Mercedes-Benz CLA Camshaft Replacement Parts

Yes, every CLA has at least one camshaft — all CLA engines, whether petrol or diesel, use camshafts to operate the valves, and most variants use a twin-cam (DOHC) setup with separate intake and exhaust camshafts per cylinder bank. The part genuinely exists across the full CLA range, so sourcing a used one from a breaker is straightforward provided you match it correctly to your engine code.

The engine code is the single most important piece of information — it tells the breaker exactly which camshaft profile, timing system, and phaser arrangement your engine uses, far more precisely than the year or badge alone. You can find the engine code on your V5C or by running a VIN check, and it will typically be a combination like M270, M274, OM651, or similar depending on whether your CLA is petrol or diesel. Giving a breaker your full engine code will get you an accurate quote and avoid costly mismatches.

The C117 ran from 2013 to 2019 and the C118 launched in 2019, and while some engine families carried across the generation change, the camshafts are not guaranteed to be interchangeable because ancillary dimensions, phaser designs, and timing system specifications can differ even within the same engine family. You should confirm compatibility against your specific registration with the breaker rather than assuming a C117 donor part will drop straight into a C118. Sharing your engine code with the breaker is the fastest way to resolve this.

Within the C117 generation (2013–2019), fitment is primarily governed by engine code rather than model year, but Mercedes did introduce mid-cycle updates — including a facelift around 2016 — that could coincide with running changes to ancillary components or timing systems. If the engine code on the donor car matches yours exactly, fitment is far more likely, but you should still confirm with the breaker that no mid-production specification changes affect your specific year. Never rely on year alone without verifying the engine code matches.

Absolutely — petrol and diesel camshafts are completely different parts, designed around entirely different combustion cycles, valve timing profiles, and in many cases different phaser mechanisms, so they are not interchangeable under any circumstances. Petrol CLA variants typically use Mercedes' M270 or M274 four-cylinder engines, while diesel CLAs used the OM651 family, each with their own distinct camshaft specifications. Always confirm both fuel type and engine code with your breaker.

For standard SE and AMG Line trims sharing the same engine code, the trim level makes no difference to camshaft fitment — the camshaft follows the engine, not the badge or trim pack. However, full AMG variants such as the CLA 45 AMG use a different, high-performance engine (such as the M133 or M139 depending on generation) with its own specific camshaft specification, so these are not interchangeable with standard-trim units. Always confirm your engine code rather than relying on the trim name alone.
