Why is my Audi 80 making a whirring noise during acceleration?

My Audi 80 has recently started making a whirring noise when I accelerate. It seems to be coming from the engine area. What could be causing this and how can I fix it?

The most common reason for a whirring noise during acceleration is a worn out serpentine belt. Check the belt for any signs of wear and tear and replace it if necessary.

Another possible cause could be a faulty alternator. If the whirring noise is accompanied by dimming lights, it's a good indication that the alternator needs to be replaced. Have it checked by a mechanic.

A damaged or clogged air filter can also create a whirring noise during acceleration. Check the air filter and replace it if it's dirty or damaged.
