BMW X7 Dual Mass Flywheel Replacement Parts

Yes, but only on diesel and manual-or-automatic petrol variants that use a traditional torque-converter automatic gearbox — the X7 G07 (launched 2019) is available with turbocharged six-cylinder and eight-cylinder petrol and diesel engines, and the diesel units in particular are fitted with a dual mass flywheel (DMF) as standard. However, X7 models paired with a pure electric drivetrain or a plug-in hybrid system use different driveline components and do not use a conventional DMF in the same way. Check your V5 or run a VIN check to confirm your exact engine code before searching, as that determines whether a DMF is part of your drivetrain.

The BMW X7 is all one generation — the G07 — spanning 2019 to the present, with a mid-cycle facelift arriving in 2022. The engine codes (for example B57 for the 3.0 diesel or N63 for the 4.4 V8 petrol) are the critical matching point, and if the engine code is the same across that 2019–2022 boundary the flywheel itself is generally considered the same family of part. However, whether ancillary or mounting details changed at the 2022 facelift is something you should confirm with the breaker against your exact registration, as mid-production revisions are not always publicly documented.

Trim level and badge do not determine flywheel fitment — the engine code does. An xDrive40d uses the B57 diesel engine and its associated DMF, while an M50i or M60i uses a petrol V8 (N63 or S68 respectively) with its own flywheel specification; two cars wearing the same M50i badge but built at different points in production will share a flywheel because the engine code is identical. Confirm the engine code from your V5 or a VIN check and supply it to the breaker — trim name alone is not enough.

Yes, fuel type matters significantly because the diesel (B57, six-cylinder) and petrol (N63 or S68, V8) engines have completely different flywheel assemblies that are not interchangeable. Always confirm your engine code — not just 'petrol' or 'diesel' — and pass that to the breaker so they can match the correct part. Fitting the wrong flywheel family risks serious driveline damage, so treat the engine code as non-negotiable when sourcing.

Because the flywheel follows the engine rather than the vehicle, a B57-equipped 5 Series (G30) or 7 Series (G11/G12) flywheel is potentially in the same family as the one in your X7 G07. In practice this is a common way breakers source matching parts, and the engine code is your key reference point. That said, whether mounting or ancillary details vary between vehicle applications is something you should verify with the breaker against both registrations before purchasing, as cross-model fitment carries additional risk.

The dual mass flywheel itself is a mechanical component and does not hold electronic calibration data, so in most cases it does not require coding in the way an ECU or instrument cluster would. However, whether any associated sensors, adaptations, or gearbox control units need resetting or relearning after fitment is something you should confirm with the breaker and your fitting garage, as this can vary and is not something that can be stated as fact for every vehicle.
