If you’re experiencing brake issues and see the warning light, it’s important to address it promptly. There are several reasons why your Audi A4 might display this warning, ranging from simple fixes to more complex problems. It could be something as straightforward as low brake fluid or worn brake pads, or it could indicate a more serious issue with the braking system. Don’t delay getting this checked.
One common culprit is worn brake pads. Your Audi A4 is equipped with a sensor that monitors brake pad thickness. When the pads wear down to a certain level, the sensor triggers the warning light. Ignoring this warning can lead to further damage, potentially requiring costly repairs. Regular brake inspections can help you avoid this.

This should be addressed immediately, as driving with low brake fluid can compromise your safety. Check the brake fluid reservoir and top it off if necessary, but be sure to use the correct type of fluid specified in your owner’s manual.
