Hey and thanks for the add. Have had my m35x for several years now and no issues. Today I was driving down the highway and heard a whining noise in the center console. The noise went down as I slowed a little. After a minute of the noise I heard a small thump and then the AWD light on the dash went solid

. I ran a meter to see if there we're any codes and nothing. The car still drives as normal if that helps.
Any ideas on what the issue is?
