30C500 خطایی است که در حافظهی BMW شما ذخیره شده است (کد خطای ISTA، نه کد استاندارد P از نوع OBD-II).
یعنی چه: Active grille shutters / radiator blind stuck or restricted (intermittent, plausibility: blocking). The shutters don't open/close properly, affecting engine-temperature regulation and aerodynamics. Causes: debris/leaves/ice in the mechanism, failed shutter actuator motor, bent louvres after a front-end knock, wiring/connector issues.
