Sometime when I park my A4 and come back to it I will find a puddle of water under it. When I touch and smell the fluid, it doesn't seem to be coolant. I thought it could be caused from the AC condenser but it occurs when I don't use the AC. Has anybody else had this problem?

 

Need some more info - what color is the fluid, and where under the car do you see it? You could put a piece of cardboard under the engine overnight and maybe that'd help you locate where in the bay it's coming from, and that'll help narrow down the location of the leak.
