XC90 Fault Memory Lock Active Error

I've got a 2017 Volvo XC90 with a gasoline engine, and I'm seeing an odd error. The system says 'Fault memory lock active' and that there's an error stored in the error memory. Mileage is at 204262 km. Any ideas?

I had something similar with my XC90. Sounds like undervoltage might be the culprit. Have you checked the battery?

Battery seems fine. Is it something I should worry about or can I drive with it?

If it's the same issue I experienced, it's a computer system thing. I wouldn't ignore it. I'd recommend having a workshop take a look. They ran diagnostics and cleared some fault codes.

Turns out it was indeed undervoltage. Had the car diagnosed and the fault codes cleared. Cost me 240€. Appreciate the help!
