VIDEO: Possible ABC Pump or other?
Our SL550 is bone stock, been running wonderfully has 47k miles. Suddenly it's started to make that "whirring" sound like the ABC pump...
Anyone know if that's what this sounds like or otherwise?
I took a video of it here:

Take an automotive stethoscope, if you have one ... a 2 ft. length of water hose if you don't ... and trace the source of the sound. I'm guessing ... based on experience with that sound ... that the ABC pulsation dampener has died.

I agree. Mine will make that noise for a few seconds on startup but quickly goes away.
