XC60 Battery Drain Electrical Issues

I own a 2018 Volvo XC60 with a diesel engine. Recently, I've been experiencing some difficulties with the car's electrical system. Specifically, the battery seems heavily discharged, causing an error message in the speedometer, weak and flickering lights, and a stored error code I read with an OBD2 scanner. The battery also seems weak when starting. Could this be a faulty battery and how can I verify?

A 2018 Volvo XC60 owner experienced electrical issues, including a heavily discharged battery, error messages, weak lights, and starting difficulties. The problem was suspected to be related to the battery or charging system. It was suggested to check the battery voltage with a multimeter to determine if the alternator was charging correctly. Ultimately, a defective battery sensor was identified and replaced at a workshop, resolving the issue.

Did this summary help you solve your problem?

Those symptoms definitely point to a battery or charging issue. Have you tried checking the battery voltage with a multimeter when the engine is off and when it's running? That might give you a clue if the alternator is charging correctly.

Thank you for your quick reply. I have not yet checked the voltage with a multimeter. Could you elaborate on what readings would indicate a problem with the battery or the charging system?

Sure thing! With the engine off, a healthy battery should read around 12.6 volts. When the engine is running, you should see somewhere between 13.7 and 14.7 volts. If it's significantly lower when running, your alternator might not be charging the battery properly. But given the error codes, I would go to a workshop and ask to test the battery sensor. This is definitely a task for experienced technicians!

Thanks a lot for your advice! I took your suggestion and brought the car to a local workshop. They confirmed that the battery sensor was defective, and after replacing it (costing around 315€), the problem seems to be resolved. Your insights were very helpful in guiding me toward the correct diagnosis.
