Ed, I have not resolved this problem and you may have the answer.  I have a newly installed 2l in-line 4 VW engine and using a coolant tank from a Eurovan which has the level sensor incorporated in the tank.  For the first few hundred miles there was no problem then all of a sudden this coolant light problem came up.  I will order in a new tank and try that to resolve this problem.
