Hellow clubwrx. I really wanted my first post to be in the new member's hangout. I have read and read on the forums and appreciate the information from everyone!
I bought a 2012 WRX, about 3 weeks ago with just under 20k on it. My first turbo and my first AWD. I've had tons of questions answered on here, through tons of reading.
Today I noticed my turbo was not spooling. I rarely have situations where I get it over 3k, so I have no idea how long the spool has been gone. After dinner I jumped on the interstate so I could get the revs up and verify it was really gone. It has been hot and humid and I thought maybe that was just affecting the sound. No spool sound at all, all the way up to 5k.
As I got off the interstate I ran it back up, in second gear and just before the red light I could hear a very loud high pitched sound. Maybe like bearings, instead of spool. There was no grinding noise, just a very short loud whistle/whine. I took off from the red light and between 4-5 k, it made that sound through all 3 gears.
Bummer. New car.
Any thoughts? TIA.
