Humming noise from engine compartment around 1800-2100 RPM under throttle - Bluetec
I noticed this morning while driving to work. Under light throttle, I have an audible humming noise (that doesn't seem to fit in with the engine noise) from the engine compartment area. I think it's on the drivers side, but my hearing may deceive me. Tires are in good shape and balanced, no other obvious flaws that I can tell.
Additionally, I also have some differential noise at certain speeds. I'd like to think I wouldn't even notice this if my engine were louder at highway cruising speeds, so I'm not sure if it's a legit worry. My warranty is up in January, so I'm trying to notice anything and everything that could be wrong...
Thanks!
