Does anybody know what can cause this. Most times my car starts off with the warning that my driver side brake light is malfunctioning. And when the light is on, the brake light indeed does not work. But after diving for a while, the light goes off and everything works fine. Theni t may come back on gain. Any ideas whats causign this, btw i have retrofit xenons but have not gotten my ecu flased. could this be the cause???
