Cheap BMW X4 Rear Cross Member

The BMW X4 has two distinct generations: the F26 (2014–2018) and the G02 (2018 onwards, facelifted 2021). The rear cross member is platform-specific, so F26 and G02 parts are not interchangeable. Always confirm the exact generation with your breaker against your registration before ordering.

These two cars sit on different generations — the 2017 is an F26 and the 2019 is a G02 — so the rear cross members are built around completely different platforms and will not swap over. You need to source a part from the matching generation. Give your breaker your full registration to make sure they pull the correct one.

The 2021 facelift updated the X4's styling but remained on the G02 platform, and in many cases structural underbody components carry across a facelift. However, mid-generation pressing changes can occur without public documentation, so you should confirm directly with the breaker that the part from a pre-facelift G02 matches your facelifted car before buying.

Trim level does not affect fitment for the rear cross member; the structure is determined by the platform and body style, not by whether the car is an xLine or M Sport. You may find cosmetic brackets or attachment points differ slightly between standard and M Performance variants, so mention your trim to the breaker, but trim alone should not change the core cross member part.

The F26 X4 shares its CLAR-predecessor platform with the F25 X3, and the G02 X4 shares underpinnings with the G01 X3, so there is a possibility of overlap, but body style differences between the two vehicles mean the rear structures may not be identical. Whether a specific cross member genuinely interchanges is something you must confirm with the breaker against both registrations rather than assume from platform sharing alone.

No — engine choice, whether petrol, diesel, or the M40i/M40d performance derivatives, does not affect the rear cross member fitment. What matters is the generation (F26 or G02) and that the part is undamaged and correctly listed to your platform. Confirm with your breaker using your registration to be certain.
