Hey All, 2007 BMW 328xi sport touring VIN: WBAVT73567FZ36514 MILES: 160k Recently bought an E91 that was sitting for a couple of years during the pandemic. From the start I knew it had its issues but still kind of wanted to learn the platform as the only other BMW I own is an E34.
All codes. Critical BMW codes: 2CFB - Charging system malfunction A0B4 - IBS communication fault E12C6 - Power management shutdown Alternator Load Test Start engine and verify baseline voltage (13.7V+) Apply electrical load: Headlights (high beam) HVAC fan (max speed) Rear defroster Voltage drop below 13.5V indicates a faulty alternator/regulator. When we see a "vehicle battery charge low" indicator on a BMW dashboard, it's basically the car's way of crying out for a little TLC.
Just like us after a long day, the battery can feel pretty drained, especially if it's had to power all those nifty gadgets and gizmos without a break. A BMW isn't just any ride; it's a complex piece of engineering excellence, and its battery is no. Why would you charge original battery and then tell car it's been replaced when refitting the same battery? Charging characteristics will be for a new battery and not an aged battery now.
Sounds to me like cas and dde need resyncing, low battery voltage can cause this to happen for some reason. Hi! I have a trouble with battery drain in e91. Drain is approximately 3a, I've started with disconecting fuse 36 in glovebox, I'd goes down to 0.09a which is acceptable.
Battery was tested and is good, new bms. Basically the start stop button is illuminated for a long time with drivers door console. Any experience what are the commons drain on them before I strip the whole car down? In.
After my CPO '07 E91 (37k miles, original battery) displayed the Low Battery warning and then stalled out once, the dealer discovered that the alternator was overcharging to the tune of over 17 volts. After the Low Battery warning happened again with the new alternator (also found to be overcharging), it was replaced again.
