1998 740il with 63M miles...I am new owner. After Phase II service, intermitent oil leak from engine...does not appear to be engine, brake or power steering oil. Light color, blue/green tint...transmission?

Could it be windshield washer fluid.
I had a leak and that is what is turned out to be. Don't know yet if the resovor is leaking, cracked or if I just overfilled it.
It was blue though.

If it is oil then have the tranny hoses checked. The color should be blue

Fluid is greasy...probably not wiper fluid.
