Display problems of new Jetta water thermometer

1. First of all, the water temperature display of the new Jetta can't be as high as 90, which is usually a normal water temperature value. 2. Your vehicle has been used for more than one year, and the normal water temperature shows 90, indicating that your vehicle water circulation system is working normally, the water tank and water pipe are free of dirt and blockage, and the thermostat and electronic exhaust fan are working normally; 3. When it is turned on, the water temperature alarm light will give an alarm prompt at the first time.
