D357A5 er en fejl, der er gemt i din BMW's hukommelse (en ISTA-fejlkode, ikke en standard OBD-II P-kode).
Hvad det betyder: Front brake-cooling air flap: invalid signal (status) — the DSC can't read the position of the electric actuator that opens/closes the active grille/brake-cooling shutters. Causes: failed/stuck actuator motor, damaged or corroded LIN wiring, or flaps physically jammed by ice/snow/debris.
