Audi Repair: I have leaks in my 98 Audi A4 1.8t Quattro, windshield washer fluid, power steering fluid

Question
I have just started noticing leaks underneath my car. I seem to be leaking Power Steering Fluid, and yesterday I had my Windshield washer fluid filled and that leaked out all over last night. and besides those two leaks there seems to be a darker substance leaking in spots. I am assuming that is my oil. but when I had my oil changed the other day they said they didn't see any leaks...

I am having my car looked at today... and then I will be heading off to an Audi dealer to have them look at it too. I was wondering what the prices ranged from and if the darker leaks could be anything else?!

Answer
Difficult to answer these questions; let me know what the dealer says.  The one way valves on the headlight cleaning nozzles sometimes stick, causing all the washer fluid to leak out.  Power steering fluid normally either leaks at the steering rack or at the reservoir or even the pump... Oil leaks can occur in many places; let me know.  Jan
