Why does my Audi A5 make a whistling noise while driving at high speeds?

I've noticed a faint whistling noise coming from my Audi A5 when I drive at speeds above 80 mph. It seems to be coming from the front of the car. Is this something I should be concerned about?

It is likely that the whistling noise is coming from the air passing through a small opening or gap in your car's aerodynamics. This is not uncommon for sports cars like the Audi A5 and should not be a cause for concern. However, if the noise becomes significantly louder or more frequent, it is always best to have it checked out by a certified mechanic.

From personal experience, I have found that adding a roof rack or wind deflector can sometimes cause this type of whistling noise. Try removing any additional equipment from your car and see if the noise persists.
