Johan - It seems that this piece would be too thick to fit between the wood dash tray and the metal support. BMW may have made an incorrect part (see paragraph below). The attached photos (72 CS) show very thin pieces of foam scattered about at locations where the wood touches the adjacent metal - and not one continuous piece.
As an aside, I know that the new foam BMW provides for the toolbox interior is also way too thick. It was around 18 mm thick and firm, when what was needed should have been around 4-6 mm thick (and soft). Actually it looks just like the foam in your photo (with a peel and stick backing).
