ccruzz, If I were you, I would clean, degrease power steering rack, hoses, etc to make sure it is deed just the hose leaking. See link from Audizine forum below for instructions on removing power steering hose on Audi A4. 2nd link is for rack removal. Good luck.
I hope this helped you out, if so let me know by pressing the helpful button.
