Hi Trevor,
Thanks for the quick reply. No It's not your eyesight. I cannot actually see the leak. Yesterday, when I ran the car for about 15mins, I could see a very small amount of vapour coming from this vicinity ( marked with xxxxxxx) I do not know my way around modern cars so not sure what these components are.
I have heard EGR and water pump mentioned as possible causes but cannot easily locate them. I will go under the bonnet again and try and get some pics with the cover removed
