Alright, I will first explain the noise I hear (again).
It's a high pitched squeeling noise that gets much louder once the shifter is in drive. It also gets louder once the AC is turned on.
You might say it could be the belts? Well, been there! Changed them all! Yet, the noise remains!
I then discover I have a leak in my radiator so I think maybe this could also be the cause of the noise. Possibly the steam coming from the leak? Nope! New radiator and the noise persists! I also change the air filter (which wouldnt be directly the cause but thought maybe it was air squeezing through a dirty or leaky filter, but nope! Still there!
Could a water pump make this noise? I have yet to replace that. That is the only thing I can think of!
If that is the case I probably will have to remove the radiator I just installed! Ugh!
Please give me your feedback guys! I'm very curious to see if you have similar issues or know what the problem may be!

Sounds like typical belt squeal which gets louder when more load is placed on the belts. If the belts are new then it probably is that they aren't tensioned properly or something is wrong with one or more of the pulleys.
One of the pulleys is attached to something that looks like a shock absorber which automatically puts the correct pressure on the belt. If it's not working properly your belt will be loose. This is not something that a mechanic would routinely check. Also, one of the pulleys could be misaligned, loose or worn, and this is also something that wouldn't normally be checked.
Hopefully this problem was solved. I have a similar but different problem on my '96 328ic (160k miles). My whining noise seems to be coming from the general area of the pulleys and belts but only happens after I stop fast at a light. The car runs fine, standard engine noise, if I brake soft and roll up to a stop sign or traffic light all is well. The moment I jump on the brakes for whatever reason I immediately get a whining noise that is lower in pitch in idle and goes higher in pitch as I accellerate. It doesn't usually go away until after I stop at my destination park for a time, come back and start the engine and drive off. Then it's back to fine until the next quick stop. Brother said low oil, nope, topped it up. Bearings? Why doesn't it happen all the time?
I did have the alternator replaced 4 months ago, had a little whine every once in a while but went away in 5 minutes and didn't return for 2 weeks or so each time. Now every time I stop short the whining begins. I am almost sure it's not coming from the alternator as I have heard that the Bosch brands can whine a little from brushes? I have put my ear right next to the alternator and no whine. Seems to be coming somewhere else.
waterpump? maybe the extra force on it jogs it and the bearing squeaks.... when was it last changed?

Also, if the water pump had problems would the car run hot or over-heat. It stays at normal temperature at start or after driving a lot. What about power steering pump. When it's cold in the morning my first left or right turn causes a whine that only happend once or twice and then is fine through the day. The whine is very similar to the other whine but when it happens it doesn't continue. No whine until I hit the brakes hard. Frustrating...
