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

**kptuning** · 12th August, 2018, 03:57 PM

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)?

HELP

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

Ori eeprom

i think eep is good and suitable

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

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.?
