RE: Audis vs Batteries
The newer turbo-motors do run the radiator fan for an extended period
after turning off the car. This seems to be pretty much independent of
the temperature on my '88 5000CSQ. The cooling fan is run at low speed
and the auxiliary water pump is run simultaneously. All this is done
to ensure that the temperature of the turbo bearings does not get too
high. So far I haven't noticed any problems with the cranking rate even
with the long battery cable. My '83 ur-Q actually seems to have more of
a problem in that department. On the '83 the only fan that can run when
everything is shut down is the blower that cools the injectors.
