Fitment questions
Does the BMW M8 have a transfer box?
The BMW M8 is available with rear-wheel drive only or with BMW's xDrive four-wheel-drive system, and only the xDrive variants have a transfer box — the rear-wheel-drive M8 has no transfer box at all. If you're not sure which drivetrain your car has, check your V5C or run a VIN check, as the drivetrain type should be listed there. If you have a rear-wheel-drive M8 and are experiencing transmission issues, you may be looking for a different component such as the differential or gearbox.
Will a transfer box from an early BMW M8 xDrive fit my later M8 xDrive?
The BMW M8 (F91/F92/F93) was produced from 2019 onwards as a single generation, all sharing the S63 4.4-litre twin-turbocharged V8 engine, which is the most important factor for transfer box compatibility. Within that generation, year-to-year fitment is broadly consistent, but you should confirm with the breaker against your exact registration and engine code, as ancillary or mounting changes can occur mid-production without a formal model-year boundary. Always supply your engine code — found on your V5C or via a VIN check — when requesting a quote from a breaker.
Does the trim level affect which transfer box I need — for example, does an M8 Competition xDrive use a different transfer box to a standard M8 xDrive?
Trim level does not affect transfer box fitment — the transfer box is determined by drivetrain layout and engine code, not by whether the car is a standard M8 xDrive or an M8 Competition xDrive. Both variants use the S63 V8 engine with xDrive, so a used transfer box from either should be mechanically equivalent. That said, confirm the part number with the breaker against your registration to be sure, as there is always a possibility of minor running changes.
My BMW M8 xDrive is showing a transfer box fault — could I fit a used one, or does it need coding to the car?
A used transfer box can physically fit your M8 xDrive provided it comes from a compatible xDrive variant with the same engine code, but whether the unit requires ECU pairing or immobiliser coding to your vehicle is something you must confirm directly with the breaker and your fitting garage before purchasing. Some transfer box units on modern BMWs can involve electronic matching to the vehicle's control systems, and this could affect whether a straight swap is straightforward. Make sure you raise this question explicitly when getting quotes from breakers on Findapart.
Can I use a transfer box from a BMW M8 Gran Coupé xDrive in a standard M8 Coupé xDrive?
The body style — Coupé, Gran Coupé, or Convertible — does not determine transfer box fitment; what matters is the drivetrain layout and engine code, both of which are the same S63 V8 with xDrive across all M8 body styles. A transfer box from an M8 Gran Coupé xDrive should therefore be mechanically relevant to an M8 Coupé xDrive, but you should always confirm compatibility with the breaker against your specific registration number. Minor ancillary or mounting differences between body styles cannot be ruled out without the breaker checking part numbers directly.
