Anyone had any experience with this annunicator what the cost was to have it resolved. Had a 1998 528i where I struggled with a 'check engine light' for 5 years before I finally got it fixed. Hope the 'fixes' are similar. Any help/input would be appreciated.
Just on a lark...have you checked the health of X's battery? I ask because it is approx 7 years old (normal life cycle of the original battery)...and that warning is notorious for showing up when battery voltage drops below 11.89 volts (and battery is on it's last leg).

Just a thought...especially if there doesn't appear to be any other issues or symptoms of engine failure. Are you having an other odd electrical glitches that may be indicating the battery as a possible culprit? Do OBC TEST 9 with the ignition in position 1 to see what the battery's voltage is...or if you have a multi-meter...you can use that.
