While troubleshooting my AC issue (thank you all for help, I am ordering a new aux fan) my car refused to start. It is cranking just fine but will not start. The foxwell has no pertinent codes (just the aux fan code in the DME and nothing else other than some light codes).

Symptoms: car worked last night. Today I fired up the foxwell again and scanned codes and disconnected the aux fan cable trying to check for voltage. I tried resetting the oil change indicator but it wouldn't let me. I looked at the EWS in the "service" page, as well as a few other menus, but didn't do anything with it. Then I tried starting it and it won't start. It turns over very strongly and continuously and doesn't throw any codes other than the aux fan.



From searching, I think I've determined that if the immobilizer had tripped or faulted, that it wouldn't turn over -- it would disable the starter. Is that a good assumption>


Any help would be appreciated. I am trying to find a manual or guide on how the BMW EWS IV works, but can only find up to EWS III.
