Thanks for the reply! You ROCK!

The mixture is of MB origin and sounds as if i will need to replace the tank.

I'll re-check the electrical connections and give it another week to see if there is any fluid loss. If all appears stable, i'll order a new tank and that will hopefully put this gnat of a probelm behind me.
