Second Hand BMW iX1 Transfer Box

Only the xDrive (four-wheel-drive) variants of the BMW iX1 (U11, from 2022 onwards) have a transfer box — it is the unit that splits drive between the front and rear axles on the all-wheel-drive system. The sDrive variants are front-wheel-drive only and have no transfer box whatsoever, so if your iX1 is badged sDrive you will not find this part on your car. Check your V5 or run a VIN check to confirm whether your car is xDrive before searching further.

The BMW iX1 (U11 generation, launched late 2022) is a single generation covering both 2023 and 2024 models, so there is no generation boundary between those years and the xDrive transfer box is broadly the same unit across that span. That said, BMW does make running production changes, so confirm with the breaker that the part number on the donor unit matches your registration before buying. Never assume fitment without that check.

Trim level makes no difference whatsoever to the transfer box on the iX1 xDrive — xLine, M Sport, and any other trim all share the same drivetrain components because trim only affects cosmetics, interior specification, and suspension tuning. What matters is that both cars are xDrive (not sDrive), and that the engine codes match, so supply your engine code (found on the V5 or via a VIN check) to the breaker rather than quoting your trim name. You may notice cosmetic differences when collecting the part but the mechanical unit itself will be the same.

Yes, the iX1 xDrive30 is the all-wheel-drive petrol variant and it does have a transfer box. When sourcing a used unit, give the breaker your exact engine code (not just the xDrive30 badge) because that is the definitive identifier — the badge alone does not confirm every mechanical detail. The breaker can then match the donor unit correctly against your registration.

No — the iX1 (U11, 2022 onwards) is a fundamentally different platform from the F48 X1 (2015–2022) and the two transfer boxes are not interchangeable. The U11 iX1 xDrive uses an electrically-driven rear axle motor arrangement rather than a conventional mechanical transfer box of the type found on earlier X1 models, meaning the entire drivetrain architecture is different. You must source a unit specifically from a U11 iX1 xDrive.

Whether the replacement transfer box requires any ECU pairing, software adaptation, or coding to your specific vehicle is something you must confirm directly with the breaker and your installer, as this depends on the vehicle's systems and any control modules associated with the unit. It is sensible to ask a BMW-specialist independent garage or a main dealer about this before fitting. Do not assume the unit will function fully without any adaptation work.
