E90 binding brakes

I am having a problem with binding brakes on my 2008 E90 pre lci 330d auto . In the mornings when i drive the car out of the garage (i park the car with the back end first) that the brakes bind for about 100 metres or so before i can hear and feel the car moving freely. Have any one had a similar experience and what was the solution/cause? Car has 91k on the clock and is still under MP. I want to resolve the problem before it goes out of MP in July.Thanks!
