No start 2000 A6 2.7t

[Peter Golledge]

Trust the wisdom of the list, a really dead battery acts like a huge 
resistor straight to ground and prevents sufficient voltage for both the 
ECU to work right and the starter to turn. :-)  If you want to avoid 
spending $$$ to see if it is worth a purchase just grab a sufficiently 
large battery out of another ride and connect it with jumpers in place 
of the dead unit.

My best story of woe was trying to start a Ford diesel at 9000ft after a 
-35F night... engine heater was plugged in all night but unbeknownst to 
us one of two batteries froze.  Even with another running Ford diesel 
(dual alternators and two batteries!) all we succeeded in doing was to 
get some high amp jumper cables to smoke!  Stopped everything and 
disconnect the fozen battery and it started like a charm. ;-)
