Audi EV charger intermittently loses connection to the Audi backend or app, but local charging continues.

Safety first: No high-voltage work is required; this is a network issue.

• Check internet connection: Verify that other devices on the same network have stable internet access.
• Router configuration: Ensure that required ports and outbound connections for the Audi backend are not blocked by firewall settings.
• Firmware update: Update the charger’s communication module firmware via the app or service interface.
• Switch network medium: If using Wi-Fi, consider switching to wired Ethernet if the charger supports it, or vice versa, to isolate the issue.

If backend connectivity remains unstable despite a solid local network, Audi support may need to check server-side logs, and the communication module may require replacement.
