No clues to price and also no idea if it will be a "dealer fit only". I thought the link may be a problem - parts.bmwgroup.com still had me logged in despite closing browser windows. If you want to see the link then go to
http://www.bmw.com/com/en/owners/acc...catalogue.html for login instructions (I think "en" in the link is correct, "us" for you? but you can get there from bmw.com > owners> Electronic parts catalogue.). If the login doesn't work check for a browser message about allowing Java to run and it may also open in a new browser window.
