2021 Audi e-tron Digital Matrix LED Headlamps Misalignment

Audi has released Technical Service Bulletin (TSB) 9403 UPDATE to proactively address a potential issue with the Digital Matrix LED headlamps in certain 2021 Audi e-tron vehicles. This update ensures proper functionality and alignment of the headlamp features.

Symptoms

Owners of affected 2021 Audi e-tron models may notice that the "coming home feature display from the Digital Matrix LED headlamps may be misaligned." This condition specifically affects the projected display from the headlamps, not necessarily the main beam alignment.

Fault Codes / Campaign Information

This update is triggered by the presence of the 9403 code in the Elsa Campaign/Action Information screen. This code indicates that the vehicle is eligible for the headlamp calibration procedure outlined in this TSB. Dealers must verify this code in Elsa on the day of repair to confirm eligibility.

Important Warnings

Audi has issued critical instructions for technicians performing this update:

• "All Safety Recalls must be completed prior to completing this campaign."
• "Horizontal adjustments MUST NOT BE MADE!!" The caps on the horizontal adjustment screws must remain in place. This emphasizes that the issue is a calibration matter, not a physical adjustment of the horizontal aim.

Diagnosis and Eligibility

To determine if a 2021 Audi e-tron is eligible for this update, a GFF Diagnostic scan must be performed. Vehicle eligibility is confirmed through the Elsa Campaign/Action Information screen, which must show the 9403 code as "open." The vehicle must also be within its New Vehicle Limited Warranty period.

The repair involves a guided calibration process for the Digital Matrix LED headlamps. Technicians will perform the following steps:

1. GFF Diagnostic Scan: Initiate a GFF Diagnostic scan on the vehicle.
