Volkswagen SOS emergency call function malfunction solution: It is necessary to go to a maintenance organization to check the fault code storage, and eliminate it after inspection and repair. Emergency call function role: The main role of the SOS emergency call system is to provide emergency rescue services based on user feedback when the vehicle is in an emergency situation. Emergency call function usage: When the vehicle malfunctions or is involved in an accident, or when encountering danger and facing an emergency situation, find the SOS button and hold it for more than 2 seconds. The vehicle's emergency warning and rescue system will automatically send out a distress signal and actively call the emergency department.

Last time my Lavida also had an emergency call function failure, and I followed the steps in the manual to troubleshoot step by step. First, I checked if the emergency call was enabled in the system settings, ensured the SIM card was inserted correctly and had no overdue payments, and also checked if the roof antenna was obstructed. Then, I inspected the in-car fuse box, located the fuse marked for emergency calls, and confirmed it wasn’t blown. If none of these issues were found, I recommend going directly to the 4S shop to use a diagnostic computer to check the system module. I spent half an hour trying to fix it myself without success, but the 4S shop resolved it by upgrading the software program. During regular maintenance, you can ask the technician to check if this function is working properly as a preventive measure.

As a Lavida owner who has experienced three emergency call failures, I'd like to share my experience. First, try holding the SOS button for 10 seconds to force restart the system, which can resolve most temporary freezes. Then open the glove box and check if the data cable connection is loose. Most importantly, test the signal strength at your vehicle's location - underground parking or remote areas often have no signal causing function failure. Last week my infotainment system automatically updated and the function was restored, so I recommend regularly connecting to Volkswagen's official server to check for updates. If these methods don't work, it's likely a host module failure requiring part replacement, costing around two thousand yuan.

The emergency call malfunction in Lavida is typically diagnosed from three aspects: physical connections, software systems, and external factors. For physical issues, first check if the button contacts are stuck—cleaning is required if there's noticeable resistance when pressing. Next, access the central control system and verify in the vehicle settings whether the service subscription has expired, as many owners are unaware this feature requires paid renewal. On the software side, restoring factory settings to reset the communication module is recommended. External factors mainly refer to network service provider issues, where differences in China Mobile and China Unicom signal coverage can directly affect functionality stability. If simple troubleshooting fails, always use a professional diagnostic tool to read fault codes for precise problem identification.
