I have a e92 that came with no key and was told it had a bad engine
Did compression on old engine, and it barely made any
Replaced engine with reman unit
DME had no coding and the engine would crank, but not start
Tried to code and sync
same result
Tried to learn new key first time programming any CAS3+
Cleared faults, reset ECU, clear faults again
read ISN do a bunch of stuff mindlessly not realizing this isnt some chysler easy crap I am used to working on
broke everything to the point of having to restore bin to get engine to crank again
no start

Removed CAS module assembly (with the ribbon cable and ignition module)
Removed DME
Removed electronics junction box module
off to the bench

wired CAS k-can to JBE
wired pt-can to JBE
both lead to OBD connector

I'm using alldata wiring diagram and there are some discrepancy to them
does the cas receive terminal 30 for power and out put terminal 15 sig to DME to boot DME?
does JBE need to be powered to allow CAS & DME to communicate?
do all grounds need to be present or only select pins for booting and programming?

old key reads locked, couldnt find a way to unlock
2 new aftermarket keys on hand

2011 BMW 328xi Coupe AWD (E92) L6-3.0L (N52K)
Manual tranmission

any help appreciated!

hi
this car most probably have msv80 dme you can connect cas and dme together using autohex and read isn from dme in isn manager option 1 and write it to cas on option2, also you have to connect key slot to cas. if you have vin we can confirm the dme HW4 CAS3.png You have insufficient rights to see the content. HW4 MSV80.png You have insufficient rights to see the content.
