BMW 7 Series Transfer Box Replacement Parts

Only the xDrive four-wheel-drive variants of the BMW 7 Series have a transfer box — it is the unit that splits drive between the front and rear axles. Rear-wheel-drive 7 Series models (which make up the majority of the range) do not have a transfer box at all, so if you have a standard RWD car you will not find this part on your vehicle. Check your V5 or run a VIN check to confirm whether your car is xDrive before searching for this part.

The xDrive four-wheel-drive option was introduced on the F01/F02 generation (2008–2015, with a facelift in 2012) and carried through to the G11/G12 generation (2015–2022, facelift 2019). The E65/E66 generation (2001–2008) did not offer xDrive in any meaningful volume for the UK market, so a transfer box for that era is not a realistic search. Always confirm your exact generation against your registration before ordering.

The F01 generation runs from 2008 to 2015, with the facelift arriving in 2012, meaning both a 2012 and a 2014 car sit within the same overall generation. However, whether the transfer box itself changed across the 2012 facelift boundary is something you should confirm with the breaker against your exact registration and engine code, as ancillary and mounting details can change mid-production without a full model change. The engine code from your V5 is the most useful detail to give the breaker when checking compatibility.

Trim level — whether your car is an SE, M Sport, or any other badge — does not affect transfer box fitment; what matters is whether the car is xDrive and, above all, the engine code. Two xDrive 7 Series cars with the same engine code should take the same transfer box regardless of trim, though you may find minor cosmetic or ancillary differences on the unit when it arrives that are unrelated to function. Give the breaker your engine code (found on your V5 or via a VIN check) and confirm it is an xDrive model for the most reliable match.

Yes — the engine code is the single most important detail for transfer box fitment, more so than the year or badge on the car. Different engines within the same xDrive generation can pair with different transfer box specifications, so two cars of the same year but different engine codes may not share the same unit. Find your engine code on the V5 logbook or via a VIN check and pass it to the breaker before agreeing a purchase.

Whether a used transfer box requires ECU pairing, software coding, or any immobiliser-related work after fitting is something you should confirm directly with the breaker and your fitting garage, as this can vary and Findapart cannot state this as fact for your specific vehicle. It is worth asking the breaker whether the unit they are selling is a direct swap or whether specialist programming will be needed, so you can factor in any additional cost before committing.
