Why is my BMW X8 making a strange noise when I turn on the AC?

I recently noticed that whenever I turn on the AC in my BMW X8, there's a strange noise coming from the engine. It sounds like a loud whirring or rattling noise. What could be causing this and how can I fix it?

It's possible that your AC compressor is failing or the bearings are worn out. I would suggest taking your car to a trusted mechanic for further diagnosis and repairs.

There may be debris or dirt stuck in the AC vents, causing the strange noise. Try cleaning them out and see if that helps.
