Why does my Audi A1 display a low fuel warning light even though it has enough fuel?

I recently noticed that my Audi A1 displays a low fuel warning light even though the fuel gauge shows that there is still enough fuel in the tank. What could be causing this issue and how can I fix it?

The low fuel warning light is triggered by a sensor in your fuel tank that measures the amount of fuel present. It is possible that the sensor is malfunctioning, causing it to display the warning light even though there is enough fuel in the tank. It is recommended to have this sensor checked and possibly replaced by a mechanic.
