Hi All... Long time reader.. First time poster... I have a 2005 X3 3.0 with 70k on it. I've had no real problems so far, but..... I've got a troubling noise with cold starts I'm thinking it's in the transfer case area. I've changed the fluid and that has made it feel a lot smoother I think, but the noise is nasty. Following is a video clip with the sound that I put on youtube. I would greatly appreciate any thoughts... Oh, also, I do not have the triad or any other trouble lights coming on. Could it be the actuator? I have not taken it off to look at the condition yet.....
