Brake Pad warning light?
 

I have a 2008 A4 2.0T. I've been told that my brake pads/rotors need to be replaced. I've also been told that a warning light will appear if/when the pads get really worn. Is this the case? Does anyone have a pic of what this looks like?

Thanks!

The front pads have sensors, the rears don't.

Look in your manual, It will show you what the symbol looks like. It looks like a drum brake if I remember right, and pops up on the display between the tach and speedo.
