BMW F44 MRR change after crash FSC issue
Hi guys,

I have an F44 BMW with front crash the MRR was changed and I have to adapt it to the car.

I have a FSC repair pack for the car I am putting the FSC for MRR it is accepted for a few minutes (arround 10 minutes) and everything is working well no DTC and after that period of time it is rejected.

After storing FSC:

Code:
MRR[DiagAddress=33(0x21)]
WBA11AL0007F95832
RootCertStatus not available
SWSigStatus accepted
SWTApplications
----------
AppID 329(0x149)
UpgradeIndex 1(0x01)
SWTType SWTclassic light
FSCStatus accepted
FSCCertStatus not available


After 10 minutes:

Code:
MRR[DiagAddress=33(0x21)]

WBA11AL0007F95832
RootCertStatus not available
SWSigStatus accepted
SWTApplications
----------
AppID 329(0x149)
UpgradeIndex 1(0x01)
SWTType SWTclassic light
FSCStatus rejected
FSCCertStatus not available

I have these DTCs after:

Code:
RESULT:    2 error in error memory !

-------------------------------------------------------------

0x022103   Externe SWT-Prüfbedingung nicht erfüllt

   Testbedingungen erfüllt
   Fehler momentan vorhanden und bereits gespeichert
   Fehler würde kein Aufleuchten einer Warnlampe verursachen
   This is an event DTC. This ecu is NOT RESPONSIBLE for this error entry (DTC).
   (E.g. wrong or missing network information.)

Error code: 02 21 03 2F
-------------------------------------------------------------

0x022104   Interne SWT-Prüfung fehlgeschlagen

   Testbedingungen erfüllt
   Fehler momentan vorhanden und bereits gespeichert
   Fehler würde kein Aufleuchten einer Warnlampe verursachen
   This is no event DTC. This ecu IS RESPONSIBLE for this error entry.

Error code: 02 21 04 2F

Does anyone know of to make the FSC permanently accepted.

Thanks

RE: BMW F44 MRR change after crash FSC issue
I already have a repair kit and loaded it, it’s accepted and then after 10 minutes it is refused.

Was it a new MRR replacement or used?

RE: BMW F44 MRR change after crash FSC issue
It was a used one, I think he got it online. I got the car only for adaptation

RE: BMW F44 MRR change after crash FSC issue
If the MRR has newer FSC than the ones in the repair pack you are screwed in lack of better wording.

The ONLY way to use second hand parts is if they have OLDER Fsc´s than the original car.

(maybe could work with some type of emulator)
