Air Pump! It is located up in the fascia by the left DRL/Turn signal.

Re: whine at startup (prt98)
when you first start your car , active handling is warming up... it takes under a minute then you can here that whine stop... this whine does Not change with engine rpm.
Sometimes if your start your car... especially on a cold day.. and make a hard right or left turn before active handling has warmed up...( usually under a minute ) you will get a DIC message " Active handling warm up"

Sorta sounds like a bedroom issue from the title. :lolg:
Takes a while to warm up and then quiets down.
Seriously, What about the air idle valve on the intake. The air pump sounds like a muffled hair dryer so that is probably not the cause. Put a stethoscope on the noise (screwdirver also works) and isolate where it is coming from.

Every C5 with an AIR valve makes this noise.. And last I checked, every C5 sold in the U.S. has an AIR valve! It's that assembly that attaches to the drivers-side exhaust manifold, the crap that gets in the way when you try to change spark plugs! :smash: :cheers:
