Ok so I have some more pics and a possible part number It now looks as if I can access the 2 bolts to the rear and the screws to the front to remove this completely, won't get a chance now will the weekend. Hope these provide some insight of how the armrest is fitted.
The part number may only relate to the cover I removed but it could still provide a reference to held a dealer find the other parts/
Wow, thanks for ripping your new car apart for me
That is ideal. I can clearly see how it all plugs together. I fear that part number will be for the back plastic cover but it gives me something to go on.
I'll be back after some serious googling.
