C5 2000 2.7T 187,000 miles 6 speed on stock K03's

Hey guys,
So i was driving normal other day with no issues until, i notice that i get a yellow light on the dash I've never seen before. It's in the same spot as if you were low on fuel and the fuel light came on. Looks exactly like this: "O"
Not sure what it means but if there's any directory or resource anyone can point me to, that would be greatly appreciated. Thanks!!!

 

I will suggest get a code reading from parts store like autozone its free.

 

Look like this? If so, it's your brake pad warning light.

 

Yeah it looks very similar, I'm assuming it's the same warning light. You just have the nicer car! Thanks guys!

 

Only the front brakes have the sensor. Make sure you check the rear brakes, too. BTW, that little circle is a representation of you grabbing your face and screaming when your brakes fail at 70 mph.

 

I thought that was a picture of something you have to bend over and present to the Audi dealer to fix your brakes
