804081 er en fejl, der er gemt i din BMW's hukommelse (en ISTA-fejlkode, ikke en standard OBD-II P-kode).
Hvad det betyder: Drive readiness: implausible bus signal — «production/diagnostic mode, faulty». Most often appears with a weak/discharged battery, after long parking or after diagnostics; frequently self-clears. What to check: battery charge and terminals (>12.4 V with engine off); if it returns after charging — network/module diagnosis needed.
