Hi guys, after trying to read out a pin code with FVDI , same problem as usual, car lost all power , no ignition anymore and no com with module 5 EZS. Tried pulling fuse, reboot with battery off but nothing. I removed the module from the car , read the MCU flash + eeprom with XPROG . Flash seems to be OK, but eeprom seems to be corrupted !? Even the VIN isn't complete when opening the dump as if some bytes have changed ? I've seen a topic on this forum where in the eeprom bytes have been swapped around ... It isn't really my case but something happened ...
Car VIN : WAU ZZZ 4F97N001643
Any pros about this topic that could give me a hand on this ?
I've posted my flash + eeprom read out with XPROG.
have a nice day !

hi guys, just for an update, i managed to get the car working again thanks to Bobble's precious help
eeprom and flash were corrupted. But now car is in component protection mode. Got to find a solution ! thanks I saw that ODIS online car do this, but it will be tricky to find someone with access .
