Why is the BMW X1 engine making a high-pitched noise?

I recently noticed that my BMW X1 engine is making a high-pitched noise when I start it up. It seems to go away after a few minutes, but I'm worried that it could be a sign of a larger problem. What could be causing this and should I take it in to get checked?

It is possible that there is an issue with your serpentine belt or a related component such as the belt tensioner or pulley. It's always a good idea to have a professional mechanic take a look at any unusual noises.

Make sure to also check your oil levels and quality. Low or dirty oil can sometimes cause faint noises from the engine. If it's been a while since your last oil change, it might be a good idea to get one soon.

Another possibility could be a problem with the exhaust system. A loose or damaged muffler or exhaust pipe can cause high-pitched noises. Have your mechanic inspect these components as well.
