Used BMW M5 Dual Mass Flywheel

The BMW M5 has always used a high-revving petrol engine paired with either a manual gearbox or a dual-clutch/automated transmission, and in all generations the M5 uses a single-mass flywheel rather than a dual mass flywheel (DMF). DMFs are typically found on diesel engines or lower-revving petrol units where they manage low-frequency torque pulses, but the M5's high-rpm, high-output petrol engines are not engineered around a DMF. If you are hearing rattling, juddering, or drivetrain noise on your M5, the part you may actually be looking for is the single-mass flywheel, the clutch assembly, or the flex disc (guibo) in the driveline.

Yes — BMWs that commonly use a dual mass flywheel include diesel-engined models such as the 5 Series 520d, 525d, and 530d, where DMFs are standard fitment to handle the higher torque and lower engine speeds characteristic of diesel drivetrains. Petrol-engined models with heavy low-end torque, such as some turbocharged six-cylinder variants, can also use them. If you own a 5 Series with a diesel engine rather than an M5, a DMF is very likely to be the correct part — supply your engine code (found on your V5C or via a VIN check) to a breaker to confirm the right unit.

On manual-gearbox M5s (E28, E34, E39, E60, F10 generations), the parts most likely responsible for judder or vibration are the single-mass flywheel, the clutch plate and pressure plate, or the release bearing. On later M5s with the DCT or SMG automated gearbox, the fault is more likely within the transmission's internal clutch packs or the mechatronics unit rather than a flywheel at all. Describe your symptoms clearly to a breaker and provide your registration or engine code, as they will be able to identify the correct part for your specific gearbox type.

The F10 M5 uses the S63 twin-turbocharged 4.4-litre V8 engine, which is mated to either a seven-speed DCT or the older SMG-derived automated gearbox — neither setup uses a dual mass flywheel. The S63 is a high-revving performance unit and the drivetrain is engineered without a DMF, so this part simply does not exist in the F10 M5's drivetrain. If you have an F10 M5 with drivetrain concerns, speak to a breaker about the clutch pack, flywheel (single mass), or transmission components specific to the DCT or SMG unit fitted to your car.

No — trim level makes no difference here because the absence of a dual mass flywheel is determined by the engine and drivetrain, not the specification level. The Competition, CS, and standard M5 variants across generations all share the same fundamental engine and transmission architecture, and none of them use a DMF. Trim level affects things like suspension tuning, exhaust note, and interior specification, but it does not change the flywheel type, so there is no M5 trim variant to seek out that would have one fitted.
