2021 Audi e-tron Front Suspension Noises TSB

Owners of the 2021 Audi e-tron may experience bothersome Audi e-tron front suspension noises. This issue is specifically addressed by Audi Technical Service Bulletin (TSB) 40 20 17 2061463/1, which identifies a deformed coupling rod as the root cause.

Symptoms

The primary symptom reported by customers is the presence of noises emanating from the front suspension. These Audi e-tron front suspension noises can indicate a problem with the suspension components.

Technical Background

The underlying cause for the front suspension noises is a deformation in the bonded rubber mounting of the coupling rod. This deformation can be visually identified and leads to the audible noises. Audi implemented an improved assembly process starting in September 2020 to mitigate this issue in newer vehicles.

This procedure should follow the guidelines outlined in the ELSA Repair Manual, specifically under the section for Chassis >> Suspension, Wheels, Steering >> Front Suspension >> Front Axle >> Stabilizer Bar >> Coupling Rod, Removing And Installing.

Required Tools or Parts

Technicians will need to consult ETKA for the correct part numbers for the coupling rod (connecting link) and any necessary fasteners, bolts, nuts, and screws. The quantity of coupling rods required will typically be one or two, depending on the diagnosis.

Warranty Information
