     THis sensor in the coolant tank controls the dash light!
     The sensor you want in near the thermostat!

   It sounds to me like a wiring problem that I had.
   Trace the wiring from engine to computer. Easy job. Just need the
   book. Pull on wires gently. You will probably find the problem
   in the temp sensor wire where the engine rock! With a meter you
   can test the temp. sensor. No need to replace if tests OK. This
   is a common problem in the Vanagon!
