Why is my Audi A4 making a strange sound?

Recently, I've noticed that my Audi A4 is making a strange sound when I accelerate. It almost sounds like a high-pitched whine. What could be causing this and how can I fix it?

Hi Max, thanks for reaching out. The strange sound you are experiencing is most likely a result of a damaged or worn-out fan belt. This can happen as a result of normal wear and tear on the vehicle. I suggest taking your car to a mechanic to have the fan belt replaced.

Hey Max, another possibility for the strange sound could be a loose exhaust pipe. Over time, the exhaust pipe can become loose and cause a rattling noise when driving. I recommend having a mechanic check the exhaust system and tighten any loose connections.

Hi Max, it could also be an issue with the engine. If you notice the sound is coming from underneath the hood, it's best to have a mechanic inspect the engine for any potential problems. Don't wait too long to get it checked out, as it could lead to more serious issues.
