Original Publication

If a 2012 - 2015 Audi A8 L W12 arrives at an Audi dealership and requires diagnosis or repair, a Repair
Authorization must be obtained.
Prior to any repair, a Technical Assistance Center (TAC) ticket must be created for engine and transmission
concerns only. Routine maintenance and PDI do not require prior authorization or a Technical Assistance Center
(TAC) ticket. For all other concerns:
• These procedures are mandatory until further notice.
• Warranty repairs without repair authorization via a TAC contact will not be reimbursed.

Technical Service Bulletin
Service
The following procedure should be followed by all Audi technicians for all vehicle issues (excluding routine
maintenance, PDI, or repairs for which a TSB applies).
1. Verify customer concern.
2. Begin GFF diagnosis. Do not remove any part or disconnect electrical connectors until instructed to do so.
3. Create a ticket using the TAC system in Elsa.
4. Select A8 L W12 Engine & Transmission only Repair Authorization in the Concern Type field for proper
routing to our launch-dedicated TAC Consultant, as shown below.

5. Describe the customer concern with as much detail as possible. Fill in all required fields.
6. Please include your cell phone number in the TAC ticket. The TAC consultant will use this number to contact
you so you can be near the car during the conversation.
7. Always attach the Collection Services Diagnosis Log and photos that illustrate the concern.
8. Activate the TAC ticket promptly by calling the Technical Assistance Center for further instruction before
carrying out any repairs.
The Repair Authorization and repair plan will be communicated via the TAC dedicated consultant within an hour of
receiving the technician’s call. This will ensure that the correct information is gathered so that any issues found
can be properly repaired and improved in production. If there is no response within the hour, the technician may
proceed with the repair. In the event the Technical Assistance Center System is down, the technician may call the
Technical Assistance Center for assistance; however, a TAC Ticket must still be submitted to validate the warranty
claim.
