Why is my Audi A1 making a strange noise when driving?

I recently purchased a used Audi A1 and I've noticed that it makes a strange noise when I'm driving at higher speeds. It almost sounds like a grinding or clicking noise. What could be causing this and should I be concerned?

It's always best to get strange noises checked out by a mechanic, especially if the car is new to you. It could be something as simple as a loose exhaust pipe or something more serious. I'd recommend taking it to a trusted mechanic for a diagnosis.
