I've read that it's a sign of imminent turbo failure. I hear a faint dentist drill sound as soon as I get off the gas, and it sounds electronic, not mechanical. It stops after a few seconds and is the same pitch and volume throughout. I'm hoping this is just some weird sound that comes with turbo engines. I have a rev D diverter valve that I'll be throwing on (I'm pretty sure I"m on the older one) this month.
