2021-2024 Audi Wheel Bearing Clicking Noise TSB

Audi has issued Technical Service Bulletin (TSB) 40 23 52 2024318/13 to address a common concern among owners of various 2021-2024 Audi models: an Audi wheel bearing clicking noise. This bulletin, dated March 23, 2023, supersedes an earlier TSB, 40 22-38, from April 14, 2022, and provides updated information regarding affected models, warranty details, and parts.

This TSB specifically targets a "clicking or clacking noise when maneuvering or parking" that owners might experience. The repair involves a straightforward procedure to eliminate the noise.

Symptoms

Owners experiencing this issue will typically notice a distinct "clicking or clacking noise when maneuvering or parking." This sound usually originates from the front left and/or front right wheel bearing area.

Technical Background and Cause

The root cause of the Audi wheel bearing clicking noise is identified as microscopic movements occurring between the wheel bearing and the wheel bearing housing. These minute shifts create the audible clicking or clacking sound that owners report.

Important Warnings

Owners should be aware of a critical warranty detail: "Wheel bearings replaced for this concern will not be reimbursed under warranty." The prescribed repair involves applying a paste, not replacing the bearing itself, under warranty.

Repair Procedure Summary

The repair procedure outlined in TSB 40 23 52 2024318/13 is relatively simple and focuses on eliminating the microscopic movements causing the noise. Technicians will perform the following steps:

1. Preparation: On the affected side(s), any corrosion and dirt must be thoroughly removed from both the wheel bearing housing and the wheel bearing itself.
2. Paste Application: Using a brush, a thin coat of assembly paste, part number G 052109A2, is applied to the wheel bearing housing. Approximately 0.1 ounces or 6 grams of paste (roughly 1/20th of the tube) should be used. Care must be taken to avoid applying any paste onto the threads.

Required Parts and Tools

To perform this repair, the following specific part is required:

• Assembly paste: Part number G 052109A2 (Quantity: 0.1)

Additionally, any necessary fasteners, bolts, nuts, and screws should be referenced and obtained as needed from ETKA/ELSA per the Repair Manual.
