BMW X1/X2 Steering Knocking Noise TSB SIB 32 06 25

BMW has released Service Information Bulletin (SIB) 32 06 25, dated June 2, 2025, to address a specific steering system concern affecting certain 2023-2025 BMW X1 (U11) and X2 (U10) models. Owners may experience a "knocking/thumping” noise from the steering system, which can be a cause for concern regarding vehicle handling and comfort.

This bulletin provides technicians with a clear procedure to diagnose and correct the issue, ensuring proper function and eliminating the unpleasant noise. The repair is covered under the BMW New Vehicle Limited Warranty.

Symptoms

Owners of affected BMW X1 and X2 vehicles may notice a distinct "knocking/thumping” noise. This sound is typically heard during left or right steering wheel movements, particularly when the vehicle is stationary or moving at low speeds. The noise can also be felt directly in the steering wheel, indicating a mechanical issue within the steering column.

A key characteristic of this issue is its dependence on temperature. The noise is more pronounced when the vehicle's interior temperatures are high, specifically above 86°F. Conversely, the noise tends to diminish as the vehicle's interior cools down.

Cause

The root cause of the "knocking/thumping” noise has been identified as tension within the steering column components. Specifically, the tension occurs between the steering shaft universal joint and the steering gear input shaft. This misalignment or improper seating creates friction or play that manifests as the audible knocking or thumping sound, impacting the smooth operation of the steering system.

Repair Procedure Summary

BMW Service Information Bulletin SIB 32 06 25 outlines a precise procedure for technicians to correct the steering system noise. The repair focuses on the re-alignment of the steering shaft universal joint to the steering gear input shaft. The steps involve:

Accessing the Universal Joint: The technician will begin by removing the driver's footwell trim to gain access to the universal joint, which is a critical component connecting the steering shaft to the steering gear.
Inspection: A visual inspection will be performed to check if the universal joint is tilted in comparison to the steering gear input shaft. This tilt indicates the source of the tension.
Re-alignment: If a tilt is observed, the bolt securing the universal joint will be removed. The input shaft will then be carefully inserted into the universal joint, ensuring it is fully seated to eliminate any tension or misalignment.
Securing the Joint: A new bolt (Part Number 07 11 9 908 429) will be installed and tightened to a specific torque of 28 Nm (20.7 ft-lb). It is crucial to ensure that the universal joint does not twist during this tightening process to maintain proper alignment.
Verification: After the re-alignment and tightening, the steering system will be re-assessed to confirm that the knocking or thumping noise has been eliminated.
Reassembly: Finally, the driver's footwell trim will be reinstalled.

For a visual guide, technicians can refer to video V32 06 25, which supports this bulletin.

Required Tools or Parts

For this repair, a specific part is required: a Star-socket screw, identified by Part Number 07 11 9 908 429 (BM10X35-10.9). This screw is used to secure the universal joint after re-alignment. Technicians should use the VIN/chassis number in ETK or AIR to determine the exact part number applicable to the specific vehicle being repaired, as equipment and options can vary.
