Is it normal for my Audi A3 to make a squeaking noise when applying the brakes?

I've noticed when I press the brake pedal, my Audi A3 makes a high-pitched squeaking noise. It's not very loud, but it's noticeable. Is this a common issue or should I be concerned?

This could be a sign of worn brake pads. It's normal for them to squeak when they start to wear down. It's best to get them checked and replaced if necessary.

I've had the same issue with my Audi A3. It turns out it was just dirt and debris on the brake pads causing the noise. A good cleaning should solve the problem.
