Why does my Audi A1 make a strange whistling noise when accelerating?

I have noticed that when I am accelerating in my Audi A1, there is a high-pitched whistling noise coming from the engine. It only happens when I am pressing lightly on the gas pedal. Any idea what could be causing this?

It is likely that the source of the whistling noise is a damaged air intake or a worn-out turbocharger. I recommend getting your car checked by a professional mechanic to accurately diagnose and fix the issue.

I've experienced a similar issue with my Audi A1 before, and it turned out to be a loose hose connection. It's an easy fix, so make sure to check all the connections in the engine compartment.

Try checking your air filter and replacing it if it is dirty or clogged. A dirty air filter can cause whistling noises when air is forced through it.
