Why does the Volkswagen dashboard flash at 30km/h?
3 Answers
This is the vehicle's overspeed reminder, which can be freely set between 30km/h and 120km/h, or the reminder can be canceled. Below is relevant information: 1. Function of the speed alarm device: The speed alarm device is an audio alarm system installed in the speedometer to ensure driving safety. If the vehicle's speed reaches or exceeds a certain limit (e.g., 100km/h), the speed switch in the speedometer activates the buzzer circuit, triggering an audible alarm. 2. Dashboard: The dashboard is a rigid panel or structural component used to mount instruments and related devices. It can be categorized by type into screen-type dashboards, frame-type dashboards, passage-type dashboards, and cabinet-type dashboards. Additionally, various indicator lights and warning lights are also located here.
When driving my Volkswagen, I encountered the dashboard flashing at 30 km/h, which is usually the speed limit alert system activating. Volkswagen allows speed reminders to be set in certain models, such as flashing a light at 30 km/h to prompt you to slow down. It's possible the owner unintentionally set this value, or the system automatically triggered the warning in wet weather. The solution is simple: use the steering wheel buttons to enter the dashboard settings menu, find the speed alert option, and turn it off or reset it. If the flashing occurs frequently, check tire pressure or sensor faults to avoid safety issues. Address it promptly to prevent bigger problems and develop a habit of regularly reviewing vehicle settings.
As a technical enthusiast who has worked on many cars, the flashing 30 km/h indicator on Volkswagen dashboards usually points to the programmable speed alarm function. Designed to remind you not to speed in urban areas or near schools, this warning may be triggered by abnormal output signals from the speed sensor. Troubleshooting method: Connect a diagnostic tool to read fault codes and check if the sensor connector is loose or if there's wiring corrosion. For routine maintenance, it's recommended to clean dust from the dashboard area monthly to prevent accidental triggers. If the flashing is accompanied by other warning lights, consider potential issues with the ABS or ESP systems, which require professional inspection.
