What the Brake Pad Wear Light Means on a Audi A4 Allroad
On the Audi A4 Allroad, this symbol indicates worn brake pads. A sensor in the pad has reached the wear limit, telling you replacement is due before braking is compromised.
How Urgent Is the Brake Pad Wear Light?
Urgency level for this indicator on the Audi A4 Allroad: moderate.

Green and blue symbols are simply telling you a system is active. Whatever the colour, the safest habit is to note when the Brake Pad Wear Light appeared, how the Audi A4 Allroad is behaving, and whether the light is steady or flashing, because a flashing warning almost always means act now.

Frequently Asked Questions
Why is the Brake Pad Wear Light on in my Audi A4 Allroad?
