2021-2025 Audi Cracking/Creaking Noises TSB 2062633/4

Owners of certain 2021-2025 Audi models may experience persistent "cracking/creaking noises during load changes or severe vehicle body torsion." This concern is addressed by Audi Technical Service Bulletin (TSB) 2062633/4, which details the underlying cause and the necessary repair procedure.

Symptoms

Owners typically report various noises and vibrations, especially when the vehicle is under stress. These include:

• "Cracking/creaking noises during load changes or severe vehicle body torsion."
• General noises and vibrations from the vehicle front, passenger compartment, and underbody.
• Snapping noises.
• Crunching, groaning, or crackling sounds.
• Noises originating from the wheel suspension, damping system, or stabilizer bar.

Diagnosis and Trigger Conditions

The root cause of these Audi cracking creaking noises is identified as a quality issue with a bonded joint. Specifically, the bonded joint (-U-) that connects the reinforcement (-P-) on the threaded console (-T-) for the subframe bolted connection to the longitudinal member outer panel (-R-) can come loose. This detachment allows the components to move, generating the audible noises.

The noises are typically heard from the front right and left footwells. They may only become noticeable after driving approximately 10 to 15 kilometers. Owners often report the sounds when pulling away, braking, during vehicle body torsion, or while driving in lower gears during load changes. The presence and intensity of the noise can also be influenced by outside temperature.

Repair Procedure Summary

Audi TSB 2062633/4 outlines a repair procedure to resolve the Audi cracking creaking noises by addressing the loose bonded joint. The detailed steps for this repair are provided in an attached document titled "A4: Cracking_creaking_noises_during_load_changes.pdf," which technicians must consult.

The general repair process involves checking the longitudinal member for issues and then modifying it as needed. Following this, a cavity sealing procedure is performed. Technicians are required to submit photo or video documentation of the complaint, ensuring it includes the Vehicle Identification Number (VIN), the date, and clear, high-resolution visuals of the problem's exact location. This documentation must not contain any personal information such as faces or license plates.
