D91DE6 är ett fel som lagrats i din BMW:s minne (en ISTA-felkod, inte en standard OBD-II P-kod).
Vad 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.
