So after totalling my beloved and reliable 2001 330Ci, I've bought a 2009 525i. The onboard computer shows nothing amiss beyond being overdue for a service (which has actually been done but my mechanic couldn't reset it). Today, the check engine light came on. I assumed it was complaining about what it saw as an overdue service. But out of curiosity I ran the OBDC I have over it, and got more codes than Alan Turing at Bletchley Park. These include (some codes may be wrong as my photos of the screen have reflections): 93FB - control-module fault 9408 - undervoltage during self test A3B1 - signal or value below threshold A559 - Supply was switched off (terminal 30G - f) A2CD - control unit undervoltage A46D MOST - ring reset fault 5B69 - wheel speed sensor rear axle: mixed up (!!) SF4B - Interface, instrument cluster 5DCF - Control module, under-voltage 5F45 - brake fluid level too low (this was topped up during the service just before Christmas) 6140 - redundancy comparison, driver's steering angle A830 - resetting system faulty A83B - Undervoltage 93D0 - Undervoltage A409 - Undervoltage 931D - System voltage When the car was trucked from Auckland to Wellington it took so long the battery went flat. I therefore invested in a new one from the AA at over $750 (on top of several thousand $ getting my dad's old car going as a back-up for the family and for sentimental reasons, plus of course the purchase price, all right before Christmas) 😬 So the multiple undervoltage faults can't be traced back to the battery. So my questions to the brains on this forum are: What's the possible cause(s) of the undervoltage reading? Could undervoltage be causing all, or at least some, of the other faults to show up? Why is the onboard computer showing everything okay other than oil and brake fluid? Obviously I'll double check the brake fluid visually, but aside from that is there anything here that's absolutely dire and could affect the safe operation of the vehicle or damage it if not addressed immediately?
1998 E46 328i Sedan, Auto Trans is in emergency mode with the little Cog next t the gear indicator. Seems to operate ok and doesnt shift nastily or anything. I've hooked up my carsoft 910 and it reads 97 CAN status, fault Have searched everywhere but cant find much about that. Coincidentally the airbag light has come back on and I cant query the SRS for the fault code (communication error). It has been fine previoulsy when I installed an airbag bypass sensor for the passengers seat a while ago and reset the SRS. Could they are related? Wondering if the SRS module wont query has this thrown the EGS into Emergency Mode?
