How to Fix 'SOS Inoperative' Message on Mercedes C-Klasse?

Hello everyone, I own a Mercedes C-Klasse and I'm experiencing a general electrical malfunction. Specifically, I'm getting an 'SOS Inoperative' message on my dashboard. Interestingly, I've tested the SOS system and confirmed that calls can still be made, so the system itself seems to be functioning. My question is: Can the Carly app help in removing this 'SOS Inoperative' message? Any advice or similar experiences would be greatly appreciated. Kind regards, Chris.

Start by checking the vehicle's battery and connections, as a weak battery or poor connection can cause electrical malfunctions. Ensure the battery terminals are clean and tightly connected. If the issue persists, consider using the Carly app to scan for any error codes that might provide more insight. Let me know how it goes or if you have any further questions!
