2001 S80 T6 coolant leak behind engine on passenger side - b

[T64me]

Trying to help my friend repair his 2001 S80 T6. When we added coolant to the reservoir it drained right out on the ground. I thought there might be a crack in the reservoir. I removed it, tested it, and it holds water. I put a funnel into the hose that attaches to the bottom of the reservoir. As I poured water into it the water poured out the driveway. I followed that hose behind the engine. It goes into a metal tube that goes into the turbo area. I could not see the where it is coming. Any suggestions where I should look?
