2018-2024 Audi Wiring Harness Repair Documentation TSB

Audi has issued Technical Service Bulletin (TSB) 2061976/3, superseding Group 97 number 21-82, to standardize and improve the documentation process for wiring harness repairs across its 2018-2024 vehicle lineup. This TSB is crucial for ensuring that critical information regarding wiring issues, symptoms, and repair details is clearly recorded. The goal is to enhance the accuracy of warranty claims and provide valuable data for future product design improvements.

Symptoms

Owners of affected Audi vehicles may experience various issues that lead to a wiring diagnosis. Common indicators include:

• "A warning or malfunction is present" on the instrument cluster or infotainment system.
• A wiring issue is identified as the root cause during vehicle diagnosis.

Technical Background

When a wiring issue is diagnosed as the root cause of a vehicle malfunction, technicians often find it challenging to provide clear and comprehensive information. Details describing the specific symptoms, findings, affected circuits, and exact location of damage are frequently unclear in warranty claims. This lack of detail can hinder effective analysis and product improvement efforts.

To address this, Audi is requesting technicians' assistance in meticulously identifying and documenting all wiring repairs. This improved Audi wiring issue documentation will help identify common repair scenarios and inform better product designs.

Repair Documentation Requirements

Proper Audi wiring issue documentation is crucial for accurate diagnosis and warranty claims. Technicians must provide specific details depending on the nature of the wiring issue:

For root causes related to pins or coaxial connector ends:

• Retain approximately 10-20 mm of the original wire, if space allows.
• Repair the connection using the specialized tool VAS1978B.

For root causes related to high resistance or a short circuit in the wiring:

• Overlays may be used during the diagnostic process.
• Retain the affected section of wire that was removed or found faulty.
• Repair faulty sections of the wire using the specialized tool VAS1978B.

Technician notes must include the following details:

• The specific circuit affected.
• Pin identification of the main circuit affected.
• Results of circuit checks, including any resistance and/or voltage values for the affected circuit.
• The precise location where the damaged pin or circuit was found.
• Any other relevant details that support and describe the findings.

Example of detailed documentation:

• "Flexray circuit measured .6 ohm to ground with no components connected to the circuit. Short circuit to ground present on the green FlexRay wire between J743 Dual Clutch T23/1 and J533 Data Bus on Board Diagnostic Interface T54/27. Located damaged wire section underneath the driver seat along the frame rail."

Required Photos for Documentation

To ensure accurate visual records, technicians must take specific photos of the damage and repair area. These photos are to be retained for at least one month after claim approval.

• 1 perspective view: Shows the general area and provides a reference of the surrounding area.
• 1 original routing: Taken before the area of concern is disturbed, showing how the harness was routed in its normal state.
• 1 close-up: Clearly focused and showing the damaged circuit.

All photos should include a date stamp and VIN reference, be in focus, and have sufficient lighting.

Warranty Claim Information

When submitting warranty claims for wire repairs, using the correct PID (Problem Identification) code is essential to differentiate which harness is affected. The following PIDs are provided as examples to help claim repairs in specific locations:

PID	Description	Notes
9709	Central Wiring Harness	For main body harness only. Not for sub-harnesses that are replaceable separately (e.g., door, bumper, or engine harness).
9713	Engine compartment wiring harness	Any repair made to harness sections in the engine bay NOT connected to the main body harness. Claim notes should specify a location.
9732	Door harness	Use for any door. Claim notes should state which door.
9757	Seat harness	Use for any location. Claim notes should specify the location.
9779	Roof wiring harness	Any repairs made to harness sections in the roof. Claim notes should specify a location.
9759	Bumper harness	Use for front or rear. Claim notes should specify the location.
9781	Transmission wiring harness	Any repair made to the harness that is separate from the main body harness and connects to the transmission.

Required Tools and Parts

Technicians will need specific tools to perform and document these wiring harness repairs:

• VAS 1978B: Wiring harness repair set.
• VAS 6160/VAS 6150: VAS tester with the current version of ODIS (Windows 10).
