Engine Vibration

Engine Vibration
I have a 09 g37 sedan and i use redline oil only, yet i still have the weird VVEL noise. I have had the TSB done twice, so whatever was done does not seem to work longterm. So instead of going to the dealer am I able to have a tune done to the car that will eliminate it? Or am i stuck with the dealer
every so often? Is it possible that the cam sensors are going and causing this? I have no CELs...
Also, here is a description of the noise: at idle i can hear it, but when VVEL kicks in it is a loud vibration that goes in a nice wave pattern. Is it the VVEL or something else?

i hear it most when i am cruising at about 75 mph and rpms are about 2700-3000. I'll double check this morning. It is coming from up front. Checked motor mounts, trans mount and driveshaft for anything suspicious, nothing.

Okay, I have tried to get a good recording of it, but every attempt didn't have anything noticible.
So, I have noticed something weird:
In the morning on a cold start it makes this noise. Once it is warmed up it still makes the noise. If I come to a complete stop and shut it off and start it up again the noise and issues I hear go away. Also, since the mornings have been in the 60's+ it doesn't happen at all... So it appears to be related to cold weather. Any ideas?

when was the last oil change and how is your oil level? perhaps you may want to switch to another full synthetic motor oil and see if the noise goes away.
