What the Brake Pad Wear Light Means on a Audi Q8 e-tron

The exact reason can vary from something as minor as a loose connection to a component that needs replacing, which is why reading the stored trouble codes is the reliable way to know for certain.
Can I keep driving with the Brake Pad Wear Light on?
