Mercedes-Benz GLB Crankshaft Replacement Parts

Yes, every variant of the GLB has a crankshaft — it is a core internal engine component present in all petrol and diesel versions of the GLB X247, which launched in the UK in 2019. The crankshaft design varies depending on which engine is fitted, so the engine code is the critical detail when sourcing one from a breaker. Make sure you have your engine code to hand before requesting quotes, as the same GLB badge can cover meaningfully different engines.

The GLB X247 is the only generation produced so far, running from 2019 to the present, with a facelift arriving in 2023 that brought some updates but did not introduce entirely new engine families. Whether a pre-facelift (2019–2022) crankshaft crosses over to a post-facelift (2023-on) example of the same engine code is something you should confirm with the breaker against your registration, as ancillary and internal changes can occur mid-production. Providing your full engine code — found on your V5 or via a VIN check — gives the breaker the best chance of confirming compatibility accurately.

Yes, this matters significantly — the 200d and 220d both use diesel engines but they are different engine variants with different internal specifications, and the crankshaft is not interchangeable between them. The engine code, rather than the badge number, is the definitive guide here, so check your V5 or run a VIN check to confirm the exact code before approaching a breaker. Never assume a crankshaft will fit based on the badge alone.

Trim level makes no difference to crankshaft fitment — Sport, AMG Line, AMG Line Premium, and any other trim grade are purely cosmetic and equipment distinctions that have no bearing on the engine internals. What matters is the engine code, fuel type, and whether the car is automatic or manual (though virtually all UK GLBs are automatic). Confirm your engine code with the breaker and the trim badge can be ignored entirely for this part.

The 4MATIC all-wheel-drive system is entirely separate from the engine's internal components, so it has no bearing on crankshaft selection. The crankshaft in a GLB 250 4MATIC is determined solely by the engine code, which on the 250 is a petrol unit — confirm the exact code from your V5 or VIN check before requesting quotes from a breaker. A rear-wheel-drive or front-wheel-drive GLB running the same engine code would use the same crankshaft.

Mercedes-Benz shares engine families across several models in the compact range, so a crankshaft from an A-Class, CLA, or GLA running an identical engine code could potentially be compatible with a GLB — the engine itself does not care which bodyshell it came from. However, you must confirm this cross-model fitment with the breaker against your specific registration and engine code, as subtle mid-run revisions can affect parts even within the same engine family. Providing both the donor vehicle's and your own engine codes to the breaker is the safest approach.
