Used Mercedes-Benz GLA Crankshaft

Every petrol and diesel engine fitted to the Mercedes-Benz GLA has its own crankshaft, so yes, the part genuinely exists on this model across all variants. However, the crankshaft is specific to the engine, not the GLA badge — a 2.0-litre petrol unit will not share a crank with a 1.6-litre or any diesel. Always identify your engine code from the V5 or a VIN check before approaching a breaker, as that single detail determines which crankshaft is correct for your car.

The first-generation GLA ran from 2013 to 2019, with a facelift arriving around 2017, and within that generation the engines were broadly carried over rather than replaced at the facelift point. That said, whether a specific crankshaft from a pre-facelift engine matches a post-facelift unit of the same code depends on whether any internal engine revisions were made at that time — confirm the exact engine code with the breaker against your registration to be sure. Matching engine codes is the safest starting point.

No — the second-generation GLA (H247, launched 2020) uses a completely different engine family from the first-generation X156 (2013–2019), and the crankshafts are not interchangeable between generations even where the displacement and fuel type appear similar on paper. Treat these as entirely separate sourcing exercises and match the engine code precisely. A breaker will need your registration or engine code to pull the correct unit.

Trim level alone does not determine crankshaft fitment — what matters is the engine code, which can vary independently of trim. The AMG 45 variants use a distinct high-output 2.0-litre engine with its own crankshaft specification, whereas Sport and AMG Line badges can be fitted across several different engine options, so two AMG Line cars may need different crankshafts depending on which engine is under the bonnet. Always lead with the engine code, not the trim name, when requesting quotes from a breaker.

Yes, fuel type is one of the most fundamental fitment factors for a crankshaft, as petrol and diesel engines have entirely different internal architectures and the crankshafts are never interchangeable between them. Beyond fuel type, displacement and engine code further narrow the field — a 2.2-litre diesel crank will not fit a 2.0-litre diesel, for example. Provide your engine code to the breaker rather than just stating 'diesel' or 'petrol' to avoid any ambiguity.

Mercedes-Benz frequently fits the same engine family across multiple models, so if the engine code genuinely matches between, say, an A-Class (W176 or W177) and a GLA (X156 or H247), the crankshaft internals may well be identical. However, confirm this directly with the breaker against both registrations, as ancillary or mounting differences can sometimes exist even within shared engine families. A reputable breaker will cross-reference the codes before selling the part.
