Has anyone measured (or would anyone be willing to) the resistance at the
two terminals of their "vent line heating element"?
This is a pipe type valve in the 1" return air line from the crankcase
(large cylinder w/ hose at the back) to the main intake air boot, at least
on my Digifant 87 2.1.  This device has a small electrical connector at the
top which powers a heating element inside the vent, to "prevent icing during
cold engine operation" according to the VW Digifant Pro Training Manual,
p.11.

It is supposed to measure 4 to 17 ohms across the terminals of the element
at 77 F, and mine reads 70 ohms (sounds like a problem to me!).  But before
I spend $90 on a new one from VW I'd like to get a confirming resistance
read from someone else's device that is working.  If you have this device,
it is very easy to get to, and the wiring connector just pulls off.

BTW, if you haven't yet seen it, Darrell Boehler's website (Midwesty) has
some very helpful Pro Training Manuals, downloadable, at  www.loam.org/vw.
Thanks, Darrell!

Thanks,
