We received one feedback that BMW f30 2014 can not write back the info to the 95256 chip in the fem / bdc itself via godiag fem / bdc + test platform
Here is the procedure:
VVDI PROG read the data
VVDI Key Tool Plus process:
The first step: Backup the code
1. After connecting the FEM/BDC system on the car or platform, back up original coding file through OBD
2.After pre-process starts, it is recommend not to close this page
2. Load original EEPROM and prepare service EEPROM, write service EEPROM data to 95128/95256 chip
3.Restore FEM/BDC shell, provide +12v and connect OBD
From the pic, you can see the connection is bad.
Here is the engineer reply:
The pin contact is not good, not the wrong connection. Clean the pin gray waterproof glue then check.
