2021-2024 Audi Rear Dome Light Button Stuck TSB

Audi has issued Technical Service Bulletin (TSB) 2064285/2 to address a common issue where the Audi rear dome light button stuck or becomes inoperative in various 2021-2024 models. This bulletin, dated October 23, 2023, supersedes an earlier TSB, Group 96 number 21-73, from August 18, 2021, with updated model year information.

The TSB provides a detailed procedure for diagnosing and repairing the rear dome light button, ensuring proper function for affected vehicles. Owners experiencing this problem should be aware of the specific repair steps and warranty information outlined by Audi.

Symptoms

Owners of affected Audi vehicles may notice the following symptoms related to the rear dome light:

• The rear dome light can no longer be turned on or off.
• The rear dome light button is found to be stuck or not operational.

Technical Background

Audi's technical analysis indicates that increased pressure on the rear dome light button can cause the trim surrounding the button to separate from its switch base. This separation leads to the button becoming stuck or no longer functioning correctly, resulting in the Audi rear dome light button stuck condition.

Important Warnings

Audi explicitly states that parts replacement does not solve this issue. Claims for replaced parts will be subject to review, indicating that the problem is not with a faulty component but rather with the assembly of the existing parts. Owners and technicians should focus on the reassembly procedure rather than replacing the entire switch.

Repair Procedure Summary

The repair for an Audi rear dome light button stuck or inoperative condition primarily involves reassembling the existing switch components. The procedure outlined in TSB 2064285/2 includes the following steps:

1. Initial Check: If the customer reports the issue, the first step is to verify that the switch trim is properly seated to the switch base.
2. Removal and Inspection: The rear dome light switch must be carefully removed from the headliner. Technicians then need to check if the trim is properly clipped to the switch base. Figure 1 in the TSB illustrates the difference between a dislodged trim and a properly seated one.
3. Reassembly and Reinstallation: If the trim has separated from the base, it should be reassembled correctly and then the entire switch reinstalled back into the vehicle.

This procedure emphasizes that the issue is mechanical and can be resolved by ensuring the trim is correctly attached to the switch base.
