No error codes.
Basically every time I accelerated, I could hear a slightly high pitched whining noise in the background from 2500RPM and above. It kinda sounded like the turbo spooling, but a bit different sound. Sorta like in older cars when there is interference with the speakers when accelerating. Hard to describe.
It was really noticeably with windows up and radio off, and especially in 1st and 2nd gear, but hard to tell where it's coming from.
SA compared with a similar vehicle to make sure the sound wasn't normal. He initially thought it might be from the audio system, but turned out to be the tranny.
If your hearing a noise and your sure it isn't the turbo, would recommend taking it in to get it looked at.
