I'm gonna try listening to the turbo with a heater hose later today. I'll post back as to whether or not it was coming from the turbo housing. As of now its more prominent on the passenger side and almost sounds like the belts/pulleys and usually occurs on a hot day after a bit of driving.

Wasn't able to hear anything when I listened to various points on the turbo and around it. I'm replacing my EGR valve tomorrow and I plan on doing a boost leak test afterwards... might be a leak somewhere (atleast that's what i'd rather it be).

OR you could just take the compressor inlet hose off and have a look see. Takes 10 minutes tops.
