maybe try spraying some wd-40 or something like that on the belt. if it quiets down or stops it, you need a new belt. because, it will soon start doing it again.

oh no! another bimmer. haha. yes, thats it. goes around the pulleys. about an inch wide. i would suggest getting someone to help or just take it to a place and have it done. will not be expensive. the belt cost is around 20 dollars. may take 5-10 minutes to do.

AC clutch bearings could have seized. Turn off the AC/Heat and see if the noise stops.

If you spray WD40 on the belt, you are going to need a new belt period.

Keep your foot off the gas. Problem solved.

I normally think metal on metal when someone says screeching sound, but yes the serpentine belt would also make a screeching noise. A rattling sound usually indicates that something is loose, are you sure you don't have two problems?
