With the help of Bernard today, we removed the front bumper and set about finding out the cause of my HID been blown, as its a factory HID its not a simple case of swapping bulbs in 2 minutes to get to the source, the front bumper has to come off to get the light unit out so that the back of the HID unit can be taken out and hence the bulbs can be removed. The factory HID unit extends out further than aftermarket units, and the aircon pipes don't allow you to remove it.
Heres an image of the back of the unit, anyone with HIDs will notice that the back protrudes much more than theirs, the second picture shows the location of the factory ballast for the HIDs which is below the headlight unit.
I'll be honest, its a ridiculous setup, and definitely not ideal for changing a light bulb! However, we finally got the bumper off and swapped the bulbs over to discover thankfully, it was only a bulb blown. Now the next problem, these are not ordinary HID bulbs, they are specific to FTOs, Evos, and a few more cars. The connection is totally different so you cant just go and buy a HID bulb, we found some for prices of $200, which is another joke, but then we found some on eBay for €40, obviously I snapped one up! The bulb in question is a Osram 66040 35W bulb. You can see in the photos below the connection and the bulb.
Hopefully this'll be some help to someone else who has a factory HID bulb blown, I've been looking for info on these for ages and its very hard to find it so maybe this'll save someone a bit of time sometime. Main thing is that these bulbs can be got cheaper than even camskill provide them, and that the bumper has to come off to do this job. I don't know why Mitsi did this, as if you go to a Mitsi dealer with a blown bulb, then theres a good chance, after labour for 2 men, you'll be paying the bones of €300 to €400 for a front lightbulb. It takes time to do it yourself with a mate, but it works out much cheaper!
