Model S suspect HV battery issue

[jkzfixme]

I have a '13 S p85+ heat went out and the tesla service center kept jerking me around with a rental 3 times. Nearest service center is an hour away and I have kids in daycare. All of a sudden started popping codes like crazy.

BMS_f107
BMS_w107
MGS_u008
GEW_w018

unable to drive voltage supply to low on center console battery at 18%

Tesla called me and said its not PTC , HV battery is hosed.

I thought timing was a little to suspect so I changed out the DC-DC converter, PTC heater with a gen 3, and new 12v battery in the hopes that it would fix the issue.

Now it fired back up with

DL_u014 - unable to drive voltage supply to low
GTW_w018 - Electrical system power reduced vehicle may shut down unexpectedly
BMS_u018 - Maximum Batter charge level reduced OK to drive schedule service
BMS_u008 - Vehicle may not start service is required
BMS_f107 - Service is required Schedule service.

attached are all the things from scan my tesla. Am I hosed ? HV the only way ? is there something I can do to reset ? Now I can not seem to get the charging port to unlock. It opens , but wont unlock when I click the button. = (

Happy thanksgiving !

f107 is latching error so it only needs to happen for split second to trigger
Since voltages are good now, it might be bmb board itself or intermittent connection somewhere
