Cheap BMW 8 Series Dual Mass Flywheel

Yes, but only on diesel and manual or automatic transmission petrol variants — the 8 Series (G15 coupe, G14 convertible, G16 gran coupe, all produced from 2018 onwards) uses dual mass flywheels on its diesel engines such as those found in the 840d, and on certain petrol manual-gearbox applications where fitted; the high-performance M850i and M8 with their torque-converter automatics may use a different arrangement, so confirm with the breaker against your exact registration before ordering.

No — the original E31 8 Series (1989–1999) and the current G-series 8 Series (2018–present) are entirely separate generations with completely different engines, bellhousing designs, and drivetrain layouts, so parts are not interchangeable between them at all. The dual mass flywheel is matched to the engine code and gearbox bell housing, not the model name, so even a superficially similar part will not cross between generations. Always supply your engine code — found on your V5 or via a VIN check — to the breaker so they can match the correct unit.

No — trim levels like Sport, M Sport, and M Sport Pro on the G-series 8 Series are cosmetic and equipment packages that do not affect the dual mass flywheel fitment at all. The flywheel is determined entirely by the engine code and gearbox type, so an 840d in any trim will use the same flywheel as another 840d with the same engine code and gearbox. You may find cosmetic differences between cars at the breaker's yard but these are irrelevant to the mechanical parts you need.

Potentially yes, as both fall within the G-series generation (2018–present) and if the engine codes and gearbox types match, the flywheel is likely the same unit, but confirm this with the breaker against your registration before purchasing. Minor ancillary or mounting changes can occur mid-production even within a generation without a formal facelift, so the breaker should verify part numbers against both vehicles. The engine code on your V5 is the single most useful detail you can supply to get a confident answer.

Where the engine code and gearbox type are identical, the dual mass flywheel is the same part regardless of body style — the G15 coupe, G14 convertible, and G16 gran coupe all share the same engine family within the G-series range launched from 2018. Body style does not influence flywheel fitment, so a matching engine code is what matters. Supply your engine code and registration to the breaker and they will confirm the correct unit.

The engine code is the single most important detail — it is printed on your V5 registration document or can be obtained via a VIN check — and you should also confirm your gearbox type (automatic or manual) and fuel type (petrol or diesel) when contacting the breaker. Year of manufacture helps narrow things down within the G-series generation (2018–present) but the engine code overrides year alone. Never assume a part fits based solely on model name or badge, as the 8 Series range includes multiple engine variants with different flywheel specifications.
