No smoke. If I pull the vacuum lines off the boost solenoids, no whine. No codes or limp mode. It's hard to tell exactly where the sound is coming from but it seems like it's coming from the rear drivers side of the engine. The whine doesnt sound like its coming from around the intercooler and I feel no leaks around the charge pipe.

Do you guys have any suggestions or ideas of what to check? I'm actually on vacation in OCMD so I'm in a bad spot.
That’s definitely a blown turbo or turbos. Upgrade time
