Used BMW i4 Transfer Box

No – the BMW i4 does not have a transfer box on any variant. The i4 is a purely electric vehicle built on BMW's CLAR platform; even the all-wheel-drive xDrive versions (the i4 M50 and eDrive40 in AWD configuration) achieve four-wheel drive through two separate electric motors rather than through a conventional transfer box, gearbox, or prop shaft arrangement. If your i4 is losing drive or you have a fault in the drivetrain, the component you are likely looking for is an electric drive unit (front or rear motor-and-reduction-gear assembly), a power electronics module, or possibly an EV-specific differential unit – speak to a breaker who specialises in electric BMW parts and give them your full VIN so they can identify the exact drive unit fitted to your car.

Almost certainly not – no BMW i4 was ever built with a transfer box, as the car has no combustion engine, no traditional gearbox, and no mechanical link between axles of the kind a transfer box provides. It is possible the breaker or seller has misidentified the part, or that there has been a mix-up with another BMW model such as the xDrive variants of the 3 Series or 5 Series, which do carry transfer boxes. Double-check the part description and give the breaker your VIN to confirm they are quoting for the correct vehicle and the correct component.

Depending on your symptoms or repair need, the relevant electric drivetrain parts on the i4 include the rear electric drive unit (fitted to all i4 variants), the front electric drive unit (fitted to the dual-motor M50 and xDrive versions), power electronics or inverter modules, and high-voltage battery components. Because these parts are electronically paired to the vehicle and may require coding, always confirm with the breaker that the unit from a donor car is compatible with your exact VIN before purchasing. Specialist EV dismantlers are your best starting point as general breakers may not stock or correctly identify i4 electric drivetrain components.

Yes – year and specification matter significantly for electric drive units on the i4, even though there is no transfer box involved. The i4 launched in 2021 and received updates through its production run, and the drive units, software, and connectors on earlier cars may differ from later ones; always provide your full VIN or engine/motor code to the breaker rather than relying on year alone. Whether your car is an eDrive40 (single rear motor) or M50 (dual motor) is the most critical distinction, as the drive units are entirely different between those variants. Confirm compatibility and any coding requirements directly with the breaker against your registration before buying.
