Rear oxygen sensors disable E92/320i/N46

[Jitter]

Hi !

I've heard that most of E series has "undocumented" function for easy disabling rear O2 sensors (if CAT is deleted for example) to eliminate 002А73, 002А77 errors:
- disconnect lambda
- programming and coding as usual (ista/p for example) to raise integration level.
- DME will autoresponse that lambda is disconnected and disabling it during coding stage.
- thats all, but if you connect it again - they will enable again
- you can disconnect signal wiring and leave O2 sensor heating connected


Is this method working ? Of no - how it will make right
