Audi has released Technical Service Bulletin (TSB) 66 24 12 2060333/5 to address a common concern regarding the discoloration of exterior black optic trim on various 2022-2024 Audi models. This bulletin, which supersedes TSB Group 66 number 23-03 dated October 24, 2023, provides guidance for diagnosing and repairing this cosmetic issue. Owners experiencing Audi e-tron trim discoloration will find this information helpful.

Symptoms of Discolored Black Optic Trim

Owners may notice that their vehicle's exterior black optic trim appears discolored. The specific symptom described by Audi is: "The exterior trim on a vehicle with black optic package is discolored. It appears to take on a red or purple hue and, in some cases, may take on a grey or metallic appearance." This discoloration can affect the aesthetic appeal of the vehicle.

Technical Background

Audi's investigation into the discoloration revealed a manufacturing defect. The technical background states that "The ultraviolet radiation resistance in the trim coating was found to be insufficient." This means the original coating on the black optic trim was not adequately protected against prolonged exposure to sunlight, leading to the observed color changes.

Important Warnings for Owners and Technicians

Audi provides specific instructions and warnings related to this TSB:

• Scope of Application: This TSB is specifically for the described discoloration of black optic trim. It "is not to be applied in cases where any other issue with a black optic trim piece or an issue with a non-black optic trim piece is discovered." This ensures that the correct repair is performed for the specific problem.
• Warranty Coverage: For vehicles outside of their warranty period, this Technical Service Bulletin is informational only. Owners should verify their warranty status with an authorized Audi dealer.
• Documentation Requirement: Technicians are required to take photos of the customer's concern and upload them into the DOC-IT system with the repair order. These photos must include a date stamp, VIN reference, and be in focus with sufficient lighting. This helps ensure proper documentation and warranty claim processing.

Repair Procedure Summary

The recommended repair for the Audi e-tron trim discoloration involves replacing the affected trim piece. If the symptom described in TSB 66 24 12 2060333/5 is present, the technician will identify and replace the discolored black optic trim. The labor operations associated with this repair involve removing the old trim and installing a new one. No specific parts or tools are listed beyond the replacement trim itself, indicating a straightforward component swap.

For eligible vehicles under warranty, the repair can be claimed using the following codes:

• Service Number: 6663
• Damage Code: 0031

All warranty claims must adhere to the Audi Warranty Policies and Procedures Manual.

Production Solution

To prevent this issue in newly manufactured vehicles, Audi has implemented a production change. "Improved trim coating is implemented into production," meaning that newer vehicles should have black optic trim with enhanced UV radiation resistance, reducing the likelihood of future discoloration.
