hi friend

now no communication via obd

i listen relay from BDC

what is way to repair BDC ?

[Manta1600]

write the original eeprom and if still don't have comunication by OBD buy the same BDC and reprogram it with ISN from the engine ECU

If the car is with manual gearbox also must renew the steering lock

i listen BDC cliking but no way to ignition ON car
no warning ligth
no lamp
ventilation working

no communication with car via OBD

i have backup coding read via OBD ( file 20Ko so not eeprom 95256

i suppose boot from FEM/BDC is dead , what about your opinion ?

crash wanted add new key via obd without unlock BDC :beheaded:


in autel intrusction i found strange instruction to repair it , saying :
unsolder eeprom > eeprom in socket on programmer + socket connedted on BDC circuits BUT BDC is pluged in car ? because nothing about BDC alimentation on bench

[Manta1600]

Check if you have conection on the bench

if you dont have conection on the bench this BDC can't be repaired and must buy new one

here eeprom 95256 after crash , if anybody can check if corrupted or ...

[Manta1600]

but maybe is better to call someone that can sort out all

I don't think that you can do it and only will waste the time

[peko]

I Think test made bench cable here, i have all

but i check lot of cable same as your link, and any have buton on/off others no ...

but i am not sure repair success, if anybody can confirm data from eeprom not corrupted
