Oversensitive ESP?

[anzer]

Update - I've found if I ease off the brakes completely before hitting the speed bump and "free ride" over it (i.e.no brakes usage) the problem goes away .... she's a sensitive old girl this X5 - I've also noticed that sometimes when I gun it away from lights and there's a few potholes the ESP picks them up and lights up the ESP accordingly - this means a slight millisecond power cut - suppose its all just doing its job ..
