Electrical question - influence of cold weather on resistance values?

[radek at istar.ca]

I'm trying to diagnose the problem with my EuroVan (has a 5-cyl like the other Audis).  It
started
cutting out at idle.  Looks like an ignition problem, so besides replacing the cap/rotor,
cables and
adjusting timing, I thought it might be a good idea to check the coil.  It looks OK
though, based on
what you guys told me about the meter.
Thanks very much for your help.
Radek.
