The light still comes on when I unplug the boost sensor. Maybe its just a coincidence but its sure funny. I drove it pretty hard the last time I Had it out, then I screwed with FCD then I started it. The overflow was low but the at the rad cap was full. I topped up the overflow but the light still came on. Hmmm.
