Ok so I just got my first m5(2002) not to long ago. Previous owner had put different headlights in it my guess ebay. And also ddm hids. Well the hids were blown when I got the car. Then I noticed that the lights would flicker when cold, and then one day when my wife was driving it the locks/center interior lights quit working. So I just got a used gm3 module and it has fixed those issues but now the lights flicker all the time. The angel eyes, High beams, and interior dash lights that come on when lights are on all flicker. Also the radio will cut out when they flicker. So is my lcm bad... I had the battery tested not to long ago and it tested fine. I have searched forums but wanted everyone's opinion.
