This is funny. I've actually spent the last couple weeks trying to get that specific part # from BMW. Here is what i found out.....
The part number is correct. 7215 8321611 Retail is around $150
This is the official BMW Tow Strap. BMW isn't allowing any US dealer to import them. I've had three different dealerships try- paid for it twice. I even have a connection (my sister) in Germany that was going to get me one until I emailed Nate @ IND.
You need to make a custom bracket for this to work on your car. Apparently, it is a big pain in the @ss. I then called Turner Motorsports and they have 80 of theirs in stock. Theirs is a direct copy of the one that came on their E92 M3 race car that they had imported. It bolts right in. They don't offer any slit on the stock tow cap. They just remove it and pull out the tow strap.
I would just order it from Turner and be done with it. If you want one from Germany, I'm getting four. Two are already sold
