I have a 1999 S80 T6 w 150K miles. Over the past few days part of the LED\ndisplay started disappearing:\n\nFirst the F (in degree units) went to a stick (like I), then within a day\nor so the second digit went on the actual degree measurement so 70 F now\nlooks like 7 I. Now another day or two later the D for "Drive" lost its\nbottom line. All of these are wihin a short distance of each other - the\nrest of the display is fine. Another strange thing is that at night when the\nlights on the dash dim, everything works perfectly!\n\n\nAny ideas on what this could be? Also, I am not about to mess with removing\nthe dash, etc, so any idea how much something like this might cost at the\ndealer? Finally, the bulb behind the temperature setting knob went a couple\nof months ago - should it be any more "labor" to get to that if one already\nhas the thing open to repair the above? (I can definitely live without the\nknob light.) Thanks.
