Why is the Audi A1 making a strange noise while accelerating?

I recently noticed that my Audi A1 is making a strange noise whenever I accelerate. It almost sounds like a whistling or humming noise. What could be causing this issue and how can I fix it?

There are a few potential reasons for this noise, Hannah. One possibility is that there is an issue with your exhaust system, such as a loose part or a hole. Another potential cause could be a problem with the air intake or air filter. It's also possible that the noise is coming from the engine itself, indicating a more serious issue. I recommend taking your Audi A1 to a certified mechanic for a diagnostic test to determine the exact cause of the noise and find a solution.
