2023-2024 Audi Infotainment and Connect Damage Codes TSB

Audi has released Technical Service Bulletin (TSB) 91 23 71 2068171/4, dated February 7, 2023, to provide updated warranty submission instructions for infotainment and Audi connect concerns in 2023-2024 Audi vehicles. This TSB supersedes bulletin 91 23-57 dated January 3, 2023, for reasons related to the expansion of damage codes. The primary purpose of this document is to introduce new, more specific damage codes for technicians to use when invoicing warranty claims related to the infotainment system and Audi connect, addressing issues like an "MMI not starting, welcome screen" or an "Emergency call button LED is not green". This update helps ensure accurate documentation of various Audi e-tron infotainment damage codes and related issues.

Important Warnings for Technicians and Owners

This TSB explicitly states: "This TSB does not contain any repair instructions. It provides information on new damage codes related to the infotainment system and Audi connect, which should be used from MY23 onwards." Therefore, this document serves as a reference for warranty coding, not a guide for diagnosing or repairing issues. Technicians are advised: "Please use these new damage codes when invoicing the concerns described in the 'Warranty accounting instructions' section." This ensures proper billing and tracking of issues, including those affecting the Audi e-tron infotainment damage codes.

Technical Background for Infotainment and Audi Connect Damage Codes

Previously used damage codes, such as 0039 and 0040, for infotainment and Audi connect functions were often insufficient to precisely describe the root cause or conditions of a customer's concern. Audi has expanded its existing damage code system to allow for more specific invoicing. This means that when a customer reports an issue, such as an "MMI not starting, welcome screen" or a "myAudi login error", technicians can now use more precise codes to document the problem for warranty purposes. This enhancement improves the clarity of warranty claims for issues like Audi e-tron infotainment damage codes.

Understanding Service Numbers and Components

The TSB outlines specific service numbers associated with various infotainment and Audi connect components, along with their diagnostic addresses and system designations:

• Service Number 9170: Refers to the Telematics control unit, found at diagnostic address 0075. This unit includes OCU3 or OCU4 and is applicable to Audi A3, Q3, and Q4 models (including S and RS versions). In the diagnostic log, its system designation typically includes "OCU...".
• Service Number 9145: Pertains to the Transmitter and receiver unit, also at diagnostic address 0075. This covers the Connectivity box Low or Connectivity box High (ConBox) for models such as the Audi A4, A5, Q5, A6, A7, Q7, A8, Q8, e-tron, and e-tron GT (including S and RS versions). Its system designation in the diagnostic log will show "ConBox" or "CB_H_".
• Service Number 9196: Designates the Control unit for display and operating unit.
• Service Number 9107: Relates to Information electronics (MMI) at diagnostic address 005F, applicable to all models. This also covers "Online services," which includes Audi connect systems or components external to the vehicle, such as mobile network providers or backend servers.
• Service Number 9103: Identifies the Rear MMI control panel, specifically the Rear seat wireless control head (SCON) for Audi A8 models.
• Service Number 9193: Used for the Touch screen display unit, which includes the Front MMI touch-screen display (both single and dual displays).
• Service Number 9194: Refers to the Display unit, covering the Front MMI display (non touch-screen).

New Damage Codes and Their Meanings

New damage codes have been created to provide more specific descriptions for various customer concerns related to the infotainment system and Audi connect. These codes are crucial for accurately categorizing issues like an "Online map update error" or a "display flickers/distorted" screen.

Damage Code	Description
A039	"Emergency call button LED is not green (SOS is Red)"
A139	"myAudi login error (Customer cannot log into myAudi in MMI)"
A239	"screen off, sound is working"
A339	"Online map update not available"
A439	"Online map update error"
A539	"MMI not starting, welcome screen"
A639	"display flickers/distorted"
A739	"Touch display responds without any contact being made"
A839	"Navigation destination deleted/missing"
A939	"display blue"

Detailed Scenarios: Service Number and Damage Code Combinations

The TSB provides detailed combinations of service numbers and damage codes, along with explanations of the cause. This helps technicians accurately identify the root cause of issues, including those related to the Audi e-tron infotainment damage codes.

• Emergency Call LED Not Green (A039): This concern can be attributed to several factors. If it's due to an issue not caused by vehicle technology, service number 9107 is used. If the emergency call module (ConBox or CB_H_) is the cause in models like A4, A5, Q5, A6, A7, Q7, A8, Q8, e-tron, and e-tron GT, use 9145. For A3, Q3, and Q4 models where the OCU emergency call module is at fault, service number 9170 applies.
• myAudi Login Error (A139): If the "myAudi login in the vehicle does not work" due to an issue not caused by vehicle hardware, service number 9107 is appropriate. However, if the information electronics control unit (diagnostic address 005F) is the cause, service number 9196 is used.
• Screen Off, Sound Working (A239): When "Nothing is shown on the screen, but the sound output is working," the cause varies. For rear display issues, service number 9103 is used. A faulty front touch display points to 9193, while a faulty front display (non-touch) uses 9194. If the information electronics (diagnostic address 005F) is the root cause, service number 9196 applies.
• Online Map Update Issues (A339, A439): If "No online map update is offered in the vehicle" or "An online map update was started but is canceled or shows an error message" due to a non-vehicle technology issue, use 9107. If the information electronics (diagnostic address 005F) is the cause, service number 9196 is used for both scenarios.
• MMI Stuck on Welcome Screen (A539): If "The MMI gets stuck on the welcome screen after it is switched on," and the emergency call module (OCU) is the cause, use service number 9170. If the information electronics (diagnostic address 005F) is the issue, use 9196.
• Display Flickers/Distorted (A639): A "display flickers/distorted" screen caused by a faulty front touch display uses service number 9193. If the information electronics (diagnostic address 005F) is the cause, use 9196.
• Navigation Destination Deletes Itself (A739, A839): If "A stored navigation destination, the most recent destinations or the home address deletes itself" due to a faulty front touch display, service number 9193 applies. If it's an issue not caused by vehicle technology, use 9107. If the information electronics (diagnostic address 005F) is the cause, use 9196.
• Blue Screen Display (A939): For a "screen is blue on one or both front displays," a faulty front touch display points to 9193. A faulty front display (non-touch) uses 9194. If the information electronics (diagnostic address 005F) is the cause, use 9196.

Warranty Claim Procedures and Labor Operations

This TSB provides critical guidance for technicians on how to correctly submit warranty claims. Service number 9107 is specifically for technical issues not caused by the vehicle itself, such as problems with the mobile network or backend server, and should not be used for invoicing part replacements. Work performed on the vehicle due to external issues must be invoiced using service number 9107, rather than the service number for the component involved in the repair. Conversely, service numbers for specific control units (e.g., 9145, 9170, or 9196) should only be used if that component was definitively identified as the root cause of the customer concern and potentially replaced.

For identifying labor operation codes not found in Elsa, technicians are directed to reference Audi Warranty Policies and Procedures Bulletin "AWA 22-15," released November 23, 2022. This bulletin is accessible via the Audi Warranty Online portal through iAudi/AccessAudi (App Links >> Service >> Audi Warranty Online >> Search “AWA 22-15”).

An example provided in the TSB illustrates the claim process:
