Cheap BMW 1 Series Gearbox

Both years fall within the F20/F21 generation (2011–2019, facelift 2015), so you are working within the same platform, but the engine code is the critical factor — a gearbox matched to the same engine code is far more likely to suit than simply sharing a model year. Name the exact engine code from your V5 or a VIN check when you contact a breaker, as ancillary and mounting changes can occur mid-production even within a generation. Never assume fitment on year alone; always confirm with the breaker against your registration.

The E87 is the first-generation 1 Series (2004–2011) and the F20 is the second generation (2011–2019), and these are entirely different platforms with different engine families, so a straight swap is very unlikely. The engine codes changed substantially between generations, and the gearbox mounts, bell-housing patterns, and electronic integration differ. Always confirm with the breaker against your registration rather than attempting to cross this generational boundary.

No, the trim level does not determine gearbox fitment on the BMW 1 Series — Sport, M Sport, and SE badges describe interior, cosmetic, and suspension specifications, not the drivetrain. What matters is the engine code, fuel type (petrol or diesel), and whether the car has a manual or automatic gearbox. Supply your engine code and gearbox type to the breaker and the trim name can be safely ignored for this purpose.

The F20 facelift arrived in 2015, and while the overall platform continued, there were engine revisions at that point — notably updates to certain four-cylinder units — which can affect gearbox compatibility. The engine code from your V5 is the most reliable guide here, as it reflects the actual specification rather than the facelift date. Confirm with the breaker against your registration whether the specific unit crosses the 2015 facelift boundary cleanly.

The 2008 118d sits in the E87/E81/E88 generation (2004–2011) and uses a specific diesel engine code — checking your V5 for that code is essential, as different diesel variants in that generation used different gearbox configurations. Fuel type and engine code must both match; a petrol-derived gearbox from the same year will not suit a diesel application. Provide your engine code and registration to the breaker so they can match the correct unit.

Body style does not affect gearbox fitment — the gearbox follows the engine and drivetrain specification, not the shape of the car. As long as the engine code, fuel type, and gearbox type (manual or automatic) match your vehicle, a unit from a different body style in the same generation is mechanically the same candidate. Confirm with the breaker against your registration, particularly regarding any ancillary fittings or sensor configurations that may vary.
