[Vwdiesel] tdi heat

[Chris Geiser]

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!!
