Engine races about one mile after starting

My daughter's 04 325i Steptronic (116K miles) is exhibiting the following symptoms:

After starting it up, she drives it about one mile till she comes to the stoplight leading out of our neighborhood. As she pulls away from the light, the engine races up to a high rpm (5-6K, indicated on the tach), but the car doesn't accelerate commensurate with the engine speed. If other words, if it were a manual transmission car, it's as if she pressed in the clutch, and floored the accelerator.

It does this for about as long as it takes he to complete the turn, and then everything returns to normal. It doesn't do it again on the rest of the drive. I've tried to duplicate the symptoms, but so far, it hasn't done it for me. She says this has been happening for about two weeks. I'll have the codes read asap. Any ideas? I did a search under "engine racing", but nothing turned up. Thanks.
