XC40 Fault Memory Lock Active Error

Hi, my 2022 Volvo XC40 hybrid is throwing a 'Fault memory lock active' error. The only symptom is the error stored in the error memory. I'm suspecting undervoltage. Anyone seen this before?

Ugh, fault codes are the worst! I had something similar with my old Peugeot – the computer system went haywire and locked up completely. Did you check the battery?

Yeah, battery seems fine. How did you resolve the issue with your Peugeot?

Honestly? I ended up taking it to a workshop. Turns out the control unit had a meltdown. It was a pain, but they sorted it out. I'd recommend getting it checked before it gets worse!

Thanks! Shop diagnosed it as undervoltage causing the memory lock. Repair cost was 240€. Appreciate the advice!
