I am a new owner of a 2004 G 500. When I engage the differential locks by pushing the dash buttons in correct order there is a quiet humming noise that starts after the center button is engaged, continues through the rear and front lock engagement and stops when I disengage all locks. The noise seems to becoming from lower dash, transmission area. All the locks engage and disengage with no problem. Is this normal?
