Why does my BMW M1 make a loud screeching noise when I turn on the A/C?

I recently purchased a BMW M1 and have noticed that whenever I turn on the air conditioning, there is a loud screeching noise coming from the engine. Is this normal or should I be concerned?

It is not normal for your BMW M1 to make a loud screeching noise when you turn on the A/C. This could be a sign of a failing A/C compressor or belt. I would recommend getting it checked out by a certified mechanic as soon as possible to prevent any further damage to your vehicle.
