Nothing really to add here, but I just programmed a double and a single garage door without a problem. I have liftmaster too but not sure which model. Also, my manual says press the homelink key 3 times after you hit the program button on the garage motor. You may want to move your car around? When I program mine the car is inside the garage in the center slot, so the double garage motor is directly above the right edge of the car, whereas the single garage is further away (half a car's width to the left and above). Since your sequoia works, I really think the bimmer should work... good luck!
