Buzzing noise in cabin
I need help identifying what this buzzing noise is inside the cabin. I hear it on the Left side of the car. It usually happens a minute after I start the car up after unfolding the mirrors.

Vacuum Pump -- LEFT Front Fender
Quote:
I think that could very well be the vacuum pump as well. It is located in the LEFT front fender area. During your video, I don't imagine you were pressing the brake pedal on and off, right? You could very well have a vacuum leak causing the vacuum pump to cycle constantly. Or it could also be an issue with the vacuum pressure sensor. I'm curious if there is a panel in INPA or ISTA to observe this very thing that could possibly help you diagnose properly...hmm.

Is the sensor itself replaceable? I see it only available as an assembly.

BTW, I tried looking in ISTA and INPA for a panel to run the vacuum pump. I cannot find ANYTHING to try and test the pump.
Whenever I try to do a search, "FUEL" pump comes up...even when I explicitly searched for "vacuum." -_-
