Touareg V6 TDI Coolant leak loss behind oil cooler engine valley

Hi

I have stripped down my Touareg late 2007 3.0 V6 TDI altitude to repair a coolant leak in the engine valley.

Took out inlet manifolds,fuel pump,egr, oil cooler/ oil filter housing ,etc, etc, drained coolant AND IT STILL LEAKED water around the area outside the oil cooler.!

It is leaking out of two holes i found below the turbo location even though engine is drained (Holes circled in red in photo.)

Any help, advice would be appreciated as I am baffled !

Thanks
