: The small electric motors that drive the shutters frequently fail due to internal electrical shorts or plastic gear wear.

: While the bumper was off, they cleared out debris that could cause further "plausibility" errors—where the car's computer expects a flap to be in one position but detects it in another.

: The internal motor or gears within the radiator blind actuator are prone to mechanical seizing or electrical failure.

: Using tools like BimmerCode or E-Sys , you can navigate to the DME (Digital Motor Electronics) module and change the AKKS setting to "Wert_00" (inactive). This prevents the car from checking the shutter position, effectively "fixing" the warning light.
