Symbols Have Different Colors
Much like traffic lights, the color of your dashboard symbol light is just as important as what it means. The lights can also flash to draw your attention to a more severe and time-sensitive issue.
Green
When an Audi’s dashboard warning light is green or blue, this means that one of your car’s features is being used or has been activated. No action is required at this time.
Yellow
When a light is yellow, your car is trying to tell you that a vital safety feature of the car is being used (such as stability control on wet roads), a mild fault has been detected or a repair may be required. If you’re unsure, you should seek the services of a mechanic or dealership as soon as possible.
Orange or Red
If the dashboard on your Audi is orange or red, this can be a signal that your vehicle is experiencing a problem that needs urgent attention. You MUST call or visit your dealership or mechanic immediately.
