Customer states:
There is a visual concern or defect present with the headlight(s) or taillight(s).

Technical Background
For visual concerns related to a headlight or taillight submitted under warranty, we ask that defect flags and
photos be used to identify and document the visual concern or defect. Photos should be uploaded to DOC-IT in
case they are needed during the review.
Note:
Defect flags can be found in the attachment tab of this TSB. These can be printed and used as needed.

Production Solution
Not Applicable

Service
1. Before any repairs are made or components are removed, please fill out the defect flag and take photos as
shown below.
2. When returning headlights or tail lights to the WPRC, use the new part packaging and take necessary
precautions to avoid damage during shipping.

3. When to use the defect flags and photo documentation:
- Moisture buildup (please see associated TSBs below before proceeding).
- Foreign objects or loose components inside the lamp.
- Haze, pitting, cracking, bubbles, or markings on the inside of the lens.
- If the concern is NOT related to outside influence and a warranty claim is submitted.
4. Three (3) photos are needed for the lamp to be replaced:
- 1 perspective view – showing the general area and identifies which lamp is affected.
- 1 close-up – clearly focused and showing the customer concern.
- 1 production label – shows the entire production sticker or label.
Note:
If another TSB is applicable as seen in the two examples below, please follow all other primary TSBs before
proceeding:
• TSB 2012749: 94 Exterior lights, moisture accumulation (All models).
• TSB 2058420: 94 Tail light or front indicator in bumper is cracked, broken, leaks, or does not work (Q3, Q5,
Q7, Q8, Audi e-tron quattro, and Audi e-tron Sportback).
Perspective photo:
• Entire area is visible in the photo which clearly identifies the lamp affected (figures 1 – 2).
• Photo is taken with the fault component still installed on the vehicle before components are removed.
• Photo is in focus and properly lit.
• Defect flag should be completely visible and legible.
The first photo should show a full picture of the affected component and the affected area of the cause
should be marked with an arrow. This is for guidance.
