The issue shown by the YouTuber refers to the malfunction of the SOS/Emergency call system on Audi vehicles, which manifests with a persistent error message "Emergency call function not available. Please call for assistance" and an additional message on the MMI screen "Data connection could not be established.

Check network coverage" even when in a covered area. This is accompanied by an annoying "beep" that continues even when the message disappears, and the microphone functionality during calls is interrupted (the user can hear but is not heard).

Other functionalities also stop working. The user's attempts to reset (MMI reset, holding the SOS button, leaving the car off overnight) have not worked.

The problem is often caused by a dead auxiliary battery; checking the status of the main battery can also help, as the system is very sensitive. Next, attempt a deep reset by disconnecting the battery terminals for at least 30 minutes (but you will lose many settings that will need to be re-entered).

Check the "telematics" or "eCall" fuse. Sometimes a firmware update is necessary, or the antenna may be damaged: in these cases, a visit to the dealer is required.
