Car won’t start! Need help!!!
Update 4/24/24
-Further investigation linked to the 2 resistors on the FEM and KOMBI -Will do a termination resisting test through CAN-hi and CAN-low Update 04/17/24 -Retested the fuses with a meter - all were working -Did a software reset option from the secret menu in the cluster - all modules are responding now -I connected the battery to a battery tender overnight - battery is 12.4+ V -Looks like the error codes from MHD pointed to DME and powertrain physical wiring fault -ISTA shows a bunch of other codes (even after I cleared them, they still came back) https://drive.google.com/drive/folde...usp=drive_link I was working on the dme and might have shorted something. The car doesn’t start anymore. All fuzes are good. I also unplugged the battery for a few hours. I got 2 codes: CDA840A - DME: Powertrain CAN: Communication fault CDA683 - DME: Powertrain CAN: Line fault/electrical fault Appreciate if someone can chime in and give me some suggestion on where to look.

It's a 2016 340i. I did a software reset and now all modules are responding but some still have faults. I also checked all fuzes, all good. Car is still not starting.
