My supervisor at work has a 2015 5k old fiesta titanium ecoboost, asked me the other day if i knew why it would smell of gas, and the header tank was bubbling. I said about possible coolent leak but he said it all seems ok. Ill have a look tomorrow.
Also how do you know about the focus issues as another chap i work with has a 13 plate 125bhp focus ecoboost.

I have the 2.0l mk3 focus st ecoboost, any issues with them at all?
I have a slightly noisy pulley on the engine but no problems as such. Its on 31k.
