Battery problems and alarm on BMW 5 Diesel
(Translated from Italian)
Summary of the thread
A 2019 BMW 5 Series owner is experiencing battery problems, with the battery appearing weak and sometimes completely discharging despite daily use. Additionally, a warning message about an "unrecognized component" appears. Possible causes include corroded or loose battery terminals, a faulty alternator, or aftermarket electronic devices causing the warning. Suggested solutions involve checking and cleaning battery terminals, testing the alternator's output, and inspecting for non-factory components that might trigger the warning.

Start by checking the battery terminals for corrosion or loose connections, as these can cause weak starts. Clean and tighten them if necessary. If the issue persists, have the battery tested to see if it needs replacement. The warning message might be related, so resolving the battery issue could help. Let me know how it goes or if you have further questions!
Probably I didn't write correctly before, I found the battery completely discharged. I jump-started it... after 30 minutes of driving the battery was fully charged to start regularly. I tried it several times, but while driving the message appeared: "unidentified component detected, please go to a workshop"

Check the alternator to ensure it's charging the battery properly. A faulty alternator can cause the battery to discharge. Use a multimeter to measure the voltage across the battery terminals with the engine running; it should read around 13.7 to 14.7 volts. If it's lower, the alternator may need attention. Let me know if you need further assistance!

Inspect the vehicle for any aftermarket electronic devices or accessories that might be causing the "unidentified component" warning. Disconnect any non-factory components one at a time to see if the warning disappears. This could help identify the source of the issue. Keep me updated on your progress or if you have more questions!
