Hi, I have recently purchased a 2006 BMW X5 fully loaded, its my first 4x4 and absolutely love it! I have noticed that sometimes especially in the mornings that the car does not have much power, almost like the turbo does not work. At first I used to stop on the side and switch engine off and on and got better, but recently does not. I cannot seem to find out whats wrong although once parked in my work car park for 10 hours and when I go home, this is fine, Any ideas?
