Title more or less says it all. When we take the Audi just about anywhere when it's warm out there is a puddle of evaporator condensation water under the car after it's parked for a bit. I have yet to see such a puddle under the 550i leading me to think that the drains might be plugged with goo (tech term). Plus I get a little musty smell on startup some days.

I'm going to be under there in the next week or so for an oil change so I figured I might as well make sure the drains are clear....where the hell are they?
