Peugeot 206 Fault Memory Lock

Hey, I've got a perplexing issue with my 2000 Peugeot 206 diesel. It's clocked 160068 km. The fault memory lock is active, and it's just storing an error. I've checked the battery connections, but no luck. Any ideas?

Sounds like undervoltage. Any recent battery or electrical issues?

Thanks! No recent battery issues, but it's been sitting idle longer than usual. Could that cause a fault memory lock?

Yes, inactivity can cause undervoltage, triggering the fault memory lock. A workshop visit is advisable for proper ECU diagnostics.

Thanks for the guidance! Took it to a workshop, and they confirmed undervoltage. They reset the fault memory and charged the battery. Cost me 240€. Thanks again!
