Second Hand BMW i4 Steering Box

No — the BMW i4 does not have a steering box. Like virtually all modern passenger cars, the i4 uses electric power steering with a rack-and-pinion system, not a recirculating-ball steering box. If your steering is faulty, the part you are most likely looking for is the steering rack, the electric power steering motor, or the steering column assembly — ask a breaker for the correct part against your registration.

Because the i4 uses a rack-and-pinion electric power steering system, the serviceable steering components you can source from a breaker include the steering rack, the electric power steering motor/actuator, the steering column, and the steering pump if applicable. There is no steering box on any variant of the i4, including the eDrive35, eDrive40, M50, or xDrive variants. Quote requests to breakers should specify your exact registration so they can match the correct rack assembly for your drivetrain configuration.

Yes, it can matter — the steering rack and associated components may differ between the rear-wheel-drive eDrive35 and eDrive40 and the four-wheel-drive M50, as weight distribution, power output, and axle configuration can influence steering assembly specification. There is no steering box on any of these variants; the part category does not exist on this model. Always confirm the correct steering rack or column part against your registration with the breaker before purchasing.

The BMW i4 first generation launched in 2021, with a notable update arriving for the 2024 model year; whether steering rack components interchange across that boundary is not something that can be confirmed without checking part numbers. Regardless, there is no steering box on the i4 at any point in its production — if you have been quoted a steering box, query this with the breaker as it is not the correct part for this vehicle. Confirm the exact steering component you need against your registration with the breaker to ensure compatibility.

Trim level itself does not affect fitment in the way cosmetic features do, but the drivetrain configuration that comes with different trim levels — such as rear-wheel drive on the eDrive40 versus all-wheel drive on the M50 — can affect which steering rack assembly is correct. There is no steering box on any trim of the i4, so if a listing describes the part as a steering box it is incorrectly categorised. Confirm the correct steering rack or column part with a breaker using your registration number.

You will not find one because the BMW i4 has never been fitted with a steering box — no variant of this fully electric vehicle uses that type of steering system. The i4 uses a rack-and-pinion electric power steering setup throughout its range, so the part you need is most likely a steering rack, electric steering motor, or steering column. Contact a breaker with your registration and describe the symptoms or the component that is actually faulty, and they will identify the correct part for you.
