Why does my Audi A2's engine make a whining noise at high speeds?

I recently noticed that my Audi A2's engine makes a high-pitched whining noise when I drive at high speeds on the highway. It seems to go away when I slow down, but it's quite loud and concerning. Can anyone offer any insight into this issue? Thank you!

It's possible that the whining noise is caused by a loose drive belt. It's important to get this checked out by a mechanic as a loose drive belt can cause damage to other engine components. In the meantime, avoid driving at high speeds to minimize strain on the belt. Best of luck!

I had a similar issue with my Audi A2 and it turned out to be a faulty alternator pulley. It's a relatively easy and inexpensive fix, so don't panic yet. Take your car to a trusted mechanic for an accurate diagnosis. Hope this helps!

The whining noise could also be due to a low level of power steering fluid. Check your fluid levels and top up if necessary. If this doesn't solve the problem, it's best to have a professional take a look. All the best!
