2024 Audi Models Control Module Coding Issue

Owners of various 2024 Audi models may encounter an Audi control module coding failure when a replacement control unit is installed. This issue, detailed in Technical Service Bulletin (TSB) 00 23 72 2071338/1, prevents the successful completion of the replacement test plan after a new module has been fitted.

This TSB specifically addresses a temporary situation related to backend system updates, where certain control units require manufacturer assistance for coding. If you're experiencing an Audi control module coding failure, this document outlines the process for dealers to resolve it.

Symptoms

The primary symptom of this issue is the inability to code a replacement control unit after it has been installed in the vehicle. Technicians will observe a "Coding not successful" message during the diagnostic process. The system will specifically indicate that "The coding of the following control module could not be performed: 005F - Information electronics 1", or similar messages for other affected modules.

Affected Control Modules

This TSB applies to specific control units across various 2024 Audi models. If a module not listed below is failing to code, this TSB does not apply, and normal diagnosis should continue. The affected control units are categorized by their diagnostic address and designation:

Diagnosis / Trigger Conditions

The Audi control module coding failure occurs specifically after a control unit has been replaced and the ODIS diagnostic system attempts to run the replacement test plan. The system will display an error indicating that coding could not be performed for the specific module, such as "005F - Information electronics 1". This condition is a direct result of a temporary coding solution implemented by Audi for certain 2024 model year vehicles during updates to their backend systems.

Important Warnings

Audi has issued a crucial notice regarding this TSB:

"During this time, the following control units can only be coded with the help of the manufacturer. If a module NOT listed below is failing to code, this TSB does not apply. Continue with normal diagnosis."

It is also emphasized that proper preparation is key for a successful remote coding session:

"Please read through all content below before proceeding. In an effort to reduce the complexity of the remote coding session, all points below should be strictly adhered to. Lack of preparation will result in delays and possibly re-scheduling of appointment."

Repair Procedure Summary

The repair for this Audi control module coding failure involves a remote coding session assisted by an Audi representative. The general process for technicians is as follows:

1. Preparation: The technician must ensure several prerequisites are met, including having the correct vehicle model and control module, unrestricted internet access for the ODIS tester, the ODIS tester at the latest software level, Microsoft Teams installed, and the Vector Remote Access Point software installed.
2. Email Request: The technician sends an email to [email protected] with specific details including the VIN, affected module address, module availability, and contact information.
3. Scheduling: An Audi representative will contact the dealer to coordinate and schedule a remote coding session via Microsoft Teams.
4. Session Setup: Before the session, the technician must connect a battery maintainer, ensure the new module is installed, hardwire the diagnostic head to the vehicle and ODIS tester, and connect a wired headset with microphone. The ODIS software should NOT be started yet.
5. Remote Coding: During the session, the technician connects to the Microsoft Teams meeting, starts the Vector Remote Access Point, and shares the session ID and password with the Audi representative. The Audi representative then performs the initial coding remotely.
6. Completion: The technician works with the Audi representative throughout the process and completes any subsequent work required after the remote coding session.

Required Tools or Parts

To facilitate the remote coding session, specific tools and software are necessary:

• Microsoft Teams: Software for communication with the Audi representative.
• Vector Remote Access Point: Software (VectorRemoteAccessPoint2.1.3.msi) downloaded from a provided link, used to grant remote access to the ODIS tester.
• Wired headset with microphone: For clear communication during the remote session.
• VAS 6160/VAS 6150: An ODIS tester running the current version of ODIS (Windows 10).

Owner Action

If you own a 2024 Audi model and are informed by your dealership that a replacement control module cannot be coded, your vehicle is likely affected by TSB 00 23 72 2071338/1. The dealership will need to follow the remote coding procedure outlined in this bulletin. This process is typically covered under warranty for qualifying vehicles. Ensure your dealer is aware of this TSB and follows the prescribed steps to resolve the Audi control module coding failure.

Warranty Information

Warranty claims for this procedure are handled under specific conditions:

• Standard Warranty: Up to 48 months or 50,000 miles.
• CPO Covered Vehicles: G10 for Certified Pre-Owned vehicles, requiring owner verification.
• Out of Warranty: If the vehicle is outside of any warranty, this TSB serves as informational guidance only.

Labor operations include module replacement, the coding session (9005 2599, maximum 200 time units), and a road test after the service procedure (0121 0004, 10 time units).

Production Solution

Audi states that this is a temporary coding solution. Once backend system updates are completed, the normal replacement process for control modules will resume, and TSB 00 23 72 2071338/1 will be retired.
