I was thinking about doing the same but heard that when BMW does a systems update (wirelessly over the air now with i drive 7), all coding is lost and needs to be redone. I don’t want to have to pay to have the coding redone. Ideally looking for a solution that lets me code myself. Bimmercode and Carly would have been great since I don’t have access to e-sys but I guess the g20 is too new for it to be supported.
How much did you pay and what did you have coded?
