So I noticed something today that may or may not be cause for alarm. In 3rd or 4th, when giving full throttle at low RPMs, there’s a slight chirp sound. I can only hear it with the windows down and the radio off, but it’s there.
Again, no, this isn’t the BPV venting on a shift or when coming off throttle. It may just be hitting max boost and venting the rest, but the BPV makes more of a “pshhh” sound than this, which is definitely sharper and higher-pitched.
Am I just being paranoid? I’ve had two things go wrong with this car this week, and I’m starting to consider if I might have accidentally parked on an indian burial ground or something.
