2013 28i xDrive MSport with lighting package here.
Have puddle lights on doors, lighted vanity mirrors and led ambient lights in overhead console, center stack cubby and all 4 door pockets.
Last item on page 82 of manual refers to Ambient Lighting.
"Depending on equipment the lighting can be set individually for some lamps" with iDrive menu directions for selecting the desired color scheme. Ours does not have this particular menu option! Dealer unable to say if ours (or MSport's) should have this feature, or if it is limited to specific trim lines, but is checking for me. Suspects this feature is available only on X and Sport trim lines.
Will post the outcome of the investigation!!!
