Used BMW X7 Cylinder Head

The BMW X7 (G07) launched in 2019 and received a significant facelift in 2022, so a 2020 head comes from the pre-facelift generation and a 2023 head from the facelifted generation — crossing that boundary means you should not assume interchangeability even if the engine code looks the same on paper. The engine code printed on your V5 or revealed by a VIN check is the single most important detail to match, and you should confirm with the breaker whether the specific casting crosses the 2022 facelift boundary cleanly for your registration.

Yes — for a mechanical part like a cylinder head, the engine code is the definitive reference, not the model year or badge. Two X7s of different years can share the same head if they share the same engine code, while two X7s of the same year can require completely different heads if they carry different engines. Find your engine code on your V5, inside the engine bay, or via a VIN check, and quote it to the breaker before agreeing anything.

Absolutely — the xDrive30d is a diesel inline-six and the xDrive40i is a petrol inline-six, so the cylinder heads are entirely different and will not interchange. The trim or xDrive badge itself does not affect fitment, but the fuel type and specific engine code behind that badge does. Always confirm your exact engine code with the breaker rather than relying on the model name alone.

Trim level — whether your X7 is M Sport, xLine, or Pure Excellence — has no bearing on which cylinder head the car uses; fitment follows the engine code, not the trim badge. If both cars share the same engine code, the head from an M Sport donor is mechanically the same part, so you should not pay extra or less based on trim alone. Confirm the engine code match with the breaker and note that any cosmetic ancillaries on the donor car may differ, but the head itself is what matters.

The 2022 facelift is a known production boundary for the G07 X7, and while some engine codes carried across it, ancillary and mounting changes mid-production mean you cannot assume a pre-facelift head drops straight onto a post-facelift block without modification. Name your exact engine code to the breaker and ask them to confirm compatibility against your specific registration — that check is the only reliable way to know whether the crossing works for your car.

Gearbox type does not directly determine the cylinder head specification, but it is worth mentioning to the breaker as part of your overall engine build description, since some engine variants were only ever paired with certain transmissions in the X7. The engine code remains the primary fitment reference, so lead with that when contacting a breaker, and let them cross-reference the gearbox as a secondary check.
