Bmw Edc16c35 immo problem (st 95640) 2006 320d 163hp

[kptuning]

St 95640 was damaged so i order New one. Have readout from ori eeprom and prog this to new eeprom. Car starts and run Nice. Day after it does not start. Diagun says internal error 16 in ecu and cant id with flashtool through obd. The New eeprom is st 95640 like the ori, but rest of numbers on it dont match. Does this matter? Do i need identical eeprom? And/or do i need to resync dme (ecu)?

Ecu is ori. Had crash when tuning by obd. Removed ecu from car and fixed it.

new eeprom

Ori eeprom

[rrr86]

i think eep is good and suitable

the point is that you need full bdm read to recover this ECU

the cpu content may be corrupted

the cpu content may be corrupted

But why does it work like a charm the first Day, and wont start the next?

[kptuning]

apparently you do not do it right
and therefore works one day

So what im doing wrong? Should be simple? Ori eeprom dump in ori ecu. I thinking my new eeprom is the problem, but im not an Expert :tears_of_joy:

[kptuning]

Still starting first day and not next. eeprom type looks like have nothing to say as long it is 95640. Can someone tell me what is not matching in eeprom and flash? Please help !!!!

If you had error when tuning through OBD then why did you even touched the eeprom!????

Because i didnt get read or id on desk or with bdm. After buying a used ECU i got the old one back to life. Look like i have ~~~~ up something in the flash. Because after some hours in car eeprom rewrites and dont start.?

[kptuning]

[kptuning]

This is fresh full readout with byteshooter. Can someone please help get the flash matched to eeprom?
