I have 2012, 1.4 tfsi, in cold, damp wether, it too emits an alarming amount of vapour but only idle, No odour, no coolant loss.
I was concerned the first winter this occurred but it cleared once warmer temperatures arrived. Same through this last winter but now we are experiencing above 15 degrees vapour has cleared. No loss of coolant with mine. I remember doing a google search when I first experienced it … seems to be pretty common.
