And I traced back the lighting system's circuitry and concluded that it's kind of rudimentary in its construction & modus operandi.
Meaning, there is no specific sensor monitoring an outage of each light/LED, it's more so just the Body/Front Control module monitoring the direct flow current, which based on its set algorithm, it indirectly triggers an error (or not).
The only drawback of disabling the bulb check, is that system will no longer warn you, regardless if the lighting is working or not.
All you're doing is essentially going old-school and shutting off the check monitors, which is not a loss anyways, since by nature, LEDs obviously can't properly be monitored by BMW's archaic, direct current check and LEDs have a very long shelf-life; they'll probably outlast the vehicle, unlike incandescent bulb, which has a tendency to eventually burn out, essentially rending the bulb check system for LEDs, moot.

Thanks for that. I wonder why the presumed fix from dealer, at least from one member here, is a harness repair? I know someone else asked, but there must be some reason they are not just recoding. I am of course assuming, correctly I think, that BMW is aware of the issue because the issued a TSB/TIS.
