Help locate an oil leak
I've jacked her up and pulled the splash guard, also pulled the air filter, I don't see anywhere on the engine that this oil is coming from, everything above the wet subframe is dry.
So the second picture is where the leak is exiting the car, at the lower control arm bush drivers side, and the first picture is the accumulation of oil after about 1 minute of runtime, its a considerable leak.
Does anyone have an idea what would be leaking on the engine to come out at this spot on the subframe?
It's an 2009 XF-P with 145,000 miles

My leak is absolutely motor oil. I didn’t know oil left the engine, I thought the cooler was built into the filter housing and the cooler used coolant cool the oil.
Is oil pumped to the radiator like the tranny?
Or maybe I’m completely wrong and my tranny fluid smells and looks like motor oil, that fluid is the original fluid, could it be that it doesn’t smell like tranny fluid any longer?

Zf tranny fluid looks like motor oil. Its a honey brown color.
Take a second look next time you're under the car. You will have to peek in, past the fan shroud, to see the trans cooler lines going into the radiator. Mine was leaking where the steel line connect to the rubber hoses.

The location you're talking about is spot on, it's the only place above the leak that something is wet, but I've been so certain that it is motor oil leaking that I didn't investigate the trans lines further.

Doesn't even smell like transmission fluid. I even thought it was oil. But while doing a transmission fluid change, i discovered the fluid looks like motor oil and it doesn't smell like conventional trans fluid.
You have get a light and shine it in the area directly in front of the radiator fan.

I was just under my XF again, I cannot pinpoint the leak without removing more stuff. At the very least I will need to remove that cowl under the bumper, then maybe I can see where its coming from with certainty.
I do think you're right sv8, it's one of the hoses coming from one of the coolers up front, which one isn't easy to spot, motor oil, tranny fluid, I'm simply not sure anymore..

Just want to give an update, it was definitely the transmission lines leaking. I simply cut off the compression fittings, replaced the rubber and added 2 hose clamps at each joint.
