Water/fluid from under the car

[A4B6Cab]

bear with me as this happened when the mrs was driving. she stopped yesterday in a multi story car park as she pulled out to chat with her sister, long story short, our A4 Cab 3.0 petrol was sat idling for about 20 minutes while they gassed. when she got back in, she noticed 'water, or watery stuff' running out from under it. drivers side, engine area, from behind front wheel area apparently.

didnt bother to look, so drove home 5 miles and parked up. i checked all fluid levels last night, all OK. apparently it was a clear fluid

any ideas what it could of been guys? ive checked header tank, washer reservoir etc but nothings lost any fluid. heating was on it the car while it was ticking over, not sure if that makes a difference

sorry cant be any more descriptive, but this was my missus after all, so the info I have to go on is actually better than I'd of expected

Condensation from the air conditioning drain possibly exacerbated by all the hot air from gassing…
