Why does my Audi A8 make a strange noise when I turn on the air conditioning?

I recently noticed that when I turn on the air conditioning in my Audi A8, it makes a strange noise. It doesn't affect the performance of the car, but it's quite loud and concerning. Does anyone have any insights on what could be causing this and how I can fix it?

Hi John, this could be due to a faulty air conditioning compressor. I would recommend taking your car to a mechanic to have it checked and replaced if necessary. Hope this helps!
