Mysterious noise
Hello y’all
2009 c300 with 80k, only while driving sound coming from front end. Very low whirring that gets higher in frequency when accelerating then loosens and drops as vehicle slows. Quiet under approx 15mph. Sound is not loud can’t be heard with window down or stereo/ac. Any help with diagnosis would be much appreciated.
