30C500 er en fejl, der er gemt i din BMW's hukommelse (en ISTA-fejlkode, ikke en standard OBD-II P-kode).
Hvad det betyder: 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.
