Ive been a long time member now, upgrading threw the years from a 2005 4.4i to 2008 4.8i and now the proud owner of a 2012 X5M. She is amazing.... Alpine white, black perf leather with active seats, leather dash...and every option minus rear entertainment. Had 8k miles on the clock.

Now, I have one question.... I am now hearing a whistling droning noise at low speeds. I know it's the turbos, but is it normal to heard them??? I drove several X5M's in my search over the last 6months and never did notice this sound. Could it be the bearings that are bad or is this just normal???

Thanx
