Clear Fluid under Car

[Ri Orus2]

Just a quick one. Got the car out for a warm up and pootle around the village after a fairly lengthy winter layup.

Spotted a bit of clear fluid on the floor, in the garage, under approximately where the rear diff is.

It doesn't really smell of anything other than a slightly metallic tinge, so its definitely not fuel.

My thinking is its condensation from the recent warm weather / cold snap over night as it was only about the size of a 50p piece. Garage is unheated.

Any thoughts as to whether it could be anything more important?

Thanks in advance.

Probably condensation in the exhaust dripped out of a joint?

Definitely the rear diff?
