Adaptive headlight warning, how to code away/ suppress

I have the adaptive headlight warning that comes on at startup, and I want to code it away/ suppress the error. Anyone have luck with this? A DIY would be so loved.

So far I am hearing the following 2 proposed solutions, though both are unclear, and I have yet to hear a good DIY that leads me to success:

1) simple, yet highly inaffective: change one or more parameters in the .MAN file and write it to the ECU (CAS?)
- CHECK_SMC_ERROR (nicht_aktiv)
- ALC_FAHRZEUG (nicht_aktiv)
- ALC_KLS_ENABLE (nicht_aktiv)

2) more complex, but more likely to work, change the VO/FA file to ignor the entire active headlight module,
1 remove $524 from ECU CAS, WRITE_FA to CAS
2 remove $524 from FMR or NFRM depending on which you have, WRITE_FA to FMR/NFRM depending
3 write blank MAN file to CAS
4 write blank MAN file to FRM/NFRM

When I try method 1 it writes but does not remove the warning
When I try method 2 I get this error when I try to write to FRM: FA_AUTRAG: ERROR ECU CONDITIONS NOT CORRECT OR REQUEST SEQUENCE ERROR

If you have success at this or suggestions please post, DIY we will be forever in your debt

After this changes did you recode your modules? CAS, NFRM, LSCM, RSCM? Don't use blank man, just use EXPERTMODUS profile and select ECU, then SG_CODEREN and click EXECUTE JOB.

My error is specific to the adaptive headlights, I dont have a photo of it, but I pulled the code and it says something like 'adaptive headlight module failure'

VO code out $524. That would remove adaptive headlights all together
