Reset of Central Unit

I did some coding to my F80, but I don't know whether this is the cause for the issues I have.

Recently a problem started to appear. To me it seems, whenever it is really cold outside (like this morning at about 34 degrees), when I start the car the central unit (screen, navi, camera) don't boot up. The music plays, but after some time the screen displays "NO SIGNAL" and then the system seems to reset itself... this happens a few times with about 60 second intervals. This morning it took roughly 12 miles highway... after these few times the M screen shows up and it starts normally.
I had cases when it lost some settings (like station favorites, split screen), but this morning those were kept.

Has anyone ever experienced something like that? If yes, any suggestion how it can be solved? I will ask for a dealer appointment, but in case it is due to coding and I will redo the coding after the dealer inspections I'm afraid that the error will stick around...

I really appreciate any input on that topic! Thanks!

For reference, I coded the following things to my F80 (separately by area):
FEM_BODY --> 3110 --> ASP_BEIKLAPPEN_BEI_KOMFORTSCHLIESSEN = (werte=01)
FEM_BODY --> 3110 --> ASP_AUSKLAPPEN_NACH_KOMFORTSCHLIESSEN = (werte=01)
FEM_BODY --> 3053 --> KOMFORT_SCHLIESSEN --> WERTE = 05 (Mirror Fold Delay = 0.5 sec)
HU_NBT --> 3001 --> LEGAL_DISCLAIMER_TIME = kein_ld
HU_NBT --> 3001 --> MACRO_CAM_LEGALDISCLAIMER = kein_ld
HU_NBT --> 3001 --> MACRO_NIVICAM_LDISCLAIMER = kein_ld
FEM_BODY --> 3060 --> ESS_AKTIVIERBARER_AUSGANG = bremslicht
FEM_BODY --> 3070 --> OVT_BEI_RUECKFAHRLICHT = aktiv (Tuergriffbeleuchtung bei Rueckwaertsgang)
FEM_BODY --> 3040 --> CLM_UNLOCK_KL15OFF_AFTER_PIA_AUTO_LOCK = aktiv (Automatische Entriegelung bei Motor aus)
FEM_BODY --> 3050 --> FH_TUERAUF_STOP_MAUT = nicht_aktiv
FEM_BODY --> 3053 --> KOMFORTOEFFNUNG_FB = aktiv (Fenster oeffnen via FB)
FEM_BODY --> 3053 --> KOMFORTSCHLIESSUNG_FB = aktiv (Fenster schliessen vie FB)
HU_NBT --> 3001 --> HUD_TURNSIGNAL = aktiv (Blinker in HUD)
HU_NBT --> 3000 --> NAVI_AUTOZOOM = aktiv (Auto Zoom bei Abfahrt)
ACSM --> 3000 --> Initialwarnung_GWF_IW = nicht_aktiv (3-Gong nach Autostart)
