2021-2024 Audi Technical Analysis List for Various Issues

This Audi On-Car Analysis List, dated July 15, 2024, provides important guidance for technicians addressing a range of common issues across various Audi models from 2021 to 2024. The document outlines specific symptoms, affected vehicles, and initial diagnostic steps or warnings. It covers concerns from airbag warning lights, such as when your Audi airbag light B101704 appears, to infotainment system glitches and mechanical noises.

Important Warnings and Owner Information

Audi emphasizes that technicians should contact the Audi Helpline before attempting any repair related to these topics. As of June 7, 2024, worksheets are no longer a standard practice and are only required if explicitly listed in the topic details.

For issues involving the airbag system, specific warnings are provided:

• Do not perform GFF test plan.
• Do not erase DTC.
• For DTC B12251B, Do Not perform GFF or test plans for this DTC.
• For DTC B12251B, Do Not perform any repairs or disconnect the PODS sensor mat or PODS control module.

These instructions are crucial to prevent incorrect diagnosis or accidental deployment of safety systems.

Common Symptoms and Affected Models (2021-2024 Audi)

This analysis list covers several distinct issues affecting different Audi models and model years within the 2021-2024 range:

Airbag System Warnings

• Airbag light on, DTCs B101704, B103604: This issue affects 2021-2024 Audi Q5 models. When your Audi airbag light B101704 or B103604 illuminates, it indicates a fault within the supplemental restraint system. Technicians are directed to TSB 2073566 and specific worksheets for instructions.
• Q5 Airbag light, DTCs B101C13, B101D13: This specific airbag light issue is noted for 2024 Audi Q5 vehicles. Similar to other airbag faults, technicians are advised to consult worksheets and avoid certain diagnostic procedures.
• Airbag light B12251B: This fault specifically impacts 2023-2024 Audi Q7 models. If the DTC B12251B is stored in the airbag control module, J234 (da0015), technicians must contact TAC (Technical Assistance Center) for guidance.

MIB3 Infotainment System Issues

• MIB3 - Stuck on "loading user information": This problem affects 2024 Audi A3 and Q3 models. Owners may experience the screen being stuck on the "loading user information" screen during bootup, with no user interaction possible, though the backup camera may function normally. If these criteria are met, technicians should contact TAC for potential data logger installation.

Mechanical and Noise-Related Concerns

• Roof panel buttons inoperative: This affects 2022-2024 Audi Q4 e-tron vehicles. Symptoms include unresponsive dome light buttons or sunroof buttons, typically occurring together. Further instructions are available in a dedicated worksheet.
• Front door(s) hard to close: This condition is noted for 2024 Audi Q5 models, often described by customers as "Q5 Front door high closing effort." Before any repairs, technicians must measure the door dimensions as outlined in the associated worksheet.
• Front windows noisy and/or binding: This issue impacts 2023-2024 Audi A4, S4, and A4 allroad models. Before repairs, a video of the customer's complaint is required. After identifying the root cause (e.g., window regulator, window guide, slot seals), another video of the causal part or the resolved operation is needed.
• Front door wind noise: This is a concern for 2023-2024 Audi Q7 models, particularly noticeable at highway speeds. Technicians need to detail their findings to identify the source of the noise, referring to a worksheet for further details.

Diagnosis and Initial Guidance

For most issues, the document emphasizes consulting specific worksheets or contacting Audi's Technical Assistance Center (TAC) for detailed instructions. This approach ensures that complex diagnostics and repairs are handled correctly, especially for safety-critical systems like airbags.

For the MIB3 "loading user information" issue, data logger installation might be required, indicating a need for in-depth system analysis. The guidance for window and door issues highlights the importance of thorough documentation, including video evidence, before proceeding with repairs. This helps in accurately identifying the root cause and verifying the effectiveness of the repair.

What Owners Should Do

If you experience any of these symptoms, such as your Audi airbag light B101704 illuminating, or issues with your MIB3 system, it is recommended to contact your authorized Audi service center. Provide them with a clear description of the problem, including any warning messages or specific conditions under which the issue occurs. Your service center will have access to the latest technical information and specialized tools to diagnose and resolve these concerns according to Audi's guidelines.
