It is BMW part number 71106773536. It's kind of expensive, but it is a nice compact jack and lug wrench in a bag. In the E90, I stuff it under the trunk floor panel. At Tischer BMW, www.getbmwparts.com, it is $130 (BMWNA list is $162.50). I think I paid a bit less than this last year for it, but I can't recall. Go to the "shop parts" section and put in that part number. If you're not familiar with Tischer's online parts site, it is a great place to buy OE BMW parts at very good discounts. You can see the real BMWNA MSRP for parts there too (to see how much your local dealer marks up the list price).
