Hello, flash with esys.

I don't have an ignition.
How can I flash it with esys without ignition?

Did you use any tool on the FEM, like a BMW Explorer, abrites or something like that?
When reading the SVT which ECUs are available?

I have tools: Xhorse vvdi2, Autel IM508

With VVDI i think its possible recover.
I just tend to have problems with some people who use a BMW Explorer or Abrites and lose a SWFL, now I've never seen both of them. but the ones I had without a SWFL were recovered with ESYS. even when I can only see FEM_GW and with corrupted SWFL.

I think you have cleaned the 95128/9526 chip in preparation for reading the eeprom. This process may have damaged the chip or components surrounding the chip

[Pedrom92]

If this is the case, you can try placing a eeprom DUMP from another FEM and try flashing again.
I already did it with VVDI and it worked.

Thanks for your support.
The error was in the Eeprom. I didn't do anything to the eeprom before, just cleaned the pins. But now it works and FEM is freely programmed with VVDI.
