Just came back from the dealer. The shop foreman drove it and determined that he's going to order the belt tensioner and belts as mentioned in a previous post.

He commented that it was the same sound that was coming from an X6 50i. They replaced these parts and the problem went away. Part should be in next week. We shall see..
