2021-2026 Audi Cracking/Creaking Noises During Load Changes TSB

Owners of various 2021-2026 Audi models may experience unusual cracking or creaking noises emanating from the vehicle's front footwells. These noises typically occur during specific driving conditions such as load changes, braking, accelerating from a stop, or when the vehicle body undergoes severe torsion. Audi has released Technical Service Bulletin (TSB) 2062633/6 to provide dealerships with a diagnostic and repair procedure for this issue.

Symptoms of Cracking/Creaking Noises

Customers report hearing distinct cracking or creaking noises, particularly from the front right and left footwells. These Audi cracking creaking noises are most noticeable under the following conditions:

• During load changes, such as acceleration or deceleration.
• When pulling away from a stop or during braking.
• During severe vehicle body torsion, like driving over uneven surfaces.
• While driving in lower gears.
• The noise may be temperature-related and might only become apparent after driving for about 10 to 15 kilometers.

Technical Background of the Issue

The root cause of these noises, as detailed in TSB 2062633/6, is a quality issue with a specific bonded joint within the vehicle's structure. This joint, identified as bonded joint -U-, connects the reinforcement -P- on the threaded console -T- to the longitudinal member outer panel -R-. The threaded console is part of the subframe bolted connection. Over time, this bonded joint may come loose, leading to the audible cracking and creaking sounds during vehicle movements that stress this connection.

Production Solution

Audi has implemented an optimized adhesive in the production process to prevent this issue in newer vehicles. For affected vehicles already on the road, a specific service procedure is required.

Repair Procedure Summary

The repair for the Audi cracking creaking noises involves a detailed analysis and a specific repair process. Technicians must refer to an attached file titled "A4: Cracking_creaking noises during load changes" for the complete instructions. This file illustrates the procedure using the right side of the vehicle as an example, with the understanding that the process for the left side is similar.

Key aspects of the repair procedure include:

1. Noise Analysis: A thorough diagnostic process to confirm the source of the cracking/creaking noises.
2. Bonded Joint Repair: The procedure involves modifying the affected longitudinal member and applying a cavity preservative to secure the bonded joint.
