How to Write / Flash a Siemens EMS 2K in a Mini R53

**Butch** · 28th August, 2020, 02:27 AM

Hi everybody, I try many ways to flash in boot mod my ems 2k with Galletto 1260 cable (in car OBD and on bench) with no joy. I grounded pin 28 on 29f400bb, with and without 1k ohms, for 5 , 10, 15 sec and nothing worked. Is there anyone who can explain me the right way to connect the ecu on the bench and how to proceed. I 've just been able to read via OBD and on the bench so far.
Thanks !

Any luck with that? I have the same issue with trying to write to the DME. I have found the pin that puts it boot mode. I think the Galletto just doesn't work with the DME.
