Mercedes-Benz CLA Engine Replacement Parts

The CLA has two main generations: the C117 (2013–2019, facelifted in 2016) and the C118 (2019–present). The engine codes differ significantly between these generations, so knowing which generation you have is the first step — but the engine code itself, found on your V5 logbook or via a VIN check, is the single most useful detail you can give a breaker, as it identifies the exact unit fitted regardless of badge or year.

Both the 2015 and 2017 cars sit within the C117 generation (2013–2019), with the facelift arriving in 2016. Engines sharing the same code within that generation are generally the closest match, but whether ancillary components and mounts changed across the 2016 facelift is something you should confirm with the breaker against your registration, as mid-production changes can catch buyers out. Always match on engine code first.

Yes, it matters — the CLA 200 and CLA 220 use different engine codes and different outputs, so they are not interchangeable even though both are petrol or both diesel variants of the same car. Always match the engine code on the donor car to your own, not the badge; a 220d engine will not simply drop into a 200d without significant changes. Give the breaker your engine code and let them cross-reference rather than relying on the model designation alone.

Trim level — whether SE, Sport, AMG Line, or any other — has no bearing on the engine fitted; these are cosmetic and equipment packages only. What determines the engine is the engine code stamped on the block and recorded on your V5, not the trim badge. When buying a used engine, focus entirely on matching that code and ignore the trim name of the donor car.

No — diesel and petrol engines are entirely different units and are not interchangeable. Fuel type is one of the most fundamental fitment criteria for any engine, and fitting the wrong type would require rebuilding the fuelling, exhaust, and management systems around it. Always confirm the fuel type matches your own before approaching a breaker, and provide your engine code so they can source the correct unit.

This is an important question but not one any FAQ can answer definitively for your specific car — you should confirm with the breaker and your fitting garage whether the donor engine's ECU will need coding to your vehicle. Mercedes-Benz engines can involve immobiliser and ECU pairing considerations that vary by year and specification, and getting this wrong can leave a car that starts but does not run correctly. Raise it before purchase so you understand the full scope of the job.
