BMW X6 Gearbox Replacement Parts

The BMW X6 has run across two main generations: the E71 (2008–2014) and the F16 (2014–2019), and gearboxes from one generation will not cross to the other due to fundamental differences in engine and transmission architecture. Within each generation, fitment depends primarily on your engine code — this is the single most useful detail you can give a breaker, and you'll find it on your V5 or via a VIN check. Even within a generation, confirm with the breaker against your registration, as ancillary and mounting details can vary mid-production.

A 2012 X6 falls in the E71 generation (2008–2014) and a 2015 model sits in the F16 generation (2014–2019), so these are different platforms and the gearboxes are not interchangeable. Always give the breaker your engine code alongside your registration number to confirm compatibility rather than relying on year alone. Never assume fitment across that 2014 generation boundary.

Trim level or badge name alone does not determine gearbox fitment; what matters is the engine code, fuel type, and gearbox type. The xDrive30d and xDrive40d use different diesel engines with different outputs, so their gearboxes are unlikely to interchange directly even if both are diesels from the same generation. Supply your exact engine code (found on the V5 or a VIN check) to the breaker so they can match the correct unit to your car.

No, fuel type is a core fitment factor for gearboxes and a petrol unit will not be a straight swap into a diesel X6. The engine codes, torque ratings, and transmission configurations differ between petrol and diesel variants, so always make sure the donor vehicle shares your exact fuel type. Confirm the engine code match with the breaker against your registration to be certain.

This is something you'll need to confirm with the breaker and your fitting garage rather than assume, as ECU pairing and immobiliser coding requirements can vary and are not something we can state as fact here. Some BMW gearboxes require adaptation or coding to the vehicle using BMW-compatible diagnostic equipment after fitting. Make sure your garage is aware the gearbox is a used unit from a dismantler so they can factor in any required programming steps.

Within the E71 generation the engine code is your most reliable guide — two E71 X6s with the same engine code are the most likely candidates to share a compatible gearbox. However, ancillary and mounting details can change at any point mid-production, so you should always confirm against your specific registration with the breaker rather than relying on year-range alone. Give the breaker your engine code and registration and let them verify the match before you commit.
