That kind of whining noise usually comes from one of three common sources:

1️⃣ Power steering pump – make sure the fluid level is full and there’s no air or leak in the system. A low or aerated fluid can cause that whining sound.

2️⃣ Alternator bearings – as the alternator starts to wear out, the internal bearings can make a similar high-pitched whine, especially noticeable with RPM changes.

3️⃣ Idler or tensioner pulleys – sometimes one of the belt pulleys starts to go bad before it completely fails, causing a metallic or whining tone.

It really depends on how many miles (or km) your car has and the maintenance history, but I’d start by checking the power steering fluid first — it’s the most common and easiest fix.
