2022-2023 Audi e-tron GT Wiring Harness Restriction TSB

Audi has released Technical Service Bulletin (TSB) 97HJ UPDATE to proactively prevent a condition affecting the wiring harness in the rear lid hinge area of certain 2022-2023 Audi e-tron GT and RS e-tron GT vehicles. This TSB, titled "Retrofitting Cable Holder – (NVLW)", aims to resolve the potential for restricted movement of the wiring harness, which could lead to future electrical issues.

This update was originally published on October 24, 2023. The 97HJ UPDATE is a proactive measure to ensure the long-term reliability of the vehicle's electrical system.

Symptoms

This TSB is a proactive update designed to prevent a condition from occurring, rather than addressing an existing symptom. The core issue is the restricted movement of the wiring harness in the area of the rear lid hinge. Owners would not typically observe a direct symptom related to this restriction until a potential failure occurs. The update aims to prevent such failures.

Diagnosis / Trigger Conditions

To determine if your 2022-2023 Audi e-tron GT or RS e-tron GT is affected by this 97HJ UPDATE, an authorized Audi dealer must check the Elsa Campaign/Action Information screen. Your vehicle must show the 97HJ code as "open" on the day of repair to be eligible for this procedure. The vehicle must also be within its New Vehicle Limited Warranty period.

Important Warnings and Owner Information

• This Update is currently in effect and will remain so until Audi removes it.
• The Elsa system is the only valid source for verifying vehicle eligibility. Always ensure the 97HJ code shows as "open" in Elsa on the day of service.
• If the update appears to have been performed but the 97HJ code is still open in Elsa, the dealer must contact Warranty before proceeding.
• Any open Safety Recalls must be completed before this campaign can be performed.
• Dealers are instructed not to claim for vehicle wash or loaner services under this action.
• During the repair, technicians are warned about the risk of airbag deployment and injury. If the airbag indicator lamp is on or flashing, the DTC memory must be read. If a "short circuit to positive" DTC is present, the battery must be disconnected. Guided Fault Finding instructions must be followed if any DTCs are present. If no airbag lamp is on, the ignition must be switched off, and all vehicle keys and start authorization systems (like smartphones) must be kept away from the vehicle for at least 10 seconds.
• Technicians must discharge static electricity by touching the door striker to prevent unintentional deployment of pyrotechnic components.
• Caution is advised during trim panel removal to prevent consequential damage; specific prying techniques are recommended.
• If any wiring damage is found during the procedure, repairs must be made according to the ELSA repair manual, using highly flexible wires in non-moving areas to prevent repeat repairs.

Repair Procedure Summary

The repair for the Audi e-tron GT wiring harness restriction involves several steps to modify the cable routing and install a new cable holder. The procedure is performed on both the left (driver) and right (passenger) rear lid hinges.

1. Vehicle Preparation: The technician first verifies the vehicle's eligibility using the Elsa system and confirms the 97HJ code is active. Any outstanding safety recalls must be completed prior to starting this update.
2. Accessing the Harness: This involves carefully removing the luggage compartment side trim panels and the rear lid hinge trim covers. Specific safety precautions are outlined due to the presence of airbags and pyrotechnic components in these areas.
3. Harness Modification: The existing retaining clips and cable ties are released and removed from the harness. The original cable holder is disengaged. The harness is then marked, and a section is unwrapped. The technician inspects the harness for any damaged wires or cables and performs necessary repairs according to the ELSA manual, using highly flexible wires if replacements are needed.
4. Installing New Components: A new protective sleeve (Part Number 4J3-971-889) is installed over the harness and secured with adhesive tape (Part Number N-105-436-02). The cable holder is then refitted, ensuring proper alignment with the previously made mark on the harness. New cable ties (Part Number N-106-232-01) are installed, and the cable holder outlet is wrapped with three layers of adhesive tape.
5. Cable Guide Installation: A new cable guide (Part Numbers 4J3-971-848 for the right side, 4J3-971-849 for the left side) is installed into the rear lid hinge, making sure the harness is correctly positioned within the guide. The harness is then secured with another new cable tie (Part Number N-909-377-01).
6. Reassembly: All removed components are reassembled in reverse order. Specific torque values are provided for the luggage compartment tie-down bolts (20 Nm) and side cushion cover bolts (10 Nm) to ensure proper reinstallation.
