Cheap Mercedes-Benz CLA Coil Pack

Yes, but only on petrol-engined CLA variants — the coil pack is part of the ignition system that petrol engines need to fire the spark plugs. Diesel CLAs (such as those running the OM651 or similar diesel units) use compression ignition and have no spark plugs or coil packs at all, so if you have a diesel CLA you are looking for the wrong part. Check your V5 or run a VIN check to confirm whether your engine is petrol or diesel before searching.

The C117 ran from 2013 to 2019 (with a facelift in 2016) and the C118 replaced it from 2019 onwards, and although some Mercedes petrol engine families carry across generations, the engine code is the deciding factor rather than the generation itself. If your C117 and a C118 donor car share the same engine code — for example both running the M270 or M260 family — there is a reasonable chance of compatibility, but you should confirm this with the breaker against your exact registration before buying, as ancillary fitment and connector changes can occur across a generation boundary. Always supply your engine code, not just the year.

The engine code matters far more than the year — a coil pack follows the engine, not the badge or model year. Within the C117 generation for example, the pre-facelift (2013–2016) and post-facelift (2016–2019) cars could share an engine code and therefore the same coil pack, but you should not assume this without checking. Give the breaker your engine code (found on your V5 or via a VIN check) and they can confirm whether a specific donor car is a match.

Trim and badge names like CLA 200 and CLA 250 reflect different engine variants, so in this case the badge does actually indicate a different engine — the CLA 200 and CLA 250 use different states of tune or different engine codes within the M270 family, which can mean different ignition components. However, trim levels that share the same engine code — such as a standard CLA 200 versus a CLA 200 in a higher specification — will use the same coil pack, because trim and equipment level have no bearing on the ignition system. Always cross-reference by engine code rather than trim name to be certain.

Most petrol CLA engines are four-cylinder units and will have one coil pack per cylinder, so four in total — though some are individual pencil coils and some are a single multi-coil unit, depending on the specific engine. It is common practice to replace all coils at the same time if one has failed, as the others will have the same wear, but this is a decision for you and your mechanic. When buying used, confirm with the breaker how many coils are included and whether they are from the same donor vehicle.

Physically swapping a coil pack is generally a straightforward job that does not involve coding, as coil packs are passive ignition components and do not pair to the ECU in the way that fuel injectors or modules might. However, whether any associated ignition or engine management work is needed on your specific vehicle is something you should confirm with a mechanic or the breaker against your registration, as mid-production changes can occasionally affect how ancillary components interact with the engine management system. A qualified technician can clear any fault codes and confirm the replacement is working correctly after fitting.
