Second Hand Mercedes-Benz CLA Fuel Injector

Fuel injectors exist on all petrol and diesel CLA engines, because every internal-combustion engine requires them to deliver fuel into the cylinders. What changes between variants is the injector type — petrol CLAs use direct or port injection, while diesel CLAs use high-pressure common-rail injectors — so the two types are completely different parts and cannot be swapped between fuel types. Always confirm your fuel type and engine code before requesting a quote from a breaker.

The C117 and C118 are entirely different platform generations, and despite some shared engine family names, the injector specifications, rail pressures, and connector designs often differ between them. You should treat these as non-interchangeable and confirm fitment with the breaker against your exact registration and engine code. Supplying your engine code — found on your V5 or via a VIN check — is the single most useful detail you can give the breaker.

The C117 generation ran from 2013 to 2019, with a facelift arriving in 2016 that was primarily cosmetic and interior-focused rather than a mechanical overhaul. For the same engine code, injectors are likely to be compatible across the facelift boundary, but ancillary mounting and connector changes mid-production cannot be ruled out, so you should confirm this with the breaker against your registration before ordering.

Trim level does not affect injector fitment on the CLA; what matters is the engine code, fuel type, and model year. An AMG Line and an SE on identical engine codes will use the same injector, so there is no need to seek a trim-specific part. The breaker may supply an injector from a car with different interior or exterior spec, and that is perfectly fine mechanically.

The CLA 200 and CLA 220 badges refer to different engine outputs and in most cases different engine codes, so the injectors are unlikely to be identical even within the same generation. Mechanical parts follow the engine code rather than the badge, so confirm your exact engine code with a VIN check or your V5 and supply it to the breaker rather than relying on the badged model number. Never assume injectors are interchangeable between different engine codes without breaker confirmation.

This is an important consideration that varies by engine management system and model year, and whether used injectors require coding or adaptation to your ECU is something you must confirm with the breaker or a Mercedes-trained technician against your specific registration. Some modern common-rail diesel systems in particular store injector calibration data, and fitting uncoded injectors can affect fuelling accuracy. Do not assume a used injector is a straight plug-in replacement without checking this first.
