Are you talking about the high pitched whine? I have that too. It is really clear if you just hit the start button twice and put the car into acc mode. A few other members have reported it too but no one has had any issue with the car with this noise present from what I can tell. I believe the noise comes from the alternator. Atleast that is where it sounds like it is coming from.
If you have access to a stethoscope remove the end to where its just the open hose and you can use that to pinpoint noises.
