Changing the coolant in a 5k is a pita ..

[George]

Changing the coolant in any Audi is a pain. Why Audi thinks spilling coolant
all over the bell housing from the heater valve is a drainage method that
allows you to recover coolant defies reason. 

I have driven a '91 20V since new and when putting in the second radiator I
tapped an outlet into the bottom tank and led a hose and valve to below the
bumper. End of problem.......

LOL! Hardly, it sometimes just takes looking at it from a different  
angle ;-). We also don't know that the coolant flow from te after run  
pump would be enough to change the whole system. Does the flow path  
include the heater if you open the heater valve?

http://www.sjmautotechnik.com/trouble_shooting/cooling.html - The  
image towards the top of the page suggests to me that it would do the  
whole system, but then I remembered the t-stat. Even if you start with  
a piping hot engine the cooler stuff you pump in would shut the stat  
right quick :-/. I guess the flow through the head and turbo would  
by-pass the stat though.
