i have the same high pitched noise coming from my car
it comes around from the turbo area side but im not sure when u listen close up it sounds like the other side
couple of people told me its normal and its possibly the powersteering pump
i just checked the 4 bolts and locktabs on the turbo and they are very tight.. im guessing its powersteering pump that needs replacing or its just normal and im getting paranoid
my noise happens when the car is warm, after a decent boost, then at idle you hear it whining and when you rev to 1500-2000rpm the whinding goes louder, but then u take it for a drive again and it disappears, then comes back and then disappears.. not to sure what to expect
anyone else had this and replaced powersteering pump?
