A thought, there has been a lot of discussion on here about what functions are available by re-programming the BSI. (one touch windows, speeding alert etc)
Could you use your contacts to find out what is available and how to do it (i'm not suggesting that we all reprogram our cars ourselves), some people have had these chanegs done and some people are being told by their dealer that its not possible.
Sorry for changing the course of this topic. But it just occured to me.
