2018-2021 Audi Black Optic Trim Discoloration TSB

Symptoms of Black Optic Trim Discoloration

Owners of affected 2018-2021 Audi vehicles may notice that the exterior black optic trim on their vehicle appears discolored. This discoloration can manifest in several ways, altering the aesthetic appeal of the vehicle's trim.

Specifically, the trim may take on a "red or purple hue". In other instances, the trim might exhibit a "grey or metallic appearance". These visual changes indicate a degradation of the trim's surface.

Technical Background: Why the Trim Discolors

Audi's Technical Service Bulletin (TSB) 2060333/3 identifies the root cause of the Audi black optic trim discoloration. The issue stems from the trim coating's "insufficient ultraviolet radiation resistance". Over time, exposure to sunlight causes the coating to break down, leading to the observed color changes.

This lack of UV protection means the trim is not adequately shielded from environmental factors. The degradation of the coating results in the visible discoloration, impacting the vehicle's finish.

Production Solution Implemented

To prevent this issue in newly manufactured vehicles, Audi has implemented an improved trim coating in its production process. This updated coating offers enhanced "ultraviolet radiation resistance", addressing the underlying cause of the discoloration.

This change ensures that newer vehicles produced after the implementation date will have more durable black optic trim. The production solution aims to provide long-term protection against UV damage and discoloration.
