How can I fix my Audi A4's faulty brake pedal?

I have noticed that my brake pedal in my Audi A4 has been feeling spongy and unresponsive. What could be causing this issue and how can I fix it?

One possible reason for a spongy brake pedal could be a leak in the brake fluid. It is important to get this checked and fixed by a mechanic as soon as possible, as it could potentially compromise your car's braking system. As a personal tip, always make sure to regularly check your car's brake fluid levels and get them topped up if necessary.
