If only happens after reflash,confirm soldering and clean very well all contacts and pcb.
Files could be damage,backup,post it,jnoroeste

You can read en write this ecu with mpps or fgtech in boot

if fan starts the ecu have no contact with eeprom

try this original file

Happend to me.
I transfered eeprom, and wrote flash on secondehand ECU.
Possible used wrong voltage pin out in my case.

I think ecu broken 100%

Best way to read this ECU with boot mode
I will buy an other used ecu I will change 5p08c3 eeprom
I hope car work now


Thanks for help
