D91DE6 er en fejl, der er gemt i din BMW's hukommelse (en ISTA-fejlkode, ikke en standard OBD-II P-kode).
Hvad det betyder: Missing 'status outer light, front electronics 1 right' message — receiver FEM/BDC, transmitter TMSL (right headlight driver). Effectively a loss of communication with the right front lighting module; common cause is a corroded connector, moisture or a failed headlight driver module.
