Any ideas what would leave this on the ground?

Evening all, I’ve been parking my car here for a long time and have never noticed anything on the ground after the car has been moved before. I noticed this large patch of white residue at the weekend, so grabbed a photo of it tonight. It’s only my car that parks here, so it hasn’t come from anyone else’s. Any idea what it is? Does oil go white like that when sitting on top of soil? It covers quite a big area under the car 😬

Definitely not oil, most likely condensation from the air-con, otherwise could be coolant or washer fluid.

Maybe condensate from the AC?

Beat me to it Andrew 😀

Thanks for putting my mind at ease guys. Oil and coolant levels are where they should be. Was worried about diff or gearbox, but condensate makes perfect sense! Thanks again! 🙏

A/c water drippage or if it was a diesel it could also be an adblue leak.

Does it have any smell if/when rubbed on fingers?
