Problems with the emergency call system and error codes in the Mercedes B-Class

Hello everyone, I own a 2015 Mercedes B-Class with a diesel engine and 278,700 km on the odometer. I'm currently having problems with the emergency call system not working, and several systems in the vehicle failing. I've also noticed that error codes I've deleted using Carly immediately reappear. Has anyone had similar experiences or can offer any advice on how to fix these problems? Thanks in advance!

Check the vehicle's battery and alternator first, as low voltage can cause multiple system failures and error codes to reappear. Ensure the battery terminals are clean and secure. Let me know if this resolves the issue or if you need further assistance.

The battery was replaced three days ago.

Check the fuses related to the emergency call system and other affected systems. A blown fuse can cause these issues. If the fuses are intact, it might be worth inspecting the wiring for any signs of damage or corrosion. Let me know how it goes or if you have more questions.
