How do you fix the fault in the SOS system in an Audi A4 B9?

Model: Audi A4 B9 - Years 2014-2024
Part: Warning light – error code

If the SOS system has a malfunction, it could be caused by a problem with the emergency battery of the telematics module, a software error, or a malfunction of the onboard network. Initially, try restarting the car by turning it off, closing all doors, and waiting a few minutes. If the error persists, it is advisable to perform a software update at a workshop. However, it is often necessary to replace the backup battery, which tends to run out after a few years. The cost is not high, but the intervention of a technician is necessary. If you want to try to solve the problem yourself, check the fuses and connections, but for greater safety it is better to have a check done at an Audi workshop or by a trusted mechanic.
