2024 BMW X3 Steering Column "Knocking/Thumping" Noise TSB

Owners of the 2024 BMW X3 (G45 E-Series) may notice an unusual "knocking/thumping" noise emanating from the steering column. This noise typically occurs during steering wheel movements and when the wheel returns to the center position. BMW has released Service Information Bulletin SIB 32 05 25, dated May 2, 2025, to address this specific concern, providing a detailed repair procedure for technicians. This issue is identified by BMW repair code 3231213900, which describes "Steering shaft middle section Unpleasant noises."

Symptoms

The primary symptom of this issue is a distinct "knocking/thumping" noise. This noise is audible when the steering wheel is turned and also as it returns to the center position. This specific type of BMW X3 steering column noise can be a source of concern for vehicle owners. BMW has also provided a video, V32 05 25 Column noise, to help technicians identify the exact sound.

Cause

BMW has determined that the root cause of this BMW X3 steering column noise is tension within the steering column. This tension is introduced during the vehicle's assembly process. Relieving this tension is key to resolving the "knocking/thumping" noise.

Repair Procedure Summary

To correct the BMW X3 steering column noise, technicians will perform a procedure to relieve the tension. The process, detailed in SIB 32 05 25, involves several steps:

1. Accessing the Steering Column: The upper and lower steering column shrouds must be removed. This step follows the instructions outlined in BMW's repair procedure REP 32 31 020.
2. Loosening Components: All four nuts securing the steering column connection are loosened.
3. Adjusting the Lever: The adjustment lever (labeled 'A' in the technical document's accompanying photo) is first opened and then closed.
4. Retightening: The four nuts are then tightened in a defined sequence to a specific torque of 21.4 Nm. This precise tightening sequence is crucial for properly relieving the tension.
5. Reassembly and Verification: After tightening, the lower and upper steering column shrouds are reinstalled. The technician will then reassess the complaint to ensure the "knocking/thumping" noise has been eliminated.

Required Parts

While the primary fix involves adjusting existing components, the bulletin does list a specific part that may be used or replaced during the procedure. This is a Torx screw, micro-encapsulated (M14x1.5x25 ZNS3), with part number 07 14 9 890 645. Only one quantity of this screw is typically required. Technicians use the VIN or chassis number to determine the exact part numbers applicable to a specific vehicle via BMW's ETK or AIR systems.
