I still have full power, though...and the sound is new, but very faint.

I have a 12/00 build, and was wondering if this sound is inherent with turbo failure, or is it just the sound of my turbos working a bit harder (if you know what I mean)..

TIA

I doubt the siren noise, is an accurate predictor

of turbo failure

to figure out if it's the left or right turbo or both. My car runs great.

Yeah. Loud and lots of smoke coming out the exhaust are subtle clues

Well, if it's a faint sound like you said. My understanding is that a blown turbo is loud. I noticed the sound the first day I drove with the windows down around town.

high pitched whine that all S4 turbos make. This is a new sound that just started a few days ago.

It is actually easier to hear with the windows up. It is not the initial high pitched whine, but rather a tea kettle, siren type noise.

Sounds like it is not a big deal, though. My car still runs perfect, and is making full boost.....I was just a bit concerned since I had never had that sound before.
