Unhappy One more M3 with increased emission. Help please!

New to this forum and already begging for help...

Car starts on all cylinders but within 5 seconds goes into limpmode.
Problems started after replacing my battery. Did register the new battery with BT Tool.

Getting ABS, DSC and increased emission on the dash.
Following faultcodes are present:
CDB4, CDB8, CD9D, CD9E, CDB0, 2B36, 2B37, 2B39, 2B3C, 2B41, 2B43, 2B44, 2B46, 2B49 and 2B4E.

Following has been done to the car without any success.
New sparkplugs
Moved Coils around and misfire doesn´t follow any of the coils.
All 4 O2 sensor have been replaced.
Changed fuel in the tank just to eliminate that bit.

I have a reading on the pressure from the HPFP but unsure about what values is normal.

Been struggling with this for a couple of months now so any help or leads are more than welcome.
