Mercedes-Benz GLA Flywheel Replacement Parts

It depends entirely on the gearbox type fitted to your specific GLA. Manual-gearbox GLA variants use a traditional solid flywheel, while automatic-gearbox variants (which cover the majority of UK GLAs) use a dual-mass flywheel (DMF); purely automatic variants with a torque converter do not use a conventional flywheel in the same sense. Check your V5 or run a VIN check to confirm your exact gearbox type before searching, and let the breaker know whether you have a manual or automatic.

The GLA ran as the X156 first generation from 2013 to 2019, with the H247 second generation launching in 2020, and these are fundamentally different platforms. A flywheel from an X156 will not cross to an H247 — engine mountings, bellhousing dimensions and engine codes differ between generations. Always source within the correct generation and match the engine code precisely.

The X156 received a facelift in 2017 but remained the same underlying generation, so the facelift itself is unlikely to have changed the flywheel specification for a given engine code. The engine code is the critical detail here — if both cars share the same engine code and gearbox type, fitment is likely, but mid-production ancillary changes are possible so you should confirm directly with the breaker against your exact registration before buying.

For standard variants, trim level — SE, Sport, AMG Line — makes no difference to the flywheel whatsoever; fitment follows the engine code and gearbox type, not the badge on the tailgate. The AMG 45 variants (using the M133 or M139 engine codes) are a different matter, as they carry a distinct high-performance engine and you must source a flywheel matched to that specific engine code. Tell the breaker your engine code and gearbox type and ignore the trim name for this purpose.

The single most useful piece of information is your engine code, which you can find on your V5 logbook or via a VIN check — it will be something like M270, M274, OM607 or OM651 depending on your variant. You should also confirm your fuel type (petrol or diesel) and gearbox type (manual or automatic), since a manual-transmission GLA uses a solid or dual-mass flywheel while an automatic uses a different arrangement entirely. Your registration year and generation (X156 2013–2019, or H247 2020 onwards) will help the breaker locate the right donor vehicle quickly.

No — diesel and petrol engines use different flywheel specifications, and the parts are not interchangeable even if the gearbox type is the same. Diesel engines typically produce higher torque at lower revs and the flywheel is engineered accordingly, so always match the part to your exact fuel type and engine code. Supply the breaker with both your engine code and fuel type to avoid any mismatch.
