Why is my Audi A3's steering wheel vibrating while braking?

I've noticed that whenever I apply the brakes in my Audi A3, the steering wheel starts to vibrate. It's not a major issue, but it's definitely noticeable and slightly concerning. Is there a specific reason for this and is there anything I should be doing to address it?

This can happen due to a number of reasons, the most common being worn brake pads or warped brake rotors. It's always a good idea to get your brakes checked by a mechanic to determine the exact cause of the vibration.
