Looks like your problem centers around the DTML pump in EVAP system. I’ve never had to diagnose issues with that system before but hopefully others can chime in.

DMTL won't prevent the vehicle from starting afaik. Very common issue.

I agree. The loss of communication could be an issue or it might just be a result of the battery replacement.
OP, when you say the vehicle doesn't do anything else, can you take a video? Does iDrive work / does it behave like a normal X5 except it doesn't start? If that is the case, starters are very common on those motors and that might be the problem. I second scanning for codes (plug for myself: if you have an android phone & a generic ELM327 bluetooth adapter, I wrote a free app to scan for BMW specific codes on the engine ECU
https://xoutpost.com/bmw-sav-forums/...p-android.html ). If you don't pull any serious codes from the DME or CAS, you'll need to do some manual diagnostics. Confirm the presence of fuel pressure (should be around 70 psi with the vehicle off iirc) and you should hear the pump prime when you open a door. If that checks out, I would try to probe the starter if you can get to it. Look for 12v at the large lug on the starter at all times & on the small plug when the starter button is pressed. If both are present and the car isn't starting, the problem is the starter. The typical failure mode is that it works fine and then all of a sudden you press the start button and nothing happens. No click, the engine doesn't turn, but the car behaves normally in what would normally be the "run" position.
