2021-2025 Audi Q8 Front Door Speaker Noises TSB

Audi has released Technical Service Bulletin (TSB) 2068839/2 to address customer complaints regarding noises emanating from the front door loudspeakers in certain Q8, SQ8, and RS Q8 models. This bulletin, dated November 16, 2023, supersedes an earlier TSB, Group 91 number 22-55, from December 7, 2022, with updated information including additional model years and a change in the recommended thread-locking fluid.

This TSB specifically targets the Audi Q8 front door noise issue, providing a clear diagnostic path and repair procedure for technicians. Owners experiencing these symptoms should be aware of this official Audi communication.

Symptoms

Owners of affected Audi vehicles may notice the following symptoms related to this issue:

• "Rattling, clattering or droning noises from front door."

These noises are typically heard when the vehicle is in operation, especially when driving on rough roads or when vibrations from music are present. The source of the Audi Q8 front door noise has been identified as the front door loudspeakers.

Technical Background

Audi's workshop findings indicate that the mounting frame for the bass loudspeaker is the source of the noises. The primary cause is identified as securing bolts that have come loose over time. The technical background explains that temperature fluctuations and vibrations, including those from music, can lead to a loss of torque at the securing bolts of the front door loudspeaker mounting frame.

Repair Procedure Summary

To resolve the Audi Q8 front door noise, technicians are instructed to perform the following steps as outlined in TSB 2068839/2:

1. Inspect Bolts: All loose bolts associated with the front door loudspeaker mounting frame must be checked for any signs of damage. If damage is identified, the bolts must be replaced.
2. Apply Thread-Locking Fluid: The bolts must be refitted using a medium-strength thread-locking fluid. Audi specifically recommends Loctite® 242® or an equivalent product.
3. Tighten to Specification: The bolts must then be tightened to the precise torque specifications detailed in the Elsa repair manual. Technicians should refer to the section: "Electrical System>>Communicaton>>91 Communication>>Sound System>> Left Front Bass Speaker -R21-/Right Front Bass Speaker -R23-, Removing and Installing."
