Customer Letter Example (USA) – WAVE 1 / MAY 2024

This notice applies to your vehicle: ,
Subject: Emissions Service Action 27BQ – Starter - Alternator
Dear Audi Owner,
In cooperation with the United States Environmental Protection Agency and the California Air Resources Board, we are
informing you of our decision to conduct an emissions service action on certain 2019-2020 model year Audi vehicles. Our
records show that you are the owner of a vehicle affected by this action.
About this Emissions Service Action
Under this emissions service action, authorized Audi dealers will replace the starter - alternator in affected vehicles at no cost
to owners. A defective starter-alternator may inhibit start/stop functionality which could increase CO2 and other emissions while
vehicle is stopped. Emissions still remain within certification standards. This work will take about half a day to complete and
will be performed for you free of charge. Please keep in mind that your dealer may need additional time for the preparation of
the work, as well as to accommodate their daily workshop schedule.
What should you do?
In order to limit any possible inconvenience, please contact your authorized Audi dealer as soon as possible to schedule this
work. For your convenience, you can also visit www.audiusa.com and click on the “Find a Dealer” link to locate a dealer near
you and schedule this service.
