Exactly so it has to be your software, since the MAN file you sent me had no FEHLERMELDUNG_CC lines deactivated.
This edited version (along with the one I sent before) had multiple more FEHLERMELDUNG_CC lines turned off and other cold and warm checks deactivated in addition to yours.
So if you are using my file and coding the FRM module and they are remaining unchanged, it is your coding setup.
I hope that all makes sense. I've never come across an LCI retrofit that hasn't worked either.
