I got a 00 323i with just under 220,000 miles on the clock, I've just added a CAI, Conforti Shark Intake and a new SuperSprint and just began having intermitent coolant light issues. I've checked my coolant level and it's not low, I'm not getting any over-heating issues however sometimes going uphill and downhill I get a coolant light on the dash which comes on and goes off intermitently. I'd appreciate any and all possible causes or conclusions. Thanks in advance. Happy Motoring...
