I will bring laptop, software, cable and my token so we can do the coding anyway - my only other requirement will be the car to code and maybe an extension lead for charging the laptop depending upon how long the session takes with 2 or 3 cars.
My plan is to show you how it is done as it really isn't that scary, then if you feel capable of doing it yourself, you can get the cable and token at your leisure in the future should you need to.
What I suggest is beforehand take a look at the F30 coding database app
http://f30.bimmerpost.com/forums/sho...d.php?t=882590 and decide what you would like to code.
