Used BMW 3 Series Rear Cross Member

No — the E46 (1998–2005) and E90 (2005–2013) are entirely different platforms, and the rear subframe and cross member geometry changed completely between them, so parts are not interchangeable. Always confirm the exact part against your registration with the breaker.

Yes, body style is the key factor here — the saloon (E90), touring/estate (E91), coupe (E92), and convertible (E93) all share the same E90-generation platform but have different rear structures, and the cross member is not shared across body styles. When contacting a breaker, make sure you specify your exact body style as well as the generation.

The E90 generation ran from 2005 to 2013 with a facelift in 2008, and while the platform remained the same throughout, whether the cross member pressing changed at that facelift point is something you should confirm with the breaker against your registration rather than assume either way.

Trim level does not affect fitment for this part — SE, Sport, and M Sport are all fitted to the same bodyshell, so the rear cross member is the same piece regardless of trim. The only differences between those trims are cosmetic or mechanical (wheels, suspension tuning, body kit), none of which affect the cross member itself.

The E46 saloon and E46 touring (estate) are different body styles on the same platform, and the rear structures differ between them, so a touring cross member should not be assumed to fit a saloon. Confirm the donor body style matches yours exactly when speaking to the breaker.

The F30 (saloon, 2012–2018, facelift 2015) and F31 (touring/estate, 2012–2019) share the same F30-generation platform, but because the touring has a different rear body structure the cross member is likely to differ — confirm against your exact body style and registration with the breaker before ordering.
