EEPROM problem on ME7.1.1

[bauvaisis]

Hi guys :)

I've flashed a porsche cayenne 955 with a me7.1.1 by OBD today. Car started Fine drove nice, but once ignition was off, car wouldn't start a second time. No more communication with ECU ! Fans where on !
I've read the flash to check in boot mode, it's all ok checksum OK, but then i read the eeprom and have a doubt on it ! would someone be willing to have a look if it's all ok or needs a reapair / patch to get the car going again ?

Many thanks for your precious help !! :)

Just some news, I managed to get communication with the ecu on bench again through normal mode also (not boot) . VCDS and FVDI diagnostics can communicate ok. I flashed the dump through boot mode with fgtechv54 again just to make sure that the full writing cycle is ok and that no "programming error will appear". I'll try on the car today but if ever someone could help me out with the EEPROM FIX PATCH about this would be really thankfull :)

thanks ;)

As promised , some feedback : car starts fine again . No fault codes stored. I guess the flash written on bench in boot mode cycled the thing and ECU came back to normal ;) didn't even have to use your eeprom fix :) but thanks
