Why do I hear a strange noise from my Audi A2's engine when I accelerate?

I recently noticed a strange noise coming from my Audi A2's engine when I accelerate. It's a loud humming sound that only happens when I press down on the gas pedal. What could be causing this and how can I fix it?

Emma, it sounds like your Audi A2's air intake may be clogged. This can cause a buildup of debris and can lead to a humming noise when accelerating. I would recommend taking your car to a mechanic to have the air intake cleaned or replaced if necessary.
