Getting these turbos replaced is like open heart surgery for the car. They have to drop the drive train and tranny and remove the engine.
My current Z4 has, after a few months of ownership, had a slight whine but it hasn't changed at all after 22K miles.

Not sure who replaced your turbos, but it is not necessary to remove the engine to replace the turbos.
