Cheap BMW X4 Flywheel

It depends entirely on the gearbox type: manual-gearbox variants of the X4 use a traditional solid flywheel, while the far more common automatic (ZF eight-speed) variants use a flexplate (also called a flex disc or drive plate) rather than a conventional flywheel. The vast majority of X4s sold in the UK came with the automatic gearbox, so if yours is an auto, a flywheel is not the part you need — you should be searching for a flexplate or torque converter drive plate instead. If you are unsure which you have, check your V5 or run a VIN check before ordering.

Both years fall within the first-generation X4 (F26), which ran from 2014 to 2018, so they share the same basic platform. That said, flywheel fitment is driven primarily by engine code and gearbox type, not the model year alone, so you should match the engine code from your V5 rather than relying on year alone. Confirm the specific part number with the breaker against your registration before purchasing.

The F26 and G02 are entirely different generations on different platforms, and their engines, though sometimes sharing a family name, carry different engine codes — so a flywheel from an F26 will not simply cross over to a G02. Always match by engine code first, and check with the breaker against your exact registration, as mounting and ancillary details can vary even between engines with similar displacements across the generation change.

Trim level — whether SE, xLine, M Sport, or M40i badging — has no bearing on flywheel fitment whatsoever, as the flywheel is determined by engine code and gearbox type, not the specification package. What matters is whether your engine code matches the donor vehicle's engine code, and whether both cars have the same gearbox type. You can safely ignore trim differences when searching, but do confirm the engine code with the breaker.

The xDrive20d badging covers several different engine codes across the F26 and G02 generations — for example, the N47 and later B47 diesel units both appeared under that badge at different points, and they are not interchangeable. The engine code is stamped on the engine itself and also appears on your V5 or via a VIN check, and that code is the single most important detail to give a breaker when sourcing a flywheel. Never rely on the badge or displacement alone — always quote the full engine code.

On an automatic X4 the part that connects the engine to the torque converter is a flexplate (sometimes called a flex disc or drive plate), not a solid flywheel — a solid flywheel is a manual-gearbox component. If a breaker has quoted you a flywheel for an automatic X4, it is worth clarifying with them whether they mean a flexplate, as the two parts are quite different in construction and function. Double-check by confirming your gearbox type and engine code with the breaker before any money changes hands.
