Audi SOS Malfunction? Quick Fix & Easy Reset Guide You Can Try Today

If your Audi displays an “SOS Malfunction” warning on the dashboard, it means the vehicle’s emergency call system has detected an issue that needs attention. Fortunately, in many cases, you can fix or reset it without visiting the dealership. Here’s a detailed step-by-step guide to help you resolve the problem safely and effectively.

Start with a basic system restart. Turn off your Audi completely, remove the key (or turn off the ignition for push-start models), and wait at least five minutes. This allows the control units to power down fully. Then restart the car and check if the SOS warning disappears. Sometimes, temporary software glitches cause the alert, and a restart clears it instantly.

If the warning remains, try a soft MMI system reset. Press and hold the power button on your MMI control knob or screen (depending on model) for about 10 seconds until the display turns off and restarts. Once the MMI reboots, give it a moment to reconnect to the car’s internal systems. This often resolves temporary connection issues between the emergency call module and the infotainment system.

Next, check the cellular connection. The Audi SOS system uses an embedded SIM card to connect with Audi’s emergency call network. If your car has poor signal reception—especially in underground parking lots or remote areas—the system might temporarily lose connection and trigger a malfunction warning. Drive to an open area with strong network coverage, restart the car, and see if the issue clears.

If you still see the message, check the fuse and power supply related to the emergency call module. A weak or disconnected 12V battery can interrupt communication between modules. Ensure your main battery is healthy and fully charged. If you recently replaced or disconnected the battery, reset the vehicle’s electrical system by locking the car, waiting 10–15 minutes, and unlocking it again.

In some models, the SOS warning may appear after software updates or telematics module errors. You can manually reset the telematics control unit. Disconnect the negative battery terminal for about 10 minutes, then reconnect it. This forces the control unit to reboot and re-establish a connection with the Audi network. Remember to have your radio and MMI settings backed up before disconnecting the battery.

If none of these steps work, use the Audi connect settings in the MMI menu to check for system updates. Go to Settings → Connection → Online Services → SOS Functionality. Make sure the feature is enabled and the system status shows “Active.” If it’s disabled or unregistered, reactivate it using your Audi connect account or through your local Audi service center.

For owners comfortable with using diagnostic tools, you can scan for fault codes using an OBD-II scanner or VCDS software. Look for telematics-related codes such as “B201A” (control unit not coded) or “U0197” (lost communication with telephone control module). Clearing these codes after performing the reset often removes the warning message.

To prevent future issues, keep your Audi software updated, ensure stable battery voltage, and avoid disconnecting electrical components unnecessarily. Regularly check your MMI system and Audi connect status during service visits.

By following these steps, you can often clear the Audi SOS malfunction message quickly and restore full functionality to your car’s emergency call system without a costly dealership visit.
