Look Up BMW Series Chassis Codes
Have you ever wondered what BMW chassis codes are? In the following tables, we have provided a BMW model codes list.
In this guide, we go over common BMW charging system problems that trigger the battery light to stay on.
It is important to understand that if your BMW displays a red battery light or a charging system error on Drive, the vehicle may shut off unexpectedly when driving.
When you get a battery malfunction on a BMW, pull over and soon as it is safe to do so and switch off all non-essential electrical equipment and unplug any chargers plug in the cigarette outlet and USB ports. Turn off heated seats. Rear window defroster and set the blower fan to a minimum if required.
Keep in mind that the vehicle may not restart and may need to be towed to an auto mechanic or repair shop.
All newer BMWs use various monitoring systems to ensure balanced and efficient charging processes. In case of a problem, the monitoring system will alert the driver with a charging malfunction warning message on the iDrive display.
Additionally, there will be a red battery icon illuminated on the dashboard.
Possible error messages and symptoms include:
Most BMW charging system problems are caused by a faulty alternator or weak battery.
To troubleshoot your BMW battery problems, start by checking the charging system to determine if the battery and alternator function properly.
The next step would be to use a BMW All System scanner to read the fault codes via the diagnostic port located under the dashboard on the driver's side.
Common problems that trigger BMW battery warning light include:
You might be confused as to whether the problem is with the battery or alternator.
To determine what is causing the problem visit an auto parts store to perform a charging system test or use a Charging System Analyser to check the battery and charging system yourself.
If a charging system analyzer is not available, use a voltmeter to check the battery and alternator.
This simple test procedure will give a good insight into the battery's condition and the electrical system.
Don't ignore the BMW warning light. Do not continue to drive with the battery light on as there is a high risk the vehicle may shut off unexpectedly while dring.
If the BMW battery warning light on the dashboard comes on while driving and iDrive displays a warning message, the charging system is not working properly. The problem most likely is a bad alternator or battery, but the fault may be something other than these two components.
