action. Elsa is the only valid campaign inquiry & verification source.

About this Service
Action



Campaign status must show “open.”



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.

Some customers have reported unexpected reboots of the infotainment system.
After a thorough investigation, Audi has determined this change originated outside of Audi and
that the issue was triggered by a broadcast change made by SiriusXM, which interacts with the
infotainment software in a way that was not anticipated in the original system design.
Audi is providing a software update to correct the infotainment system behavior and prevent
further reboots. This software delivers enhanced system robustness, multiple bug fixes, and
additional performance improvements.
SiriusXM implemented a temporary broadcast adjustment to help stabilize system performance
while updates are being applied.

The repair information in this document is intended for use only by skilled technicians who have the proper tools, equipment and training to correctly and safely maintain your vehicle. These
procedures are not intended to be attempted by “do-it-yourselfers,” and you should not assume this document applies to your vehicle, or that your vehicle has the condition described. To
determine whether this information applies, contact an authorized Audi dealer. 2025 Audi of America, Inc. and Audi Canada. All Rights Reserved.
