BMW 2 Series Gearbox Replacement Parts

The BMW 2 Series (F22/F23/F45/F46) ran from 2014 through to 2021, so both years sit within the same generation — however, the engine code is the critical factor, not the year alone. A gearbox from a 2014 car can potentially suit a 2017 car if the engine codes match, but ancillary and mounting changes mid-production mean you should confirm compatibility with the breaker against your exact registration before buying. Never assume a same-generation match is automatic.

Many F20/F21 1 Series and F22/F23 2 Series models share the same engine codes and gearbox units, so there is genuine crossover — but fitment depends entirely on matching the engine code, not the badge or body style. Supply your engine code (found on your V5C or via a VIN check) to the breaker so they can verify the specific unit is correct. Do not assume all 1 Series gearboxes fit all 2 Series without that check.

Trim level — whether Sport, M Sport, or SE — does not affect gearbox fitment; what matters is the engine code, fuel type, and whether the car has a manual or automatic transmission. An M Sport and an SE with the same engine code and gearbox type use mechanically identical units, so trim is irrelevant here. Bear in mind the breaker's car may have different interior or exterior cosmetic features, but that has no bearing on whether the gearbox itself will suit your vehicle.

The 218d typically uses a four-cylinder diesel engine, but BMW used more than one engine code in this variant across the production run and in different markets, so quoting a single code as fact here could mislead you. The safest step is to check your V5C or run a VIN check to confirm your exact engine code, then give that code directly to the breaker — engine code matching is the single most reliable way to source the correct gearbox.

No — petrol and diesel gearboxes are not interchangeable even within the same model year, as the units are engineered around the engine's torque output, bolt pattern, and other characteristics specific to that engine. Always match gearbox type (manual or automatic), fuel type, and engine code together when sourcing a used unit. Confirm all three details with the breaker against your registration to avoid an incompatible purchase.

For the gearbox itself, body style does not affect fitment — the mechanical unit is determined by engine code, fuel type, and transmission type rather than whether the car is a coupe or convertible. That said, confirm with the breaker against your registration, as ancillary components or mounting brackets associated with the gearbox can vary mid-production in ways that are not always documented publicly. Getting the breaker to cross-reference your exact registration is the safest approach.
