011, so your car sits in the post-facelift phase. The facelift brought styling updates and some equipment changes, but coil pack fitment is driven by the engine code, not by whether the car is pre- or post-facelift. Share your engine code with the breaker and they can confirm whether there were any running changes to the ignition system around that period that might affect which coil pack suits your car.

No — trim level makes no difference to coil pack fitment on the C-Class. SE, Sport, AMG Line, and other trim grades fitted to the same petrol engine will use identical coil packs, as the ignition system is determined entirely by the engine, not by the trim specification. The main difference you might notice between cars from different trim levels is cosmetic — interior condition, alloy wheels, and so on — none of which affects whether the coil pack will work in your car.

The gearbox type does not affect coil pack fitment — these are engine components and the transmission plays no part in which coil pack your car uses. As long as both cars share the same engine code, the coil pack should be the same unit regardless of whether the donor car had a manual or automatic gearbox. Always confirm the engine code with the breaker to be sure, as the badge alone can cover more than one engine variant.

Individual coil packs are passive components — they do not store vehicle-specific data in the way that an ECU or instrument cluster might, so coding or immobiliser pairing is not generally a concern when fitting a replacement coil pack. That said, if you have any doubts about whether your specific car's setup requires any adaptation after fitting, it is worth confirming with the breaker or a Mercedes-specialist technician before purchase, as production changes can sometimes introduce ancillary differences that are not widely documented.
