Mine is a 2010 135i and no squeaks till now (800 miles); my armrest only squeaks when I put my elbow on it. The sound is very much like plastic on plastic and not particularly loud. The earlier miles however this BWM was tight as a drum (as the saying goes), but now I'm hearing the old squeak and unidentifiable sound that may or may not be a rattle (or something loose) in the dash. Since I've added nothing to the glove box, I don't know what it would be. LOL, hun.
