Why is my Audi 80 making a screeching noise when I accelerate?

Recently, whenever I accelerate in my Audi 80, there is this loud screeching noise that comes from the engine. It stops once I reach a certain speed but starts again if I decelerate and accelerate again. Any ideas what could be causing this?

It is possible that your drive belt is worn or loose. This can cause the screeching noise when you accelerate. Have a mechanic check and replace the drive belt if necessary.

Check your vehicle's water pump. If it is failing or has a loose belt, it can also cause a screeching noise when you accelerate. Have a mechanic inspect and replace the water pump if needed.

Another possible culprit could be a malfunctioning pulley. When the pulley is faulty, it can make a loud screeching noise as well. Have a mechanic check and replace the pulley if needed.
