I had a couple of small issues with delivery of my IX40 and the dealer kindly offered to send me the BMW luggage net to say sorry. Its looks pretty useful to prevent things rolling around in the boot and folds small to stow away in the under boot storage area where the charge cables can be kept. Took a few photos for those interested, including the packaging as I guess one of those numbers is the part code. In the main photo I've got my work bag, which is mid sized, but the netting is stretchy so it can be used to hold larger packages too. There are 4 of those hook in the detail photo, one in each corner of the net, that each connect with the restraint points built into the boot.
