Engine Finders matches UK buyers searching for 'M254.920 engine for sale', 'reconditioned M254.920 price' or 'Mercedes-Benz GLC 300 (X254) engine replacement cost' with vetted suppliers who carry the correct unit for your exact car — supply-only or supply-and-fit, used or professionally reconditioned, whichever suits your budget and timeline.

Mercedes-Benz GLC 300 (X254) Replacement Engines

A replacement M254.920 engine for the Mercedes-Benz GLC 300 (X254) is a significant purchase, so getting the exact code right matters more than the badge on the boot. The M254 family brings 48-volt mild-hybrid assistance to the current GLC range, shared with several other current Mercedes-Benz models including the CLE and C-Class at different tunes. Whether you call it a rebuilt engine, a remanufactured unit, or a reconditioned replacement, the work involved is broadly the same: a full strip-down, inspection against factory tolerances, replacement of wear parts, and bench testing before it's fitted or dispatched to you.

GLC 300 (X254) Models & Engine Codes

The Mercedes-Benz GLC 300 (X254) uses the M254.920 (2.0-litre four-cylinder, Petrol turbo, 48-volt mild hybrid), fitted to GLC 300 (X254) across 2022 to present. Don't assume the X254's M254 is interchangeable with the previous X253's M274 despite the shared GLC 300 badge — the two are completely different engine families. Before ordering any used, reconditioned or rebuilt unit, confirm this code from your V5C or the number stamped on the engine block itself — the same badge can sometimes cover more than one engine across a model's production run, and getting this step right avoids an expensive mismatch.

Buy Used and Second-Hand Mercedes-Benz GLC 300 (X254) Engines

Used M254.920 engines do come up for sale in the UK, generally sourced from donor or written-off Mercedes-Benz GLC 300 (X254) cars. A used engine can look like the cheaper option at first glance, but once you've accounted for inspection, gaskets, ancillaries and the lack of a meaningful warranty, a professionally reconditioned or remanufactured M254.920 unit is often the better value over the life of the car.

Mercedes-Benz GLC 300 (X254) M254.920 Engine Problems & What to Check Before Buying

We have not found catalogue-grade documented issue reports specific to this application that we are prepared to publish here; this is also a relatively recent model generation. We note this as general background for anyone researching a M254.920 replacement, not as a confirmed finding for any specific car — ask your supplier what inspection was carried out on the unit you're being quoted, and whether known wear points for this engine family were addressed during the rebuild.

What's Included in a Reconditioned Mercedes-Benz GLC 300 (X254) M254.920 Engine

A genuine reconditioned or remanufactured M254.920 unit should include a full strip, clean and inspection against factory tolerances, replacement of gaskets, seals and wear items, and a bench test before it leaves the workshop. What's not always included — ancillaries like the turbo, injectors or auxiliary belt components, and whether the price is supply-only or supply-and-fit — varies by supplier, so ask for this in writing alongside your M254.920 engine quote rather than assuming it's covered.
