2019-2025 Audi A6 / S6 / RS 6 Avant Loose Tail Lamp Trim TSB

Audi has issued Technical Service Bulletin (TSB) 66 24 09 2067733/2 to address a condition where the tail lamp trim molding may become loose on certain A6, A6 allroad, S6, and RS 6 Avant models. This bulletin, dated July 10, 2024, supersedes an earlier TSB, Group 66 number 22-90, from August 4, 2022, and includes updated requirements for photo and video documentation during the repair process. Owners experiencing an Audi A6 tail lamp trim loose condition should be aware of this service information.

Symptoms

Owners may notice that the center section of the tail lamp trim molding is pulling away from the bonding strip. A common sign of this issue is a visible gap between the tail lamp trim molding and the rear lid surface. This indicates that the Audi A6 tail lamp trim loose condition is present.

Diagnosis / Trigger Conditions

The root cause of the loose tail lamp trim molding is identified as a weakened bonding strip that attaches the center section of the trim to the rear lid surface. This weakening allows the trim strip to pull away, creating the noticeable gap. Audi has optimized the trim attachment process in production to prevent this issue in newer vehicles.

Repair Procedure Summary

If a compromised or failed adhesion of the tail lamp trim molding is found, the center section of the trim (specifically section 3, as depicted in the TSB's diagrams) must be replaced. Technicians are instructed to follow the detailed procedure outlined in ElsaPro, paying close attention to the preparation of the adhesion surface to ensure a proper and lasting seal.

Required Tools or Parts

For the repair, technicians will need a specific tool:

• VAS 1978/14A: A Hot Air Blower is required for the repair process, likely for proper adhesion surface preparation or curing of the bonding agent.

Important Warnings for Owners

Owners should be aware of the warranty coverage for this repair. If the vehicle is outside of its warranty period (typically 110 up to 6 months/6,000 miles or 1AM over 6 months/6,000 miles), this Technical Service Bulletin is for informational purposes only. This means that repairs for an Audi A6 tail lamp trim loose condition may not be covered under warranty if the vehicle is outside these parameters. All warranty claims must adhere to the Audi Warranty Policies and Procedures Manual.
