2021-2023 Audi Models Cracking Noise Steering TSB

Symptoms

Owners of affected 2021-2023 Audi models may experience specific noises when operating their vehicle. The primary symptom is "cracking noises/spring jumps when steering or when maneuvering." These noises are often noticeable during low-speed maneuvers or when turning the steering wheel to its limits.

Technicians can reproduce the noise by having at least two people in the vehicle and turning the steering wheel just before the right or left stop. If you notice an "Audi S3 cracking noise steering" or similar sounds in other models, this bulletin provides the solution.

Technical Background

Audi Technical Service Bulletin 2047758/10 explains that the cracking noises originate from the front shock absorber assembly. Specifically, the buffer stop for the shock absorber can make contact with the front shock absorber cap, leading to the audible noises described by owners. This contact occurs during steering or maneuvering, causing the unwanted sounds.

Repair Procedure Summary

The repair for the "Audi S3 cracking noise steering" and similar issues across other models involves a straightforward lubrication process. Technicians will lightly lubricate the contact surface between the buffer stop for the shock absorber and the front shock absorber cap. Approximately 5 grams of grease, specifically part number G 000 405 A2, will be applied to each side of the vehicle.

Before applying the grease, it is important to check the protective sleeve of the front shock absorber to ensure it is correctly fitted. The sleeve should turn easily in the axial deep-groove ball bearing or sleeve bearing. This ensures proper function and prevents future issues.

• Grease: G 000 405 A2 (Quantity: 1)
