Why does the engine of my Audi show a warning light?

I recently noticed a warning light on the dashboard of my Audi. It looks like a car with an exclamation mark inside. What could be causing this and how should I address it?

The warning light may indicate a range of issues, from a simple maintenance reminder to a serious problem with your engine. The best course of action would be to consult your owner's manual for specific guidance based on your Audi's model and year. If the light persists or is accompanied by strange noises or smells, it's best to take your car to a certified mechanic for a diagnostic check.

Sometimes, the warning light may come on due to something as simple as a loose gas cap. Try tightening the cap and seeing if the light goes away. If not, you can purchase a OBD-II code reader to plug into your car's diagnostic port to retrieve the specific error code. Alternatively, you can take your car to a dealership or auto shop that has professional diagnostic equipment.
