VelSatis fault memory lock active

Alright, VelSatis gurus, I'm banging my head against a wall here. My 2003 Renault VelSatis (gasoline engine) is throwing a fit. It's got 249977 km on the clock and keeps showing "fault memory lock active". Basically, it's storing an error in its memory, but I can't seem to clear it. Feels like the car's computer is stuck in a loop or something. Anyone seen this before? Driving me nuts!

I think I remember something similar on mine (also a VelSatis). Does it seem to happen more when the battery's been a bit low, or after a lot of stop-start driving? It could be under voltage causing the ECU to get confused. You might also want to check your earth points. I've had strange things happen due to bad grounding. Just a thought!

Interesting... undervoltage, huh? I hadn't considered that specifically, but you're right, the battery has been a bit sluggish lately. What exactly did you experience, and did the earth points show corrosion?

Yeah, pretty much the same error message and the car acting a bit weird. I didn't check the earth points myself to be honest. Eventually, I had to bite the bullet and took it to a workshop. It turned out to be exactly what the diagnostic said: low voltage messing with the ECU's brain. Best get it checked properly!

Thanks a bunch for the insight! Seems like I'm heading down the workshop route, too. Turns out it was the undervoltage issue, as you guessed. Cost me 240€ to get sorted, but at least the "fault memory lock" message is gone!
