At some point during my ACC retrofit, I managed to seriously screw something up. I only have power to seats, lights, and radio screen. Everything else is dead.

At first my issue was believed to be a poor solder connection when tapping PT-Can. After fixing that issue and verifying correct resistance via multimeter (target 60ohms), I still have no power. No data coming from OBD2. I dont have enough experience to know where to troubleshoot next. Send in CAS, replace JBE? I'm not sure.. Battery is new also.

Anyone with electrical expertise on these cars I would greatly appreciate your help. TIA!

you might blown replaceable or nonreplaceable fuse in fusebox or jbe
so you have to check all removable fuses and if that will not help, then you have to replace fusebox with jbe

OBD 12 volt line would be the first thing to check .
I believe there is only one fuse between that and the battery .
Saying no power mostly is to vague.
Take actual voltage measurements.

I wasn't aware of having to replace fuse box with jbe if I don't find an issue, thank you pt.

Also unrelated- your alarm retrofit has been working perfectly since I installed it years ago. Thank you.

I'll look into that today!

Items currently not working:
Key
Start button functions
Kombi (backlights work with parking lights, display is off)
Audio
No classic "bimmer noises" (clicking relays, whirring from cd player etc)
OBD 2 data (obd plug still emits power)

Unreal. Disconnected my remote start and Im getting some functions back. Key fob still doesn't work but its too early to confirm if memory wiped or theyre both dead from sitting so long.
