I will start by saying dont try this on your own unless you have a resonably good mechanical knowledge and a set of smallish Torx bits - oh and patience and thin arms and a large vocabulary of swear words (I only have the last attribute).
I was one of those who, in the mad rush to order my car, didnt notice the car didnt come with - then didnt have time to add - front fog lights.
The car arrived and the silver plastic fog light shaped inserts were not doing anything for me or IMHO the front 'look'of the car. I managed to get a set of fog lights off Ebay and was happy once again
Boy was I in for a shock. I will take this opportunity to apologise for not having any photos of the job as it progressed but if I had to do that as well I probably wouldnt be able to write this as there is apparently very little movement in a straightjacket.
I decided to do this the easy way (Oh really!!) and not completely remove the front bumper. I really only wanted the fog lights for 'show' and didnt intend to ever wire them up. On my Pure (Think Dynamic is the same) start by pulling firmly on the black semi circular arch trim. It will pop off and can be easily refitted. There is one of those push in type plastic fixings which holds the arch liner to the front wing (the wings on our really expensive cars are plastic by the way !). Both sides are the same. The arch liner can be teased out from behind the wing and is flexible enough to get a thin arm (or a fat arm - if you can stand the pain and the after-look which resembled a serious self-harm effort) into the gap, pop out the upper and lower black plastic trim pieces and unscrew the 3 Torx screws (size 25 I think).
You will find that if you start on the nearside there is nothing much in the space and the plastic insert can be removed reasonably easily. The fog light can be manipulated through the same gap as your arm and is fiddly but can be screwed in with a bit of patience.
The offside is a whole other ball game. Fixings/arch trim are the same but the windscreen washer reservoir takes up most of the area behind the fog-light. Had to release the single fixing holding the reservoir to the chassis and the support on the bonnet slam panel but still had to hacksaw off the lower fixing on the silver trim panel before I could get it out. I then took the green screw fixers off the bumper and transferred them onto the fog light which can with a bit of gentle forcing, lots of swear words for lubrication and patience (you wont have any left by this time) will eventually go back in and the screws were re-attached from the outside rather than the inside.
Took about 2 hours - looks great - but I filled the swear jar and both forearms looked like Id had a serious go at self harm.
