2022 Audi e-tron GT Speaker Buzzing Noise TSB 2064546/1

Symptoms of Midrange Speaker Buzzing Noise

Owners of 2022 Audi e-tron GT and RS e-tron GT vehicles may notice a specific audio issue: a high-frequency buzzing noise emanating from the midrange speaker. This Audi e-tron GT speaker buzzing noise typically occurs when playing certain music genres or during phone conversations. The noise can be present on the right side, the left side, or both sides of the cabin.

Technical Background

Audi has identified the root cause of the Audi e-tron GT speaker buzzing noise as an inadequate mounting tolerance of the speaker trim on the door panel. The tabs used to secure the speaker trim are not sufficiently robust to prevent vibrations across all frequencies, leading to the audible buzzing.

To address this issue in future production, the mounting tolerance of the speaker trim and the door panel has been optimized. However, vehicles produced within the affected VIN ranges (000001-003853 for Audi e-tron GT and 900000-902247 for Audi RS e-tron GT) may still experience this condition.

Repair Procedure Summary

Technical Service Bulletin 2064546/1 outlines a repair procedure to eliminate the midrange speaker buzzing noise. The process involves applying self-adhesive felt strip material to critical areas to dampen vibrations.

1. Remove Speaker Trim: The midrange speaker trim must first be carefully removed from the door panel.
2. Apply Felt to Door Opening: A section of self-adhesive felt strip material (part number 533 867 910 A) is applied to the lower part of the opening in the door panel where the trim sits. Technicians must ensure this felt is not visible once the speaker trim is reinstalled, as illustrated in Figure 1 of the TSB.
3. Apply Felt to Trim Tabs: Felt strip material is also applied to all the tabs on the speaker trim itself that engage with the door panel opening. Figure 2 in the TSB provides a visual guide for this step.
4. Complete Both Sides: Even if the buzzing noise is only heard on one side, the procedure must be performed on both the right and left side midrange speaker trims to ensure a complete and lasting repair.
5. Reassembly and Inspection: After applying the felt, the speaker trim is reassembled. Technicians then inspect the installation to confirm that no felt strip material is visible.
