Help Needed. What is happening?

[Rubba]

Hey Everyone,
The engine is making some weird things like...
- Engine it self making an air flow sound like Turbo out from the exhaust after revving, but the engine is FSI.
Watch this video http://pc.cd/Erp7 listen carefully second 8-10

- Engine seems to be stopping for a Milliseconds
Watch Video http://pc.cd/10X7
When i open the engine i see that is working but stops for Milliseconds and work again.

- Can anyone tell me what this tube does?

It just looks like a 2.8l V6, not an FSI.

The air sound you hear is air getting sucked in past the butterfly valve (throttle body).

The engine "stopping for milliseconds" looks like it's just idling. I don't know if the 2.8's normally idle that low or not.

That "tube" is a bundle of wires.

Do you have a CEL, car running rough, an actual problem with it, or were you just thinking those things were strange?

Yes i was thinking it was strange because i never heard something like that before, but i have a problem with engine stall after Voltage is dropped to 12V.
I have been told it's maybe something related to ecu. Will check about it soon

Alrighty, good luck with it. I don't know too much about the 2.8's otherwise I would offer more help.
