Could be the EGR hose that connects to the oil cooler. Since you have an 03, your hose might be orange and those often failed. They upgraded that hose. It is now a blue one.

Could also be the rear side of the degas (overflow) bottle cracked at the seam of the plastic.... very hard to see there.... ya have to remove the bottle and flex it to find it.

If it is the EGR cooler hose, no, the turbo does not have to come out. Just the CAC tube needs to be removed for easy access to the hose.

Parts you will need:

Coolant hose for egr cooler - 4C4Z-8592-AA

Inner O-ring for outlet port - 3C3Z-9N693-FA

Outer O-ring for outlet port - 3C3Z-9N693-EA

A thread with some suggestions for tools:

The top part of the oil cooler is a cap. Then the tube the hose is hooked to is another part that pops out. It's snug. I just pulled that out and then pulled the old hose off the EGR cooler tube (which you can't see). Once out, you can put the new hose on the tube to see how it clicks in place with a twist. Then you know how to set it when you shove the end of the hose under the pedestal. Need to lube the end of the hose that does not have the little white marks, you can see in my photo above, lube it with coolant.
