UPDATE : OK , so I had a good hunt about for this ODB2 port and found it myself
For others looking , find the 'foglights' switch panel at knee level on the door side of your steering wheel. On the top edge next to the steering wheel is a 'Phillips' head screw , undo this (it doesn't come all the way out). Next use the small compartment just below the switches to pull on untill the panel opens (it opens at the top and is hinged at the bottom).
If at this point you cannot find the ODB2 port then you should under no circumstances plug anything into it
This is the same location where you will find your interior fusebox
