I just got back from the dealer, they said mine was related to the injectors and was normal, they're just noisy apparently. I took some video with my phone where you can hear it, will post it up in a little while once I remember my photobucket acct.
Here's a video of mine, it sounds way worse in the vid since I took it with my cell phone, crappy quality but it's all I have for now.

Strokt350d - maybe you can post up a video of the noises yours is experiencing?
