Technical Relatively clear slimy / viscous liquid under the engine -> What's this?

[newabarthdriver]

Hello!
Since five days I drive a Stilo Abarth (2002). The car is just great.
But there is a problem, and I do not even know wether it is urgent or not.

Pretty much seems to emerge a liquid to drip in the middle at the height of the front axles. The liquid is relatively clear and has a lubricating characteristics (shoe sole is then very slippery).
Condensation from the air conditioner can't be the issue, since the resulting patches are also still visible several days later.

I can not make any sense, because I am a layman. The fluid levels all seem to be fine. The tanks in the engine room are ok and the oil level indicator at the very top.

The appendix contains images.


Thanks in advance!

try to wash it with only water..
if it goes away it might be cooling fluid.
else... diesel/gas... gearbox oil

Does it smell like cat urine? If so, gearbox oil. Only other thing I can think it might be is brake fluid.

Ok. The case is solved.
It is engine oil... The garage spilled some and the dripping rest is trapped in the undercoat.
