Peugeot 5008 Error Memory Lock

I'm pulling my hair out here! I've got a 2021 Peugeot 5008 diesel, lovely car, but it's throwing a fit. Mileage is at 88252 km. The error memory lock is active, and all I'm getting is a generic 'Error stored in the error memory' message. No actual details! Anyone else run into this wall of frustration? Thinking it might be a control unit thing, but I'm not sure how to proceed.

A 2021 Peugeot 5008 diesel was experiencing an error memory lock, displaying a generic error message without details. The issue was suspected to be related to the control unit. A suggestion was made to check for undervoltage, as it can trigger the ECU to lock the error memory. Upon professional inspection, the problem was confirmed to be due to undervoltage caused by a faulty ground connection, which was subsequently repaired.

I had a similar issue with my 5008. The error memory lock suggests a deeper problem that the ECU has flagged. Have you checked the vehicle's voltage recently? Undervoltage can trigger this kind of lock to protect the system from damage.

Undervoltage, huh? Interesting. I hadn't considered that specifically. How would low voltage cause a memory lock? And what exactly did you do to troubleshoot it when it happened to you?

The ECU monitors voltage levels, and if it detects consistent undervoltage, it can lock the error memory to prevent further corrupted data from being stored. In my case, after checking the battery and alternator, I found no problem, so I brought the car to the shop where they fixed it. I suggest you have it checked by a professional, it could indeed be expensive.

Thanks a ton for the insight! Really appreciate the tip about the undervoltage. I took it to a workshop, and it turns out you were spot on! The garage confirmed undervoltage. They reset the system and found a faulty ground connection. Repair cost me 240€, but at least the gremlin is gone!
