Why is my Audi A2's transmission making a strange noise?

I recently noticed a strange noise coming from my Audi A2's transmission when shifting gears. It sounds like a grinding or whirring noise. What could be causing this and how can I fix it?

It's possible that your transmission fluid needs to be changed or topped off. This can cause strange noises when the fluid is low or old. We recommend checking the fluid levels and changing it if necessary.

Another possible cause could be a worn out clutch. If your clutch is worn out, it can make grinding or whirring noises when shifting gears. It's important to get this checked and replaced if necessary to avoid further damage to your transmission.
