2024-2025 Audi A3/Q3 Front Anti-Roll Bar Noise TSB

Audi has released Technical Service Bulletin (TSB) 2076544/3 to address customer complaints regarding various noises emanating from the front end of certain 2024-2025 Audi A3, S3, RS 3, and Q3 models. This bulletin, last revised on February 26, 2025, specifically targets a condition where the front anti-roll bar makes contact with the subframe, leading to audible disturbances.

Symptoms

Owners of affected Audi vehicles may experience a range of front-end noises, particularly during specific driving conditions. These noises are often described as "noise from front end of the vehicle" and can include:

• "chattering"
• "noise"
• "crunching/groaning/crackling"

These sounds are typically noticeable when turning, during suspension compression or extension, and when driving over bumps or speed humps. If you hear an "Audi A3 front noise" under these circumstances, your vehicle might be affected by this issue.

Diagnosis and Trigger Conditions

According to Audi's workshop findings, the root cause of the "Audi A3 front noise" is the front anti-roll bar resting against the subframe of the front axle. This contact is attributed to a dimensional inaccuracy in the subframe, meaning its manufacturing specifications were not met precisely. Technicians are instructed to visually inspect the anti-roll bar and subframe for signs of contact, including "scratch" marks, "scoring/corrosion," or any indication that the component is "damaged."

Repair Procedure Summary

The prescribed repair for this condition is straightforward: if the anti-roll bar is found to be resting on the subframe, it must be replaced. This replacement aims to install an anti-roll bar that correctly clears the subframe, thereby eliminating the source of the noise. The TSB 2076544/3 does not specify any special tools or parts beyond a new anti-roll bar.

Warranty Information

For vehicles still under warranty, this repair should be covered. Audi specifies Service Number 4007 and Damage Code 0010 for this issue, with Labor Operations listed as "Renewing subframe" under code 4007 55XX. When submitting a warranty claim, dealers are required to attach photos or videos clearly showing the complaint, including the VIN and date. These images must be unedited, in focus, and clearly mark the location of the problem. Owners should be aware that if their vehicle is outside of any warranty, this Technical Service Bulletin is for informational purposes only, meaning the repair cost may fall to the owner.

Owner Action

If you are experiencing a persistent "Audi A3 front noise" or similar sounds from the front end of your 2024-2025 Audi A3, S3, RS 3, or Q3, it is recommended to schedule an appointment with an authorized Audi service center. Clearly describe the symptoms and the conditions under which the noise occurs. You may reference Technical Service Bulletin 2076544/3 to assist the technician in diagnosing the problem. Be prepared to demonstrate the noise if possible.
