I have a 04 BMW Z4, and noticed a squealing noise when I accelerate slowly. Has any one had this issue, and if so how was it fixed?

I don’t own a Z4, but I’ve had squealing noises before and it is usually a belt.

Yup!  
If your drive belt(s) is/are the original ones, then it is time for replacement.  
If the drive belt(s) is/are fairly new, then you should have your mechanic check the belt tensioner(s).
