I own a 2010 Cooper S JCW. Unfortunately there isn't any service manuals for these vehicles. I ran across a site a week or so ago and did not bookmark it. You have to pay $30 dollars a day to access it but it is suppose to have all the Service information, TIS documents, etc. Does anyone know the address of this website?

 

The website is: http://www.minitis.com/

If you don't need the very latest changes or features unique to a 2010 JCW, the wiring diagrams here: http://www.bmw-planet.com/diagrams/release/en/ will probably cover almost everything you need. Also the cheap TIS discs on eBay for 2007 R55/R56 are still very relevant to most of your car.
