2022-2026 Audi Steering Wheel and Vehicle Vibrations TSB

Symptoms

Owners of 2022-2026 Audi vehicles may experience vibrations that are noticeable between 35 and 70 mph. These vibrations can be felt in various parts of the vehicle, including the seat surface, vehicle floor, footwell, pedal cluster, and the steering wheel. The 2022 Audi e-tron steering vibrations, for example, might become more pronounced during braking or acceleration.

Diagnosis / Trigger Conditions

The root cause of these vibrations is often related to tire characteristics, specifically radial force variation. Tires naturally have softer and stiffer areas around their circumference. Radial force variation measures the change in the tire's compression force as it rolls, ideally remaining below 120N (Newtons) peak-to-peak. The first harmonic vibration, which is the strongest component of radial force variation, should be 80N or less.

Another contributing factor can be flat spots that develop on tires after the vehicle has been stationary for some time. While normal, these flat spots can affect balancing measurements and should be driven out by driving prior to any wheel balancing procedure.

Repair Procedure Summary

To address these vibrations, technicians follow a specific diagnostic and repair process. This includes an initial test drive at speeds up to 65 mph to confirm the symptoms. The vehicle is then immediately raised, and the wheels are removed and mounted on a specialized vibration control system, such as the VAS 6230 (GSP9700).

The system measures, balances, and matches the wheels according to precise specifications, ensuring the radial force variation meets the required limits (120N peak-to-peak and 80N first harmonic). If the first harmonic vibration cannot be reduced to 80N by matching, a new tire must be installed. Proper wheel installation is critical, requiring clean contact surfaces, correct centering, and the use of a suitable taper and tensioning device, such as a five-finger tensioning device.

Required Tools or Parts

Specialized equipment is necessary for accurate diagnosis and repair of these vibration issues. Technicians will utilize the VAS 6230 (GSP9700) Road Force Measurement System to analyze tire characteristics. Additionally, the VAS 6243 Clamping Plate is recommended to ensure proper wheel mounting during the balancing process.

Owner Action

If your 2022-2026 Audi is experiencing steering wheel or vehicle vibrations, it is recommended to visit an authorized Audi service center. They can perform the necessary diagnostic procedures and repairs outlined in TSB 2074846/3. While this Technical Service Bulletin is informational, repairs performed on components that were part of the original vehicle delivery may be covered under warranty, subject to Audi's Warranty Policies and Procedures Manual. Always confirm warranty coverage with your dealer for any Audi e-tron steering vibrations or other related issues.
