The car has had the SMG setup done again after the GPS was fitted and it went through fine without any issues. Also the clutch has been bled too. The car now crunches slightly when engaging R or 1st. When running the car changes gear perfect. Occasionally the car will skip 1st and engage 2nd so need to pull off in 2nd gear. When it misses 1st the idle will be up and down a little until the idle then steadies out. Any ideas of where to go next? Their are no error codes either. My mate has given it me back and has not even charged me for fitting the GPS Sensor and sorting the slave cylinder out as he feels bad that my issue is not 100% sorted. I am near Liverpool so anyone know of a good BMW expert who knows about SMG. Just want to get this little issue sorted now before selling the car in the summer. I do have a laptop with inpa so can do some tests or changes myself if needed if someon has any ideas.
