I just had an '84 here that had the blinking coolant light thing.  I found
that the wire to the level sender was broken.  I spliced the wire back
together and it fixed the problem.  So, yes an open should make the system
blink and on these older vans, the temp needle will peg out.

I would agree with you that the Bentley is really sketchy about this sender
system.  Does anyone know where the "Coolant Level Sensor relay" is located
in an '84 Vanagon?  It is not with the rest of the relays, and I couldn't
find it after spending some time searching under the dash.  Just curious.

Thanks,
