THE MICRO POWER MODULE IN THE TRUNK WAS BURNT ON MY 2005 530I, NOW MY IDRIVE / AUDIO / NAV AND PDC HAS SHUT DOWN. CAR STARTS AND DRIVES NORMAL, EXCEPT THE PREVIOUSLY MENTIONED ACCESSORIES THAT NO LONGER WORK, WHO KNOW WHAT OTHER DAMAGES (IF ANY) RESULTED FROM A MPM MELTDOWN.

FROM WHAT I COULD VISUALLY ACCESS, ONLY THE MPM UNIT BURNED OUT COMPLETELY AND MELTED. I JUST HOPE THAT I KNOCKED THE MPM OUT BEFORE IT COULD CAUSE ANY MORE DAMAGE TO THE CAR'S OTHER ELECTRONICS. MY CAR IS UNFORTUNATELY NO LONGER UNDER WARRANTY.

MAKES YOU THINK THAT THEY REALIZED THAT THERE WAS A DEFECT WITH THE VEHI
