XZBMW  07 BMW cas2 crank no start after generating key
2007 bmw m5 with CAS2, car working fine before but wanted new key so using CGDI generated and added new key same way ive done countless times and now car crank and no start. i tried disconnecting battery for 30 minutes, fully charged battery, nothing works. i don't get any manipulation errors on cas. only errors i get is DME 2798 when i scan using inpa. i tried syncing with ISTA and nothing, i get the following error when i try to cas-dme sync with ista under service plan:
- An attempt was made to start engine
- Break in DME voltage supply
- tester communication with DME control unit faulty

tried for hours to sync, nothing seems to works and i cant find anything online, any help highly appreciated. here some screen shots i took.

Have a similar issue with f07. Also was looking cas issue but in the end was an engine relay faulty.
Take attention on car wakeup click sound on opening after it goes to sleep mode
