Weird Oily, Odorless, Colorless Substance Leaking on Garage Floor--1998 E300 DT

I need some help identifying a leak under my 1998 E300 Turbodiesel. There is a long oily, odorless, and colorless trail left under my car overnight. I thought it was water until I felt how slick it was. No diesel odor. No black diesel oil color. Anyway, today the check coolant light came on which really puzzled me because coolant isn't greasy is it?

Any suggestions would be great!

Happy Holidays!

Coolant is kind of greasy. The higher the ratio of coolant to water, the greasier it is.

Well if the check coolant light came on, and before starting the car I would check the coolant level.

If needed, I would add distilled water. Then with the hood open, start the car and while heating up, run the heater on high and start looking for leaks.

You also have a good holiday season!!

PS: Regarding the long slime line, that could have been the result of what you ran over earlier in the day!!

The belly pans make detecting leaks and sources pretty tricky. You can wash the car in the morning and in the evening pulling on steep driveway you will have good amount of oily water coming out of the pans.
Check the coolant level for sure and start with taking a look at the water pump and radiator hoses.
