About this Emissions
Service Action

Code Visibility

If Elsa shows other open action(s), inform your customer so that the work can also be completed at
the same time the vehicle is in the workshop for this campaign.

Under this service action, 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 the vehicle is stopped. Emissions still remain within
certification standards.

On or about April 30, 2024, the campaign code was applied to the first wave of affected
vehicles.
On or about August 19, 2024, the campaign code will be applied to the second wave of

Owner Notification

Owner notification for the first wave of affected vehicles took place in May 2024. The second
wave of owners will be mailed in August 2024. Owner letter examples are included in this
bulletin for your reference.

Emissions Campaigns
Requirements
(CALIFORNIA ONLY)

Compliance Label Ordering portal at www.accessaudi.com.
