Used Mercedes-Benz B-Class Coil Pack

It depends on the engine: petrol-engined B-Class models use coil packs (one per cylinder), while diesel variants do not use coil packs at all because diesels ignite fuel by compression rather than a spark. The B-Class has been sold in both petrol and diesel forms across its generations, so you need to confirm your fuel type before searching — if you have a diesel B-Class, a coil pack is not the part you need.

The B-Class has run across two main generations: the W245 (first generation, 2005–2011) and the W246 (second generation, 2011–2018, with a facelift in 2014). Petrol variants within both generations use coil packs, with the engine code being the most important detail — common petrol codes include the M266 family in the W245 and the M270 family in the W246, but always verify your exact engine code from your V5 or a VIN check rather than relying on the badge alone.

Both the 2013 and 2015 cars sit within the W246 generation, but the 2015 model falls after the 2014 facelift, which can involve ancillary and mounting changes even within the same generation. The key check is whether both cars share the same engine code — if they do, fitment is likely, but you should confirm the specific part number with the breaker against your registration to be sure.

No, trim level does not affect coil pack fitment on the B-Class — SE, Sport, and AMG Line are specification packages that change interior, cosmetic, and comfort features, not the ignition system. What matters is the engine code, which is the same regardless of trim on an otherwise identical car, so focus on supplying your engine code or registration to the breaker rather than your trim name.

Not necessarily — the badge (B180, B200) indicates the power output and sometimes the engine variant, but what actually determines coil pack fitment is the engine code stamped on the block, not the badge on the boot. Two different badge levels can share an engine code and therefore be compatible, or they can have different codes and not be compatible, so always confirm the engine code from your V5 or a VIN check and supply it to the breaker.

Diesel engines do not use coil packs or spark plugs, so if your B-Class is diesel you are most likely looking for a glow plug or glow plug control module, which serve a similar pre-ignition heating function in diesel engines. Check your V5 or a VIN check to confirm your engine code, then ask the breaker for the correct glow plug set for your specific diesel variant.
