If it coming from that area, I would also guess that it's coolant in nature or some kind of water drain exit that was plugged before maybe, then the hose got disconnected somehow letting the water comes out???...

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

After finishing work the other day, I walked to my car (2004 C4S) and noticed a river of fluid exiting under the rear. Looking under the car, I saw that it was actually leaking nearer to the front diff. The next day, I pulled off the undercover to find the source, but everything was totally dry. The diff was spotless (the fill and drain plugs were in place). Could it be a coolant leak? I wasn't thinking, so I didn't examine the fluid itself after first discovering it. (The next day it had been absorbed into the asphalt.) However, I did notice this outlet. Is it supposed to be connected to something? TIA, Pete

Anyway good-luck finding the problem, cheers,

POST 3Original post

Sure it's not condensation from the AC condenser?

POST 4Original post

I'm with Captain Obvious - water from the AC. Had the same conversation with my wife yesterday when she thought our 2000 was weeping vital fluids...

POST 5Original post

Was it actually absorbed by the asphalt or did it just evaporate? Next time check the texture, smell and if you dare, taste of the fluid. If it was anything other than water from the HVAC drain hole, it will leave some sort of a mark/residue.

Evaporation might be a better term. Yeah, I obviously should have examined the fluid more closely. If I had to guess, it seemed to more closely resemble coolant than oil. I checked the and brake fluid and coolant levels; they were good. Therefore expected to find diff leak, but nothing there either.

POST 7 / ORIGINAL POSTEROriginal post

Would love for this to actually be the cause. It just seemed like a lot of fluid for condensation.

POST 8Original post

As Imo000 said, anything other than water will leave a residue or marks on your floor. Coolant is slippery, and usually colored (red, orange, sometimes green). Transmission/gearbox lubricant has a distinctive smell (sulphur?) and is very slippery. Oil is slippery and can smell burnt if it isn't brand new. Maybe not great descriptions, but you get the idea. Yech, taste it? No chance in France.
