Like I said, just a wild a$$ guess.
I was going to suggest and say the same as what ala_xfire said! In my experience it will be the wheel speed sensors that are causing this, they can be pretty sensitive! When the BAS/ESP light comes on there is a "trick sequence" involving turning the steering wheel to get the light to reset and turn off. I have done this previously when I triggered the wheel speed sensors when I was doing some work on the car, did that sequence and light hasn't been on since!
