BMW has issued a Technical Service Bulletin (TSB), identified by NHTSA ID 10200480, addressing customer complaints of whirring or squeaking noises originating from the steering wheel. This 2021 BMW 330i manufacturer_communication specifically targets the steering wheel-mounted airbag assembly in various 2021 BMW models, including the 330i, M340i, M235i, M440i, 228i, 430i, 330e, and Z4.
Symptoms
Owners of affected vehicles, such as the 2021 BMW 330i, may notice a distinct "whirring noise" or "squeaking noise" emanating from the steering wheel area. These noises are particularly noticeable when driving over uneven or rough road surfaces, such as cobblestones.
Diagnosis and Trigger Conditions
The TSB points to the steering wheel-mounted airbag assembly as the source of these sounds. The specific trigger condition for the "whirring noises from the steering wheel" and squeaking is the vehicle encountering rough road surfaces or cobblestones. This suggests that vibrations or movements transmitted through the steering column can cause the airbag assembly components to produce audible friction.
Affected Components
The primary components implicated in this issue are the "STEERING: STEERING WHEEL/HANDLE BAR" and the "AIR BAGS" assembly within the steering wheel. The TSB indicates that the noise stems directly from this critical safety component.
Owner Action
If you are experiencing whirring or squeaking noises from your steering wheel, consistent with this 2021 BMW 330i manufacturer_communication, it is recommended to contact your authorized BMW dealership. Technicians can diagnose the exact source of the noise within the steering wheel-mounted airbag assembly and perform any necessary adjustments or repairs according to BMW's guidelines.
