Tried to fiddle around the rear arm rest last night,
@Simon968 but didn't found any dismantling points.
Front lid internal cover is easily removable, not the rear one.
As for the front one, if someone is looking for a guide how-to take the lid leather part off, scroll down and follow these steps: (well, not all of them but you'll see why)
Once you lift the lid up, you'll notice it is divided in two parts 2/3 and 1/3. In between of them, mid width, slide flat metal piece and lever it down. This should unclip middle clips
This is the 2/3 cover part from inside and marked two middle clips with red arrows
DO NOT ATTEMPT TO UNCLIP FROM THE TOP, BY THE LOCK
Once middle is done, move on each side and start unclipping the cover upwards. There are 3 clips along each side of the cover, marked with blue arrows on the first picture.
When you're by the 3rd clip, hold the top edge but the lock so it doesn't move. There are two plastic hooks that easily break. Circled in red
I did the mistake, didn't hold the edge and started to unclip from the top and hooks broke off. Glued them together with proper plastic glue.
Once the third side clips are done, gently slide the cover down to unhook and release the cover from the lid.
This reveals one more clip to be pushed (marked with red arrow)
and the whole leather part of the lid can be slid down (down as you see it)
Reverse order to reassemble it.
I took it off to re thread the leather from Black to Red
Matching now with gear gaitor earlier done.
Hope this helps anyone.
Good luck
