I had the same problem when I replaced the coolant level sensor on my
85 Vanagon.  The light started flashing again a few months after
replacement.  I finally fixed it for good by giving the contacts in
the connectors a good cleaning, then coating the plug (but not the
contacts!) with dielectric grease before plugging it back together.
This has solved the problem by sealing the contacts away from the
elements.  Seems that just a slight bit of oxidation on these plug
contacts cause the light to flash. (Likewise for the FI temp sensor as
well - cleaning and using dielectric grease has also solved mysterious
FI problems for me  as well).
