2022 BMW iX Steering Gear Replacement Service Action

Important Warnings for High-Voltage Systems

BMW emphasizes critical safety warnings when working on high-voltage (HV) systems in their vehicles. Repairs involving disconnecting or removing high-voltage battery components must only be performed by properly trained personnel who have completed all applicable HV Technical Training Courses. Unqualified individuals performing such work risk severe injury or damage to the vehicle. Specific safety instructions are detailed in Repair Instruction 61 00, titled "Observe safety instructions when handling electric vehicles."

Before any HV component is disconnected or removed, the HV system must be disabled and secured using the HV Service Disconnect Switch and lock out. This procedure requires a properly trained HV technician with a minimum HV Qualification level, achieved by completing courses such as "ST2324 High Voltage Drivetrain Systems."

For Generation 5 vehicles, specific training is required to diagnose, remove, and service any HV component. Non-HV certified technicians are explicitly NOT allowed to work on the high-voltage system.

Symptoms

Owners of affected 2022 BMW iX vehicles may notice a specific Check Control message displayed on the instrument cluster. This message will read: "Steering behavior. Drive slowly and have this checked by the nearest Service Provider." Concurrently, there will be a noticeable reduction in power steering support, particularly during maneuvering.

Cause of the Issue

The root cause of the reduced power steering support and the warning message in the 2022 BMW iX is a faulty capacitor located within the Electric Power Steering (EPS) gear. This component defect impairs the proper function of the power steering system.

Repair Procedure Summary

The correction for this issue, identified as Service Action SIB 32 01 24, involves replacing the Electric Power Steering (EPS) gear. The procedure follows the guidelines outlined in repair instruction REP32 13 572. After the physical replacement, the vehicle's control units will undergo programming and encoding to update to the required I-level or higher. This process also includes a vehicle test.

Associated work procedures that are included in this service action are:

• Commissioning and initialization of the new electromechanical steering gear.
• Checking wheel alignment using the Kinematics Diagnosis System, which includes measuring ride height without vehicle loading.
• Adjusting the toe-in on the front axle.

Additional work may also be performed, such as adjusting the rear axle or renewing eccentric screws, and activating integral active steering (HSR) if applicable.
