Second Hand BMW iX Transfer Box

Yes, but only on the xDrive variants — the iX xDrive40 and iX xDrive50 — which use dual electric motors to drive all four wheels; these models do have a transfer unit distributing drive between axles, so a transfer box is a legitimate part to source for them. The rear-wheel-drive single-motor variants do not have a transfer box at all, so if your iX is a single-motor model you would not be looking for this part. Check your V5 or run a VIN check to confirm which drivetrain your vehicle has before quoting.

The BMW iX (I20) launched in 2021 and has continued as a single generation through to the current model, so there is no major generational break to navigate, but BMW does make running production changes that can affect ancillary mounting or electronic pairing mid-cycle. The drive unit layout is fundamentally the same across the 2021-onwards xDrive models, which is a positive sign for compatibility, but whether a specific unit from a 2021 or 2022 car will drop straight into a 2023 or 2024 example — including any ECU or software matching — is something you must confirm with the breaker against your exact registration. Always supply your VIN to the breaker so they can cross-reference part numbers directly.

Trim level does not determine transfer box fitment on the BMW iX — what matters is the drivetrain variant (xDrive40 or xDrive50) and the associated drive unit specification, not whether your car is a standard, Sport, or M Sport. You may find cosmetic or suspension differences between trim levels, but the transfer unit itself follows the mechanical specification, not the badge or interior grade. Confirm the exact drive unit part number with the breaker against your registration to be sure.

The iX M60 is a higher-output dual-motor xDrive variant, and while it shares the same basic all-wheel-drive architecture as the xDrive50, the M60's drive units are tuned for significantly more power and torque, which makes it very likely the transfer components differ from the standard xDrive50. You should not assume cross-compatibility between the M60 and the xDrive50 transfer units without confirming part numbers with the breaker against both registrations. Treat the M60 as a distinct mechanical specification and supply your VIN to any breaker you approach.

The xDrive40 and xDrive50 use different output drive units designed around different power and torque ratings, so the transfer components are not straightforwardly interchangeable despite both being xDrive all-wheel-drive models. There is also the question of whether control units or software would need to be matched to your specific vehicle, which is something you must confirm with the breaker and ideally your BMW specialist before purchasing. Do not assume the cheaper xDrive40 unit is a straight swap for an xDrive50 without a part-number match against your VIN.

Give the breaker your full VIN rather than just the year and badge, as this lets them identify the exact drive unit specification — xDrive40, xDrive50, or M60 — and cross-reference the correct part number for your vehicle. The drivetrain variant is the most critical detail for this part, so also confirm whether your car is the dual-motor all-wheel-drive version, since single-motor iX models do not have a transfer box. Be aware that ECU pairing and any software calibration required after fitting are questions to raise with the breaker and your installer before you commit to a purchase.
