Firstly, start by checking the battery connections. Make sure they are clean and tight. Next, use a voltmeter to check the battery voltage. If it's below 12.4V, it might need to be replaced. Also, check the alternator belt for wear and tension.

Another common issue with BWM electrical systems is faulty sensors. Use a diagnostic tool to check for any error codes related to sensors. If there are any, replace the faulty sensor.
