How to troubleshoot low brake fluid in an Audi A1?

I noticed that my Audi A1's brake fluid is low. What steps can I take to troubleshoot and fix this issue?

Firstly, check the brake fluid reservoir to ensure it is not empty or under the minimum mark. If it is, top it up with the appropriate DOT brake fluid. Consider checking for leaks or faulty brake components that may be causing the fluid to lower. Also, make sure to bleed the brakes to remove any air bubbles. As a precaution, get the brake system inspected by a certified mechanic.

Low brake fluid can indicate a worn brake pad or leaking brake lines. Visually inspect the brake system for any signs such as brake dust on the wheels or fluid drops under the car. Also, check the brake pads for thickness and replace if necessary. Don't forget to bleed the brakes afterwards to ensure optimal performance.
