High pitch whine

Without starting your car, hit the starter button twice to turn on all the electronics. I am hearing a distinct high pitched whine in this mode. I haven't left it

Default High pitch whine

Without starting your car, hit the starter button twice to turn on all the electronics. I am hearing a distinct high pitched whine in this mode. I haven't left it in this position for longer than about 30 seconds to see how long this will last, possibly indefinitely. Has anyone else heard this? I remember reading a while back in the G37 threads that some were experiencing something similar to this, don't know if this is the same thing or not. I have a base w/sport BTW, no Nav.

Yes, I hear the high pitched wine. I thought it was my wife at first , but after concentrating, I was able to block her out and actually hear the wine you're talking about. Sounds electronic and I only hear it at idle speeds with the radio off..after that, the road noise covers it up.

You know, I have been waiting for the girlfriend/wife reference since I posted this

I can't hear it when the engine is running, but it is annoying. My hearing is still good, and high pitched sounds that are continous give me a headache. I wonder what it is?

Well I have really bad ears from working with airplanes for 4 years so I never got to hear it, though my girlfriend complains it about all the time. She said it gives her a headache. :<

Do you all have the same base sport configuration? My touring + nav has a very faint hum, not so much a whine, but I believe I know what kind of sound you are describing. It's similar to the high pitched whine that tube TVs give off, right?

Or the high pitched electrical whine overhead lights, that are on a dimmer, can give when dimmed.

I hear it too. I had been meaning to track it down, but never got around to it. It's coming from either deep in the dash, or in the engine bay. The time I notice it most, is when I shut down the engine, because it lingers for a couple of seconds and the dies off in an ugly-sounding way.

Yep, same here. If you always start your car straight up, and never just turn on the accessories (two clicks of the start button), the engine will tend to drown it out.

I have isolated what I am hearing, it's coming from the engine bay, under the engine cover. I noticed when I rolled the windows up it was less pronounced. Got outside the car and could hear it coming from the engine bay, raised the hood and voila, it's emanating from under the engine cover.

This jives with what I've heard. I notice it parking at home in my garage. I usually have the window rolled down when I pull in, and then when I shut off the engine I can hear it distinctly for a second or two, then it dies (it doesn't just end, it *dies* heh).

Same here. I am not the engine guru you are by any means. What do you think it is, electronic ignition, fuel injection?

Are you guys talking about the whine that comes from the ballasts for the HID bi-xenon headlights? If so, then that's normal. All HID ballasts give off a high pitched whine.

If not, then I don't know. Sorry.
