BMW part # 36119058635. It's not in the ETK. Described as "7-ALLOY RIM" and "parts group RI weight 5.40 kg". (The weight may be incorrect as that is less than a 14" basketweave or bottlecap.) Update: enquired with BMW dealer and they confirmed it's NLA and they don't have a diagram or fitment information for it. Still curious what it is though. Perhaps the gold or white basketweave?
