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.
