Second Hand BMW i7 Transfer Box

The BMW i7 is a fully electric vehicle and does not have a conventional transfer box. In all-wheel-drive xDrive variants, power is distributed between the front and rear axles electronically via separate motors rather than through a mechanical transfer box, gearbox, or propshaft arrangement. If you are looking for a drivetrain component, you may actually need a front or rear drive unit (electric motor and reduction gear assembly), and a breaker can advise which unit applies to your axle.

The i7 xDrive60 does not use a transfer box at all; its all-wheel-drive system relies on two independent electric drive units rather than a mechanical centre diff or transfer case. The fault is more likely to be within one of the front or rear drive units, the high-voltage inverter, or associated control electronics. Describe your symptoms to a breaker or EV specialist and quote your VIN so they can identify the correct drive unit for your variant.

No - the rear-wheel-drive i7 eDrive50 has a single rear electric drive unit and no transfer box whatsoever, as there is no second axle to transfer power to. The part you are likely after is the rear drive unit itself, sometimes listed by breakers as the rear electric motor or rear e-axle assembly. Supply your full VIN to any breaker so they can match the correct unit to your vehicle's output rating and software level.

No - the i7 is a purpose-built electric vehicle and shares no drivetrain components with combustion-engined 7 Series models such as the G11/G12 generation or the G70-generation 740i or 750e. Even where bodyshell or interior parts may cross over, mechanical drivetrain parts are entirely incompatible because the i7 has no engine, no conventional gearbox, and no transfer box. If you need a drivetrain part for your i7, search specifically for i7 front or rear drive units rather than 7 Series transfer boxes.

None of the i7 trim variants - including the eDrive50, xDrive60, or high-performance M70 - are fitted with a transfer box, regardless of specification or build date. The M70 uses two high-output electric motors working together electronically, which is a fundamentally different system to the mechanical transfer cases found in combustion or hybrid four-wheel-drive vehicles. If you are chasing an AWD drivetrain fault on any i7 trim, speak to a breaker about front or rear drive units rather than a transfer box.
