^^^^ If you’re that paranoid, then don’t mod anything on the car. I think you’re blowing your worrying a bit out water. Codes for missing light or light bulbs going out automatically retest and get cleared off the active DTCs on the respective modules. They don’t deal with engine or environmental issues, so they don’t even keep a historical record in the module. About the wildest thing I can think of is if you leave the car connected to the BMW link and whenever something gets set off (mostly drivetrain/safety related) the car will upload the DTC problems and try notify the service dept at your dealership.
