CA941B er en fejl, der er gemt i din BMW's hukommelse (en ISTA-fejlkode, ikke en standard OBD-II P-kode).
Hvad det betyder: Message timeout in the vehicle-information network (BMW infrastructure): a module didn't receive expected vehicle-info data in time — usually the head unit (HU-H), surround-view camera or driver-assist. Symptoms: iDrive glitches, 360° cameras not loading, assist features briefly unavailable. Most often a software hiccup or a voltage drop (weak battery).
