2021-2023 Audi e-tron Rear Axle Ticking Noise TSB

Symptoms

Owners of certain Audi e-tron models may experience a distinct Audi e-tron ticking noise or vibration. This issue is specifically noted as a "Vibrations and/or ticking noise from rear of the vehicle at <5 km/h." The sound originates from the area of the rear axle.

This condition is most noticeable during slow-speed operations, typically when the vehicle is moving at less than 5 kilometers per hour (approximately 3 miles per hour). The Audi e-tron ticking noise can be consistently reproduced under these specific driving conditions.

Technical Background

Audi has identified that the vibration and/or ticking noise heard during slow-speed operations originates from the electric drive motor located on the rear axle. This indicates a mechanical or operational characteristic of the rear drive motor itself, rather than an external factor.

This issue affects specific models including the 2019, 2021-2023 e-tron quattro and 2020-2023 e-tron Sportback quattro. The manufacturer is actively working to develop a permanent solution for this rear drive motor noise.

Important Warnings for Owners

Audi has issued a critical advisory regarding this condition: Do not replace any components for this condition since this will not resolve the customer's concern. This means that attempting to replace parts like the electric drive motor or other rear axle components will not fix the Audi e-tron ticking noise and could result in unnecessary costs or effort.

Owners are advised to wait for the official solution from Audi. Dealers are instructed to inform customers that a fix is expected to be available by the end of the fourth quarter of 2023, though this timeline is subject to change. This TSB (93 23 29 2071382/1) is for informational purposes only and does not cover warranty claims for replacement parts related to this specific issue.

Current Status and Next Steps

As of September 13, 2023, Audi states that a solution for the Audi e-tron ticking noise is currently under development. The Technical Service Bulletin 2071382/1 will be updated once more information and a definitive fix become available.

In the interim, technicians are required to create a Pending Service Solutions (PSS) record for any customer complaints related to this issue. This process helps Audi track the prevalence of the problem and ensures that customers are documented for future resolution. Owners should contact their authorized Audi dealership for the latest updates on the availability of the solution.
