I'm no electrical whiz, but 1 ohm of resistance sounds way too low for a
glow plug.  Try applying power to them while the engine is cold.  If you
cycle them 2-3 times the plug should be noticeably hot to the touch.  I have
had horrendous meltdowns in the plastic socket that holds the control
module.  The meltdowns caused malfunctions in the rest of the system. The
easiest (maybe only) way to remove the glow plugs is to remove the fuel
injector pipes.  Check that braided return hose while you're at it.  The
dash lamp is controlled by the glow plug control module.  I can't remember
which wire it is off the top of my head (Bentley is in the van, of course).
In one of my vans, the PO had installed "fast" plugs and kept the correct
"slow" control module.  The plugs were fried....  I buy mine at a FLAPS
(AutoZone) for $10.95.  Only buy Bosch!
