The car has been checked and no leak was found,but its going back this week as the coolant has been dropping level. But lets see what they say when they check the car on tuesday.

Having the same issues with 1.6L Ecoboost in my Fiesta ST, split its header tank recently so replaced the tank and all its hoses with new genuine items.
Rough idle for about 20 seconds on cold start when its been sitting, a bit of white smoke out the exhaust at idle when at operating temperature that comes and goes and I'm losing coolant slowly - can't see any leaks.
I reckon its the dreaded block issue on mine, next thing for me is coolant leakdown/pressure test and bore scope in the cylinders I think to see.
Hopefully yours isn't similar, not sure if 2.3L ecoboost is open deck like the 1.6L and has the stupid cooling slots.
Mines got 230,000km on the clock now.
