Symptoms

Owners of affected 2021-2024 Audi vehicles may notice an Audi steering squeak emanating from the steering column. This squeaking noise is particularly apparent when steering slowly. The sound may also become louder at higher temperatures or after longer driving periods, indicating a potential issue with the intermediate steering shaft.

Technical Background

Audi's Technical Service Bulletin 48 23 43 2055733/4 explains that the squeaking noise originates from the rubber boot of the intermediate steering shaft. Specifically, the noise is caused by the sealing sleeve (also known as the sealing lip) where the steering shaft rests on its cone. This condition is attributed to incorrect positioning of the sealing sleeve in the bulkhead, combined with unfavorable manufacturing tolerances of the components involved.

1. Disconnect the intermediate steering shaft from the steering column.
2. Loosen the rubber sealing sleeve and then push it upwards as far as possible. Once repositioned, the sleeve is retightened.
3. Reinstall the steering intermediate shaft to the steering column, using new bolts for secure attachment.
