OK quick update, I found a bmw dedicated obd2 cheap as chips local to me, so fo £10 I can have a play until my icarsoft Pro arrives, step one was to clear all codes and to my surprise the trans fail disappeared from the dash, I also removed the red tyre pressure warning light with this tool, quite impressed so far, so I started it up and all gears are working, even the manual side of the box is working, the only light on the dash now is 4x4 Amber warning lights, can't seem to get that one to stay off, so I know I have a problem, but at least the gear box changes now and the tyre pressure warning light has gone
