What is the issue with the Volkswagen Passat's emergency call malfunction?
2 Answers
When using the vehicle, the SOS emergency call yellow light on the dashboard will illuminate, indicating a system malfunction that requires inspection and repair at a maintenance facility. Emergency Call Button: The vehicle's SOS button is usually located near the sunroof controls on the ceiling, typically red and labeled with the letters SOS. The onboard SOS system generally includes the SOS button, an emergency horn, a microphone, and an antenna. Purpose of Emergency Call: Cars have long been equipped with SOS onboard systems. SOS stands for the onboard self-rescue system. When the vehicle experiences a malfunction or accident, or when facing dangerous and sudden situations, pressing and holding the SOS button for more than 2 seconds will automatically send a distress signal, actively calling emergency services. Occupants in the vehicle can communicate via the emergency microphone. During emergencies, the SOS emergency call can provide emergency rescue services based on user feedback, offering convenience and peace of mind.
The emergency call system in the Volkswagen Passat may malfunction due to software issues or hardware aging. The system relies on the onboard computer and GPS module, and sometimes incorrect program updates can cause it to fail, or poor antenna signal reception can prevent it from connecting to the network for help. On the hardware side, if the main control module is damaged or a fuse blows, the entire system loses power. Unstable battery voltage is also a contributing factor, especially after prolonged parking. Additionally, if the vehicle has been in a collision but the damage isn't obvious, sensors may give false alarms or freeze. My personal advice is not to ignore this issue, as it can automatically alert authorities in an accident, protecting your safety. It's best to have a technician scan for error codes with diagnostic tools during maintenance and replace faulty components promptly. Also, environmental factors like weak signals in tunnels or underground garages can cause temporary failures, but if the problem persists, it should be repaired immediately. In short, this issue relates to driving safety—don't cut corners to save money; getting it fixed at an authorized repair shop is the most reliable solution.
