Second Hand BMW Z4 Flywheel

Yes, but only on manual gearbox variants — the Z4 was available with both manual and automatic transmissions, and a traditional flywheel (or dual-mass flywheel) only exists in the manual gearbox drivetrain. Automatic versions use a torque converter with a flexplate (driveplate) instead, which is a completely different part. If your Z4 is an automatic, you need to search for a flexplate rather than a flywheel.

Almost certainly not — the E85 and E89 are different generations with substantially different engine families, and the flywheel follows the engine code rather than the model badge. Even where engine displacements sound similar across the two generations, the mounting dimensions, bolt patterns, and clutch mating faces frequently differ. Confirm your engine code from your V5 or a VIN check and supply it to the breaker before ordering.

The engine code is the most important detail — a flywheel is matched to the engine's crankshaft flange and the clutch it drives, so two Z4s from different years with the same engine code are far more likely to interchange than two same-year cars with different engines. That said, there can be running production changes mid-year that affect ancillary details, so always give the breaker your full registration so they can cross-reference against your specific build. Never assume a match on year alone.

Trim and badge names like sDrive23i or sDrive30i reflect different engines entirely, so yes, they will have different flywheels — but it's the engine code driving that difference, not the trim level itself. Two cars wearing the same badge but built in different model years could share a flywheel if the engine code is unchanged, while two different-badged cars with the same underlying engine code might use the same part. Always lead with the engine code when speaking to a breaker.

The 3.0si and the earlier 3.0 used different engine variants within the E85 generation, so the flywheels are not necessarily the same part even though the displacement sounds identical. Check the engine code on your V5 or via a VIN check and compare it directly with the donor vehicle's engine code before proceeding. Confirm compatibility with the breaker against both registrations to be certain.

If the engine codes genuinely match and both cars are manual gearbox, there is a reasonable chance of compatibility since BMW reused engine families across multiple models — but this is something to route through the breaker rather than assume. Clutch housing dimensions and any ancillary bracket differences between platforms can occasionally affect fitment even with the same engine code. Give the breaker both registrations and let them verify against their parts data before you buy.
