2021-2023 Audi Clicking Noise from Wheel Bearing TSB

Owners of various 2021-2023 Audi models may experience an Audi clicking noise wheel bearing when driving, especially during low-speed maneuvers or parking. This issue is addressed by Audi Technical Service Bulletin (TSB) 40 22 37 2024318/11, which provides a specific repair method for technicians.

Symptoms

If your Audi is affected, you will typically notice a:

• "Clicking or clacking noise when maneuvering or parking."

This noise can originate from either the front left or front right wheel bearing.

Technical Background

According to Audi, the Audi clicking noise wheel bearing is caused by microscopic movements that occur between the wheel bearing itself and the wheel bearing housing. These minute shifts can create the audible clicking or clacking sound that owners report.

Important Warnings

Owners should be aware of a critical warranty detail outlined in TSB 40 22 37 2024318/11:

• "Tip: Wheel bearings replaced for this concern will not be reimbursed under warranty."

This means that if a wheel bearing is replaced instead of performing the specified paste application procedure, the repair may not be covered under warranty. The TSB is informational only for vehicles outside of warranty.

1. Preparation: Technicians must first remove any corrosion and dirt from the affected wheel bearing and its housing.
