Service bulletin A001458 2026692-

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Supersedes Technical Service Bulletin Group 00 number 12-43 dated December 21, 2012. 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. These procedures are mandatory until further notice. Warranty repairs without repair authorization via a TAC contact will not be reimbursed.
