Hi Richi,
I think the parts should be now available to order. Bmw.de put online the accessories pricelist. Some parts are listed and you can find their parts numbers on the pricelist. Some parts seem to be already available (since April), other (most of them) will be only available from September.
Here is the link of the Pdf pricelist. Pay attention the price are valid only until September 2014!
