2024 Audi A3/Q3/S3/RS3 Front End Noise TSB 2076544/2

Owners of certain 2024 Audi A3, Q3, S3, and RS 3 vehicles may experience a concerning "noise from front end of the vehicle." This issue, addressed by Audi Technical Service Bulletin (TSB) 2076544/2, points to the front anti-roll bar making contact with the subframe.

This TSB, released on February 19, 2025, provides crucial information for diagnosing and resolving the problem, ensuring vehicle safety and owner satisfaction. Understanding the symptoms and the recommended repair can help owners address this specific 2024 Audi S3 front end noise promptly.

Symptoms of Front End Noise

Drivers may notice various types of noises emanating from the front of their vehicle, particularly under specific driving conditions. These sounds are often described as:

• Chattering
• Noises, vibrations -> noise
• Crunching/groaning/crackling
• Creaking noises

These noises are typically heard when turning, when the suspension compresses or extends, or when driving over bumps and speed humps. In some cases, a visual inspection might reveal physical signs such as a scratch, scoring/corrosion, or a damaged component on the anti-roll bar or subframe itself, indicating direct contact.

Diagnosis: Anti-Roll Bar Contact with Subframe

The root cause of the "noise from front end of the vehicle" is identified as the front anti-roll bar resting against the subframe of the front axle. This contact occurs due to a manufacturing defect where the subframe's dimensional accuracy is not within specifications. The TSB includes figures illustrating this contact point, which technicians use to visually confirm the issue.

This specific condition leads to the various noises reported by owners. The constant friction and movement between the anti-roll bar and the subframe create the audible symptoms that alert drivers to the problem. Proper diagnosis involves a thorough inspection of the front axle assembly to confirm the anti-roll bar's contact with the subframe.

Repair Procedure Summary

To resolve the 2024 Audi S3 front end noise, the primary repair detailed in TSB 2076544/2 involves replacing the anti-roll bar if it is found to be resting against the subframe. This ensures that the new component has proper clearance and eliminates the source of the noise. The labor operation for this repair is identified as "Renewing subframe" with code 4007 55XX.

Audi has also implemented a production solution to prevent this issue in newer vehicles. This involves expanding the measuring points during the manufacturing process of the subframe to ensure correct dimensional accuracy from the outset. This proactive measure aims to eliminate the potential for the anti-roll bar to contact the subframe in future production runs.

Warranty Information and Billing

For vehicles covered under warranty, the repair should be performed free of charge. The TSB specifies Service Number 4007 and Damage Code 0010 for warranty claims. It is important for dealerships to follow the Audi Warranty Policies and Procedures Manual when submitting claims.

When billing for this repair, technicians are required to attach photographic or video evidence clearly showing the complaint to DOC-IT. This documentation must include the vehicle's VIN and date, be unedited, in focus, and well-lit. Additionally, the location of the problem should be clearly marked to assist with parts analysis. If the vehicle is outside of any warranty, this Technical Service Bulletin serves as informational guidance.

Important Warnings

• Photo Documentation: Ensure all photo and video evidence for warranty claims includes the VIN and date, is unedited, in focus, and does not show any personal data like faces or license plates. This is crucial for proper claim processing and parts analysis.

Owner Action

If you own a 2024 Audi A3, Q3, S3, or RS 3 and are experiencing a "noise from front end of the vehicle," it is recommended to schedule an appointment with an authorized Audi service center. Inform them about the specific noises you are hearing and mention Technical Service Bulletin 2076544/2. The technicians will be able to diagnose whether the anti-roll bar is contacting the subframe and perform the necessary repair.
