2021-2024 Audi e-tron Charging Cable and Other Issues

Audi has released an On-car analysis list, dated May 3, 2024, outlining various common issues and diagnostic procedures for a range of its vehicles. This document serves as a guide for technicians to address specific customer complaints, including problems with the Audi e-tron charging cable, airbag warning lights, and other mechanical or electrical faults. Owners experiencing these symptoms should be aware of the recommended steps and warnings provided by the manufacturer.

Important Warnings for Owners and Technicians

This analysis list contains critical instructions that must be followed to ensure proper diagnosis and avoid unnecessary repairs or damage. For several issues, specific diagnostic steps are prohibited:

• Do not perform GFF test plan: This warning applies to issues like "Q5 G31 no com" (DTC U060B00) and certain "Airbag light on" DTCs (B101704, B103604, B101C13, B101D13).
• Do not erase DTC: For the same issues mentioned above, technicians are explicitly instructed not to clear the Diagnostic Trouble Codes.
• Do Not perform any repairs or disconnect the PODS sensor mat or PODS control module: This strict warning is issued for the "Airbag light B12251B" issue affecting 2023-2024 Audi Q7 models. Repairs or disconnections should only occur after contacting the Audi Technical Assistance Center (TAC).

Common Symptoms and Faults

This analysis list covers a variety of issues reported across different Audi models and model years, from 2017 to 2024. These symptoms can range from charging system malfunctions to interior component failures and fluid leaks.

Charging System Malfunctions

For 2022-2024 Audi Q4 e-tron models, a common complaint is that the "Charging cable cannot be removed." Similarly, 2019-2024 e-tron Q, SB, and Q8 e-tron models may experience the "Vehicle cannot be charged, charge socket lock without function." Both scenarios require technicians to complete an e-tron charging questionnaire worksheet for diagnosis.

Airbag System Alerts

Several airbag-related issues are noted. For 2021-2024 Audi A6, A7, A8, e-tron, Q5, Q7, and Q8 (all variants), an "Airbag light on" may appear, often accompanied by Diagnostic Trouble Codes (DTCs) B101704 and B103604. For these specific DTCs, technicians are directed to TSB 2073566 and a dedicated worksheet for instructions. A distinct issue for 2023-2024 Audi Q7 models involves an "Airbag light B12251B." If this DTC is stored in the airbag control module, J234 (da0015), the Audi TAC must be contacted immediately.

Electrical and Communication Issues

• Q5 G31 no com: For 2022-2024 Audi Q5 models, this indicates a communication issue with the G31 component, often accompanied by DTC U060B00. Technicians must inspect harness routing, supply photos of findings to the TAC, and refer to a specific worksheet.
• Roof panel buttons inoperative: Affecting 2022-2024 Audi Q4 e-tron and 2024 Audi Q5/SQ5 models, this issue manifests as unresponsive dome light buttons or sunroof buttons, which may also come on without input. Technicians are required to perform worksheet steps and report findings to TAC.

Mechanical Concerns

• Corrosion on wheelhouse cover plate: This issue affects 2017-2019 Audi Q7 and 2019 Q8 models. Diagnosis involves various photos and inspections, with technicians consulting a specific worksheet.
• Oil leaking from cylinder head cover bolts: For 2020-2024 Audi Q5 models, this applies only if no previous repairs involved removing the cylinder head bolts. Technicians must provide detailed photos showing the leaking bolts.
• Front door(s) hard to close: This problem is noted for 2024 Audi Q5 (all variants). Before any repairs, technicians must measure the door dimensions as outlined in the "Checklist door dimensions" table and submit a TAC case with the "Q5 Front door high closing effort" worksheet.
• Front door wind noise: For 2023-2024 Audi Q7 and SQ7 models, this refers to wind noise from the front door at highway speeds. Technicians need to detail findings regarding the source of the noise and refer to a worksheet for further details.

Diagnostic and Repair Guidance

For many of these issues, Audi emphasizes the use of specific worksheets and direct communication with the Technical Assistance Center (TAC). These worksheets provide detailed, step-by-step instructions for diagnosis and data collection, ensuring that technicians gather all necessary information before attempting repairs. For instance, the Audi e-tron charging cable issues require a dedicated questionnaire.

In cases like the "Q5 G31 no com" (DTC U060B00) and certain airbag light DTCs, technicians are instructed to inspect harness routing and supply photos of their findings to the TAC. This collaborative approach helps Audi engineers understand the root cause of complex issues.
