Got into my car this morning and had a very high pitched whine after I started moving. Pulled back into the driveway and it continued, even when idle. Stopped by the time I got into work, guessing because the car warmed up.
Thinking it is a pulley that is about to go, but was wondering if anyone has had a similar experience. It's almost like the turbo spooling up really high, but it happens when idle so it shouldn't be exhaust/turbo. It's almost a more noticeable, higher-pitched sound than the turbo. Considering it stopped by the time I got into work I'd blame it on the engine being cold, but it was 47 or so this morning which is not cold enough for this shit to start happening. What's going to happen when it's actually fucking cold?
It was coming from the engine compartment, when I popped the hood I was drawn towards the alternator area.
