Hey everybody! Great site. I'm new here and a new first time BMW owner. I just purchased a 2004 Jet Black 745Li. One problem that i've noticed initially is a slight hesitation upon accelerating from a stop. Other than that the car seems to run very strong. Additionally, if i was last listening to a CD in the changer when i last drove the car, sometimes when i start the car it goes to the radio and i can hear it cycling through the CD's in the changer as if i just put the CD cartridge in. Any thoughts?
