Would a been a bit easier if you posted a picture from your car - can't see it in the link - although not 100% what you are describing?
What reg is your S4 also?

However, for a 2004 S4 there is a "Y-piece" for the axillary S4 radiator connecting the upper hose of the radiator, Part No. 8E0 265 381 (~£2.83)
PM me your email - I will send you a screen dump jpeg of the parts diagram and the various parts so you can see for yourself.
