If you're still under a warranty (original or CPO), definitely take it back to the dealer and have them repair it. This sounds to me a lot like a relatively common problem with the N52 engine and its lifters -- although yours sounds more pronounced than others I've heard.

This problem gets discussed pretty regularly on the E83 X3 sub-forum (the 128i and the E83 X3 share the same N52 engine); in fact, here's a recent thread on the topic. The fourth posting in that thread (by "jdauria") covers the essence of what's going on pretty well, as well as what measures BMW will take to rectify the problem.

Good luck!
