This is for - 42 DDE control module (EEPROM and configuration)
I disabled this error but after that show me - 48 injection quantity regulation and BMW doesn't want to go after 3000 rpm.
I think its mechanical problem on fuel injection pump.
In measuring blocks BTDC its max 3 degrees.

Hm... try with this file, it's original one, but with different configuration.
Nothing to lose...
If no luck, try to update the ECU with WinKFP or Progman... maybe the problem is in EEPROM.

Thanks Bobo for your time to help me.

Scan the pump for DTCs (with k-line adapter on he's plug directly).
Use this program...

I can thell you exactly byt not with words you have to see it it live you have to dissasemble fuel pump completly and you need parts sometime depends on situation with pump so without parts and new set for the pump is not possible to repair.Is not simple job.
