Why is the BMW X1 making a strange noise when I turn on the air conditioning?

I've noticed that whenever I turn on the air conditioning in my BMW X1, there's a strange noise coming from the engine. It sounds like a high-pitched whine and it's concerning me. Is this something I should be worried about?

Hi John, thanks for reaching out. The noise you're hearing is most likely due to a loose or worn belt in your X1's air conditioning system. It's important to address this issue as soon as possible as a faulty belt can lead to further damage and costly repairs.
