Mercedes-Benz CLA Crankshaft Replacement Parts

The Mercedes-Benz CLA (C117) ran from 2013 to 2019, with a facelift arriving in 2016, so a 2014 and a 2017 car sit either side of that facelift boundary. Crankshaft fitment is driven by engine code above everything else, so if both cars share the same engine code — for example, both running the M270 2.0 petrol or OM651 2.2 diesel — the crank itself is very likely the same casting. However, ancillary components and sensor pick-up rings can change across a facelift, so confirm against your specific registration with the breaker before buying.

The CLA 200 and CLA 220 are badges, not different engines — both petrol versions of these use variants of the M270 four-cylinder family, but the state of tune and exact specification can differ, meaning the crankshaft may or may not be identical. The only reliable way to confirm interchange is to supply both engine codes (found on the V5 or via a VIN check) to the breaker, who can match them directly. Do not assume the badge alone determines fitment.

Trim level has no bearing whatsoever on crankshaft fitment — AMG Line, Sport, and other trim designations on the CLA are cosmetic and equipment packages, not mechanical specifications. What matters is the engine code, fuel type, and gearbox type, all of which are the same across trims fitted with the same engine. When you contact a breaker, give them your engine code rather than your trim name and you will get a much more useful answer.

Yes, every internal combustion engine variant of the Mercedes-Benz CLA has a crankshaft — it is a fundamental rotating component present in all petrol and diesel engines, including the M270 petrol and OM651 diesel units used across the C117 and X117 ranges. Unlike parts such as a propshaft (which only exists on four-wheel-drive layouts), a crankshaft is universal to all engine-powered variants of this model. If you are looking at a fully electric vehicle you would not need one, but the CLA did not have a pure-electric variant in the C117 generation.

The CLA Shooting Brake (X117) used the same engine family as the C117 saloon, so if the engine codes match, the crankshaft from a saloon donor is the one to look at. Body style makes no difference to crankshaft fitment whatsoever — the part lives inside the engine and is completely unaffected by whether the car is a saloon or an estate. Confirm the engine codes match with the breaker against both registrations before proceeding.

No — diesel and petrol engines are entirely different units, and their crankshafts are not interchangeable. The CLA diesel (typically the OM651 2.2-litre) and the CLA petrol (typically the M270 1.6 or 2.0-litre) have different bore spacing, stroke, and counterbalance specifications. Always source a crankshaft that matches your exact engine code, and supply that code to the breaker at the point of enquiry.
