Coolant level alarm

[provo]

My E34 M60 530iA gives a coolant level alarm when I start the car. After driving off, it disappears.
I have replaced the level switch, but the problem persists. :(
Does anyone have any info for me on this problem? Puleeeeez! :)

I also replaced level sensor with new radiator. I think is the connector to the sensor - maybe wires or connector itself. Have not tried to mess with it because I finally fixed (last week end) an overheating issue that plagued me for months. Hope this helps...
