Warning light on audi a4

https://www.justanswer.com/audi/1qbl7-warning-light-showing-yellow-circle-triangle.html

Yellow circle, with triangle and exclamation mark – The Electronic Stability Program (ESP) dashboard light flashes if the ESP or traction control is activated whilst driving. If ESP or traction control has been switched off, it will light up continuously. If ESP or traction control is not turned off and the warning light illuminates continuously, it indicates a problem and malfunction with either ESP or traction control.

Hmm... Does your Audi have the old version of the Tire Pressure Monitoring System? (I am guessing because it sounds VERY much like the 'icon' display that GM uses for warning the driver that tire pressure is low (or too high). Otherwise, ignore me...

It's an yellow warning indicator lamp. It lights when brake pads are weared. Now it's time to replace the used brake pads!

try to reset it by usng obd2 then drive your car for 20 to 30 miles if the lights came on again try to go to nearest autozone and check the ecm code and replace the defects ...god bless

If it's an orange circle with broken parentheses on each side it would be your brake pad wear warning light. You should have your brake pads inspected.

It indicates you have a problem with your brakes. Get it checked out soon!

look like it's your brake warning light, have some one check your brake pads, brake fluid and parking brakes

hazard light problem

sounds like a traction control light
