[Vwdiesel] tdi heat

[James Hansen]

TDI heat.
lol, good one.

Seriously, to check plugs, use a small old school battery charger with an
analog gauge on the front.  Disconnect the plug, and run current through the
plug.  The meter on front will tell you what's up for current, and compare
with the others to find dead ones.   Failing that, use your digital current
meter, and put a small plug in the wall power supply in series with it.  Run
this through the plug, read current, and compare.  I have found an ohmmeter
to be mostly useless to check glow plugs.

You need heat...
cardboard the rad over until the electric fan runs continuously, then take a
bit off, like a strip at the top an inch at a time.  Only way man.  They
just don't make any heat.
at -40, the rad can be closed off, and the temp gauge drops when you hit the
city and stop at a light just from the heater core. Gotta pay attention with
this setup, but it does work.
Trick is you're keeping the cold rush of air off the motor, which vacuums
most of the heat away when it's cold.  Can try a storm front like a big
truck would use, BTDT, works okay, and less risky than covering the rad
core.  You can cover at least half the rad core with no worries at all
unless you pull some big mountain pass every day.

So after the responses here, I've been reading more about the coolant glow
plugs - sounds like they may not be working (04 Jetta BEW - manual
tranny).  The next time it gets cold, I'll check if there's current to the
plugs - from what I read, coolant glow plug system only comes on when below
14 F (and we're in a heat wave now with +40 predicted for tomorrow).

Also - If I put an Ohmmeter on the positive post and on the block, what
should the resistance be if plugs are good / bad?  Seems to me I remember
that being a legitimate way to check them if not powered by a common bar,
or if I disconnect the bar?

TIA again!!
