Used BMW M4 Dual Mass Flywheel

The BMW M4 is only available with a petrol engine and has been offered with both a manual gearbox and an automatic (dual-clutch or torque-converter depending on generation) — dual mass flywheels are found on manual-gearbox variants, as automatics use a torque converter instead. The F82 M4 (2014–2020) with the S55 engine and six-speed manual does use a dual mass flywheel, and the G82 M4 (2021–present) with the S58 engine and six-speed manual also uses one. If your M4 has an automatic gearbox, a dual mass flywheel is not the part you need — confirm your gearbox type before ordering.

The F82 and G82 M4 are separate generations using different engines — the S55 in the F82 and the S58 in the G82 — and the flywheel is matched to the engine and gearbox bell-housing, so these are not interchangeable. You should quote your engine code to the breaker and confirm against your registration to make sure you're being supplied the correct unit for your generation.

The Competition trim on both the F82 and G82 M4 brings suspension, power, and software differences, but the engine code and gearbox type are what determine flywheel fitment, not the Competition badge itself. Where the engine code and gearbox type match between a standard and Competition car of the same generation, the flywheel should be the same part — but confirm the engine code with the breaker against your registration before buying.

The M3 saloon and M4 coupe within each generation do share the same engine — S55 in the F80 M3 and F82 M4, and S58 in the G80 M3 and G82 M4 — so a flywheel from the equivalent-generation M3 manual is widely considered to be the same part. That said, always confirm the engine code and gearbox code with the breaker against both registrations before proceeding, as ancillary specifications can vary.

Within a single generation — for example anywhere in the F82 M4's 2014–2020 production run — the core flywheel is generally consistent because the S55 engine and six-speed manual combination did not change fundamentally. However, mounting or ancillary details can sometimes change mid-production without a formal facelift, so confirm the specific part number with the breaker against your exact registration to rule out any subtle differences.

No — dual mass flywheels are only used in conjunction with a manual clutch and pressure plate assembly; automatic and dual-clutch gearbox variants use a torque converter to perform the same function of dampening drivetrain vibration. If your M4 is fitted with the seven-speed DCT or the eight-speed automatic found in some G82 M4 variants, the part you may be looking for is a torque converter rather than a flywheel — confirm this with the breaker.
