Hi all.. Need some advice here. I'm looking into updating my current 2008 S550 side mirrors to the newer 2011 facelifted side mirrors. I saw a pair of OEM 2011's on eBay with the exact same plug as my 2008 mirrors. Does anybody here have any experiences in this mirror update? Will I encounter any cel errors or problems? If the plugs for the 2008 and 2011 mirrors are the same, does it mean they're direct swap capable? Am I better off buying aftermarket facelifted mirrors for the 2008 S550? Any inputs or help would be highly appreciated. Thanks.
