2022-2025 BMW iX Clicking Sound from Driver's Footwell TSB

Owners of 2022-2025 BMW iX models may notice an unusual "clicking" sound emanating from the driver's side footwell. This issue is addressed by BMW Service Information Bulletin SIB 51 02 25, which provides a detailed procedure for diagnosis and repair. This bulletin, identified as SIB 51 02 25 Revision 1, supersedes the previous version dated January 2025.

Symptoms

The primary symptom is a "clicking" sound heard from the driver's footwell area. This noise typically occurs while driving on both smooth and uneven road surfaces. If you experience a BMW iX clicking footwell sound, this bulletin may apply to your vehicle.

Diagnosis and Trigger Conditions

Technicians should verify the customer's concern regarding the "clicking" sound. The issue is specifically linked to the conditions of driving on smooth and/or uneven roads, which can exacerbate the noise from the driver's footwell.

Cause of the Clicking Sound

The root cause of the BMW iX clicking footwell sound has been identified as the clamp that secures the floor air duct. This clamp has an unfavorable retaining force, leading to the audible clicking. A photo in the bulletin highlights the specific clip on the air duct that generates the sound.

Repair Procedure Summary

The repair outlined in Service Information Bulletin SIB 51 02 25 involves applying felt tape to secure the floor air duct. The procedure is as follows:

1. The technician will first verify the customer's complaint to confirm the presence of the "clicking" sound.
2. The driver footwell upper kick panel must be removed to gain access to the affected area.
3. The driver's side floor air duct is then unclipped and carefully moved aside.
4. Felt tape is applied around the area of the dashboard carrier where the air duct clips onto. This increases the retaining force and prevents the clicking.
5. Finally, the vehicle is reassembled, and the repair is verified to ensure the "clicking" sound has been eliminated.

Required Tools or Parts

The primary part required for this repair is an adhesive pad. The specific part number is:
