Why does my Audi 80 make a high-pitched whistling noise while accelerating?

I recently noticed that my Audi 80 is making a loud, high-pitched whistling noise when I accelerate. It seems to be coming from the engine area but I can't pinpoint the exact location. What could be causing this and how can I fix it?

It's possible that your Audi 80 has a problem with the turbocharger or a leak in the intercooler piping. It's best to have a mechanic check it out to determine the exact cause.

Have you recently changed your air filter? If it's dirty or clogged, it can cause a whistling noise while accelerating. Try replacing it with a new one to see if it resolves the issue.
