2021-2023 Audi A3, S3, TT, Q3 Steering Noise TSB

Symptoms

Owners of certain 2021-2023 Audi A3, S3, TT, and Q3 vehicles may experience a 2023 Audi S3 steering noise characterized by cracking noises or spring jumps. These sounds are typically noticeable when steering or maneuvering the vehicle.

Diagnosis / Trigger Conditions

This particular 2023 Audi S3 steering noise can often be reproduced under specific conditions. Technicians have found that the noise becomes apparent when at least two people are in the vehicle and the steering wheel is turned just before reaching its right or left stop.

Audi's Technical Service Bulletin 40 23 57 2047758/9 identifies the root cause as the buffer stop for the front shock absorber making contact with the front shock absorber cap. This contact generates the unwanted cracking or spring-like noises.

Repair Procedure Summary

To resolve the cracking noises/spring jumps, Audi's TSB 40 23 57 2047758/9 outlines a straightforward lubrication procedure. Technicians are instructed to lightly lubricate the contact surface between the buffer stop and the front shock absorber cap. Approximately 5 grams of grease, specified by Audi, should be applied to each side.

Additionally, during the service, it is recommended to check the protective sleeve of the front shock absorber. This sleeve should fit correctly and turn easily within the axial deep-groove ball bearing or sleeve bearing to ensure proper function and prevent future issues.
