BMW ME 9.2 Crashed

Hi folks,

I have Bosch ME9.2 from E87 116i that failed during update at dealer. Car cannot start. Over BDM I could read eeprom and Micro, but flash cannot be read, it throws cheksum error. As I couldnt find same number flash file, I found BDM read from same car, N45 116i engine, manual transmision. If I compare Micro files from mine original and from other ecu I see there are also diferences in files, mine ori has much less data containing, is it possible that it was damaged during flash also?

Now I have few questions.
-ISN and VIN are stored in flash also, can this flash be virginised?
-mine eeprom seems original so does it also need to be virginised if flash is virginised?
-can you check if my original micro is also damaged?

Here I post both files, Micro and eeprom from mine failed one and full BMD read from another ecu. Original ecu numbers are 0 261 209 036 and I used BDM for flash from 0 261 209 085. Now on BDM VIN is detected from that flash and old one is gone.

External flash anyway should be read with BDM100, if not - something is wrong with it. Try to read it with other tool (KTAG).

Hello I've got full bdm read with CMD

Flash is write protected!!!
Pay attention!!! 3.3v on pin 53 of 28f800 open up the write protection.

File you post is not for this ECU. Also there is no WP for this flash, only for E46 series with same ecu as far as I know. This is from E87 series and I wrote it with KTAG over BDM without problems.

some 9.2 have write protection on e65... just dealt with this on a car

yes I know, but mine doesnt. So i would need virgin file and than make cas - dme sync

Bump please

Hi,

I have eeprom dump from CAS2. Is it possible to match ISN from flash ECU and CAS?
