What this part does

The electric power steering rack translates steering wheel input into the lateral movement of the front wheels while providing motorized assist. Mounted directly to the front subframe, this assembly integrates the mechanical rack and pinion with an electric assist motor, torque sensor, and electronic control unit (EPS ECU). It eliminates the need for hydraulic fluid, a power steering pump, and associated lines. When the integrated module or internal motor fails, the vehicle will experience a complete loss of power assist, making the steering wheel exceptionally heavy. A failing unit will also trigger dashboard warning messages and may log communication fault codes within the chassis control system.

Before you order

This replacement steering rack requires programming and initialization to the vehicle using BMW ISTA or an equivalent professional diagnostic tool. Without this coding process, the power assist will remain disabled and fault codes will persist. Please verify your exact OEM part number before purchasing, as BMW models equipped with Integral Active Steering (rear-wheel steering) utilize a completely different front steering rack assembly. Inspect the main electrical connectors on your harness for any signs of water ingress or corrosion prior to installation, as the subframe location makes these connections vulnerable. A full four-wheel alignment is mandatory after installation to calibrate the steering angle sensor and ensure safe handling.
