Large puddle under car over night

[h20mobius]

I too have a large pool of water that accumulates under my car ONLY when the AC is running. By large, I mean the pool becomes 3'x3' after the car is shut off.

Any ideas what this could be?

It is leaking from the center section of the vehicle.
It is not greasy, sticky, etc. It appears to be water. There is no coloration to the substance.
If it's indeed water from the AC condenser... I'm concerned about the volume. What could cause this type of volume and is it a bigger issue?
The car is a 2002 4.4i
All Fluid Levels are acceptable.
If I turn off the AC, the leak ceases


I just purchased the vehicle this week... so I'd appreciate any advice one can provide

water and it's normal

It's totally normal. The first summer I had mine I freaked out too, it was a large puddle. They said its condensation or something like that but ya, there is nothing wrong with it, it's normal.

Alot of BMW's to go to auction as lease returns. If you see one that is right at 2 years old, that's most likely the case. And they usually have some warranty/maintenance left. Then you could either bring it to get CPO at the dealer, or do some research and pick the best aftermarket warranty when needed.

Not all dealers send their lease returns straight to auction, but I know mine does and I have some friends that got decent deals on 2 year old BMW's still under full warranty and maintenance from auctions.
