The new radiator may have additional coolant capacity; but it won't have additional air flow capactity.  The stock system was "upgraded" from the stock system on the 10v, which in Europe does about 200hp.  So, the jump 200 to 217 needed the extra; I don't think Audi anticipated chips.

The Aux. radiator would have to be provided due to foreseeable(Chips, +HP,
tracks etc..)use of the vehicles engine. So it may not be merely a case of
over engineering a design, just protecting it going forward.  My intent is
to replace the main radiator with a metal/brass tank one, then solder on the
correct nipples that go to the the aux. radiator, but why do that if you do
not have to. In New England climate, AC does presently work. I could get the
lower temp T stat, and the fan may run alittle more as a result.   

 Thanks for response Gregg

You might also need to give up aspirations for running the A/C. What 
kind of summer climate is typical in your area? Northern Cailfornia, 
OR, WA--give it a shot; but if sub-tropical or desert regions--could 
be trouble, even without A/C.

Is the aux. rad. also one of Audi's  plastic wonders? If it's 
all-metal, maybe it can be repaired.
