Greetings all, I have a 2004 2.5T and just recently noticed a sort of whining or whizzing noise coming from the front drivers side of the car. I know it's something electrical as the noise is present whether the engine is on or off, but only as long as at least the ignition is on. It's not one of the many cooling fans of the car (cooling, A/C or ECM/TCM). It actually sounds similar (though louder) than a fuel pump sound. An '01 S40 I used to have had a noisy fuel component by the tank, and it's comparable to that. With the hood open, the sound appears to be coming from the intake airbox area. I'm not overly concerned, just curious what that is or might be. No CEL, red/orange triangle or any codes being given off, no reduced power either. Just a whining sound that's sometimes annoying.
