What the heck is this sound?!

Does anyone know what this sound is? I've never heard it before, but I heard it tonight after turning my car off. Went for about 30 seconds and then stopped. Before it stopped completely it stopped and started again like twice (in a not very rythmic manner), so the inconsistency of it makes me think it isn't normal. Turning the car on and back off again didn't reproduce the sound (including stepping on the brakes) but driving it around the block DID get it to do it again, which is when I captured the video. Hard to tell where it's coming from, but I *think* it's coming from the ABS module? Would any part of the lights make that noise? The high/low beam shutter was functioning normally. Don't feel any associated vibrations anywhere when I touch various parts of the car, and the sound is hard to pinpoint. No other warning lights, symptoms, odd brake feeling, or anything else...

WTF is that?!?!

Your ignition is still on, though. I hear your TB servo humming after the crazy sound stops.

Hmmm... after listening a few more times, maybe it is the TB.

The hum/buzz you hear is the normal sound made by the HID lights which stay on for a period of time after shutting the car off.

Ignition is fully off. I pressed the Start/Stop button to turn the engine off right before taking this video.

Ok, gotcha. I'm sticking with maybe TB. If you can get it to repeat see if you can feel it there. Whatever it is, once you lay hands on it you'll know it.

Yeah I'll have to mess around with it more. Long day so I'm going to bed now, lol. I'm actually starting to think it might have been the fuel pump, since it's that kind of a sound. Not really an ABS pump kind of sound, lol.
