2021-2022 Audi Matrix High Beam Calibration TSB

Audi has released Technical Service Bulletin (TSB) 94 21 43 2054161/3, dated July 26, 2021, to provide instructions for the calibration of matrix-design high beams in various 2021-2022 Audi models. This TSB supersedes an earlier bulletin, 19-09, from June 14, 2019, reflecting updated procedures and expanded vehicle applicability.

Symptoms

Owners of affected 2021-2022 Audi vehicles may notice that their headlights require adjustment. The primary concern is specifically related to the advanced matrix-design high beam system. Customers might report the general condition: "Headlights, including matrix-design high beams, need to be adjusted."

Technical Background

Audi has identified that the standard headlight aiming equipment currently in use by service centers does not possess the necessary capabilities to accurately adjust the sophisticated matrix high beams. While the full Matrix Beam functionality is currently deactivated pending approval from the National Highway Traffic Safety Administration (NHTSA), a temporary placeholder value can be entered for the angle calibration.

Once NHTSA approval is granted and the feature is ready for activation, the Audi matrix high beam system will undergo a recalibration with the precise adjustment values to ensure optimal performance.

Repair Procedure Overview

For technicians equipped with specific diagnostic tools, the calibration process involves following detailed instructions. If the specialized VAS 621001 or VAS 621001US tools are available, technicians must adhere to the "Matrix LED Headlamp, Adjusting/Calibrating" procedure outlined in the Elsa Repair Manual.

In situations where these specific tools are not accessible, the TSB instructs technicians to input a value of "0" for all angle measurements within the MXB Calibration Test Plan. This temporary measure ensures a baseline setting until the proper calibration can be performed with the designated equipment.

Required Equipment for Service

To perform the correct calibration procedure, authorized Audi service centers require specific tools. These include the VAS 621001 or VAS 621001US specialized equipment. Additionally, technicians must consult the Elsa Repair Manual for the comprehensive "Matrix LED Headlamp, Adjusting/Calibrating" instructions.

What Owners Should Know

This Technical Service Bulletin (TSB 2054161/3) provides guidance for technicians on how to address the calibration of Audi matrix high beam systems. It's important for owners to understand that this TSB is primarily informational for service centers and is noted as not applicable to any Audi Warranty. Owners experiencing issues with their headlights, especially if they see a message indicating "Headlights, including matrix-design high beams, need to be adjusted," should consult their authorized Audi dealer for diagnosis and service.

Furthermore, the advanced Matrix Beam functionality is currently turned off in these vehicles, pending final approval from NHTSA. Audi plans to recalibrate the system with correct adjustment values prior to activating this feature. This means that while your Audi matrix high beam system may require adjustment now, a further calibration will occur when the full functionality is enabled.
