Why is my Audi A3 making a loud noise when I turn on the AC?

I recently noticed that when I turn on my AC in my Audi A3, there is a loud noise coming from the engine. It sounds like a grinding noise and I'm not sure what could be causing it. Any ideas?

Hi Samantha, it sounds like you may have a problem with your AC compressor. I suggest taking your car to a trusted mechanic to have it checked out.

Samantha, it could also be an issue with your serpentine belt. If it is worn or loose, it can cause strange noises when your AC is on. I recommend having a mechanic inspect it for any damage.

I had a similar problem with my Audi A3 and it turned out to be a faulty AC fan. It was an easy and relatively inexpensive fix. I suggest having a mechanic check your fan for any issues.
