Why is my BMW 2 Series engine making strange noises?

I recently noticed that my BMW 2 Series engine is making unusual noises, especially when accelerating. What could be causing this and how can I fix it?

It's possible that your engine is low on oil, causing it to make strange noises. Check your oil level and top it off if necessary.

Another possible cause could be a loose or worn-out belt in your engine. Have a mechanic check and tighten or replace any worn belts.

If your car is old or has high mileage, it's possible that your engine is just naturally getting louder. As long as performance isn't affected, this may not be something to worry about.
