Used BMW 1 Series Rear Cross Member

The E81/E87 generation ran from 2004 to 2013, and within that generation the rear cross member is platform-specific, so body style is the key variable — the 3-door hatch (E81) and 5-door hatch (E87) have different rear structures and their cross members are not interchangeable. Engine and trim level make no difference to fitment at all. Always confirm the exact body style and door count with the breaker against your registration before buying.

No — the E87 (2004–2013) and the F20 (2011–2019) are entirely different generations on different platforms, and the rear cross member is not transferable between them. The two generations share no meaningful structural compatibility at the rear. Stick to sourcing from the correct generation and confirm with the breaker using your registration.

The F20 second-generation 1 Series ran from 2011 to 2019, with a facelift in 2015, and both are the same underlying platform. Whether the rear cross member itself changed across that 2015 facelift boundary is not something we'd state as fact — confirm directly with the breaker by quoting both registrations so they can check their part against yours.

Trim level — whether SE, Sport, M Sport, or M140i — makes no difference to rear cross member fitment on the BMW 1 Series; this is a structural chassis component, not a trim-dependent panel. You may find cosmetic differences around the rear bumper area depending on trim, but the cross member itself is the same across trim grades within the same generation and body style. Confirm body style and door count with your breaker, and that's all you need to worry about on fitment.

No — the 3-door and 5-door variants of the BMW 1 Series have different rear body structures, and the rear cross member is not shared between them. Body style is the single most important fitment factor for this part, even within the same generation. Always tell the breaker your exact door count alongside your registration to make sure you're quoted the right part.

Both a 2010 and a 2012 1 Series fall within the E87/E81 generation (2004–2013), so they share the same platform. Provided the body style and door count match — 3-door to 3-door or 5-door to 5-door — fitment is very likely, but confirm with the breaker against both registrations before purchasing as mid-generation pressing changes can occasionally occur.
