I had this. About 300mls every 120 miles. I had my EGR done but I was advised to see to get the charge cooler done. Get them to do the charge cooler, it's next in line for internal coolant loss.
If that doesn't sort it your looking at head gasket or cracked head. Other signs of head issues include the mayo in the oil (however the long filler pipe is prone to causing some of this, I cleaned mine to see if it came back) also a pressure build up in the morning or when cold after use when opening the expansion tank/filler tank can be a sign of head gasket/crack.
I have read others end up with very small fractures in the head with no other symptoms though so it's a tricky diagnosis.
I also did a Millers oil check which confirmed I was losing coolant internally, I guess that's good to know not essential.
Good luck
