Default Problem.. kinda?

Not sure if this is normal or not, since I've never driven another C4 before, but after about 5-10 feet of driving it out of being parked it makes a whurring-hum noise from the back. Like from the rear wheel cavity. Any ideas?

Kinda makes me think of the Vette's super rocket boosters engaging.

Sounds like the ABS check. Normal. Does the ABS light on the dashboard also come on for a second and then go off?

Not that I noticed, but when I drive it again I'll look. Does it every time I drive, so it isn't one of those "random occurance" things.

It happens everytime I put the car into drive after backing out of my garage.

Thanks for asking, I have been wondering about that.

Don't remember the exact wording fromthe FSM, but the ABS unit does a self-test cycle at 5 mph after every restart.
