This means FEM is in programming mode or is not responding, please check if you can see gateway and cas in the programming list with valid hardware and software numbers. If all are --- then it is not responding. If some have numbers then nothing is serious. Try to flash zgw first, then cas.
If it is a brand new, you need to fill the FA, the only method ( other than online with BMW) is to read FA from old fem and write it in this one, by FA manager.
Also it will be great if you try to check if it can show some fault codes ( both cas and ZGW)
