Why is my Audi A5 making a high-pitched whistle noise when I accelerate?

I recently noticed a high-pitched whistle noise coming from my Audi A5 when I step on the gas. It seems to be more noticeable at higher speeds. What could be causing this and how can I fix it?

Your Audi A5 might be making a high-pitched whistle noise due to a faulty turbocharger. Have a mechanic inspect and potentially replace the turbocharger to resolve the issue.

Check for any loose or damaged seals on your air intake system. These can cause whistling noises when air is escaping. Replace any damaged seals to fix the issue.

It could be an issue with your exhaust system. Have a professional inspect and potentially tighten or replace any damaged components in the exhaust to eliminate the whistle noise.
