W211 facelift License Plate Bulb Error




My 2007 E350 has the intelligent light system package and for the past few weeks the licence plate bulb error both left and right has been going on but the bulbs are fine but the error doesn't go on all the time
Then the other time the front left low beam message popped up and went away, what could this be? All the bulbs are fine, but the error pops up ?
I live in Canada, could the road salt and debris could have caused this?
Thanks in advance.
