Mercedes-Benz X-Class Flywheel Replacement Parts

It depends on the gearbox fitted to your X-Class. X-Class models with a manual gearbox use a conventional solid flywheel (or dual-mass flywheel depending on variant), whereas X-Class models fitted with the 7G-Tronic automatic gearbox use a flexplate (also called a driveplate) instead of a flywheel — these are not interchangeable. Check your gearbox type before searching, and if you have an automatic X-Class, a flexplate is almost certainly the part you actually need.

Only X-Class models paired with a manual gearbox will have a flywheel — the 6-speed manual versions of the X 220 d and X 250 d diesel engines are the most common candidates in the UK market. The X 350 d and any automatic-gearbox variants use a flexplate rather than a flywheel, so searching for a flywheel on those vehicles will lead you to the wrong part. Confirm your gearbox type from your V5 or a VIN check before ordering.

The X-Class had a very short single-generation production run from 2017 to 2020 with no significant facelift, so year-to-year variation is less of a concern than on longer-lived models. What matters far more is the engine code — the X 220 d and X 250 d share a Nissan-derived engine family but have different displacement and outputs, so their flywheels are not necessarily interchangeable even within the same year. Always match on engine code first, then confirm with the breaker against your registration.

No — trim level (Progressive, Stylish, or Power) has no effect on flywheel fitment whatsoever, as this is a purely mechanical component determined by engine and gearbox, not by trim specification. A flywheel from a Progressive-spec X 250 d manual is mechanically the same part as one from a Power-spec X 250 d manual. You may find cosmetic or interior differences between donor vehicles at the breaker, but these are irrelevant when sourcing a flywheel.

The X-Class, Nissan Navara (D23) and Renault Alaskan share platform and engine architecture, and in some cases flywheel components may be interchangeable, but this is not guaranteed due to potential differences in ancillary mounting or specification between the badge-engineered variants. The engine code is the key starting point — if the codes match exactly, fitment is more likely, but you should confirm directly with the breaker against your registration before purchasing. This cross-platform route can sometimes open up more stock options, which is worth exploring with a knowledgeable dismantler.

Used dual-mass flywheels can be a cost-effective option but carry more risk than solid flywheels, as the internal spring mechanism wears over time and a high-mileage unit may be near the end of its serviceable life even if it looks intact externally. Ask the breaker for the mileage of the donor vehicle and whether there were any symptoms of DMF wear — such as rattling at idle or judder on take-up — before it was dismantled. Always match the engine code from your V5 or VIN check to the donor vehicle, and never guarantee fitment based on model name alone.
