On my '90 Westy, and yours should be similar, the sending unit is
attached to the top of the water tank which you get to by taking off the
metal access plate in the cupboards between the stove and the rear
closet.  Unscrew the top of the water tank and lift it out. The sending
unit is about 16' long with a magnetic float switch that rises and falls
with the water level.  Sounds like yours is stuck.  With the sender out
try moving the float and see if your display panel changes readings.
The VW part # is 255 070 812.  Good Luck.
