AC Compressor? Try turning the AC off and on, see if it stopps\resumes. Mine use to squeel like metal griding... like the bearings were shot or locked. Probably the reason why my AC dosn't work anymore.

this seems to be a common problem for e36's. It's the clattering noise I can't describe. I have that same sound too. Have no idea what it is. My friends bmw does it to. used

[Wurzig-Drei]

I get the same thing in my car after a big rain, or if my AC is on. Did you notice it after it rained?

[bitcore]

It's a terrible noise to have on a such nice car! I don't hear it anymore, thank god, probably because my AC is completely shot.

I get the same noise.

I also get a sharp squeel when the car is in drive or reverse. You can still hear it when you are in park, but it's not nearly as loud. It also goes away when I give the car a bit of gas - but then the squeel is replaced by the occasional churping you described.

I beleive it's the drive pulley, but I'm not positive. All I know is they are both REALLY terrible noises that I can't wait to get rid of.

Sounds like the pulley to me, check the tensioner. You might also need a new belt.

[RIBEMR26]

Mine has the same chirp in idle...and every time I take it back to the dealership because it is under extended warranty they tell me they dont hear it. Makin' me crazy!!!!!!!! ghead

[dutchbmw]

When mine is in idle, I hear a chirp noise too. I'd think it's normal!

[EcianIce]

wow, i have the same problem on my93'. it's most definatly the pulleys for ideling

[camnipotent]

I had the same problem in my old car. It was one of the pulleys just before the alternator. Usually you can just replace the pulley or lube it up and it will go away.
