I have a 2013 Mini Cooper John Cooper Works, L4 1.6L 1598CC, WMWMR9C54DT377905. When I goto CAS replacement it will come back saying not all requirement met. I have downgraded the software and tried it that way too. Not sure what is going on. Looking for suggestions or if I am doing something wrong.

Thanks

If you make cas firmware please go out and come inside coding/programming and make sure cas downgraded correct. If it is ok, go to cas replacement and change vin and frequency. To replace cas please follow this procedure.
