Thalia fault memory lock

I have a 2003 Renault Thalia/Symbol with a gasoline engine. The fault memory lock is active, and an error is stored. I think it's undervoltage. Anyone seen this?

Hey! I have a Thalia/Symbol too. I had a similar problem. The computer was acting up because of voltage fluctuations. Was anything else weird, like lights dimming or the radio cutting out?

Thanks. No other electrical issues like dimming lights or radio problems. What error codes or symptoms did you see with the undervoltage?

Okay, mine was more obvious, but I think it was the same thing – a control unit glitch from the voltage. I tried some stuff, but I took it to a shop. They did ECU diagnostics and fixed it. I'd do that before replacing parts.

Thanks for the advice. I took it to a workshop. They confirmed the undervoltage, and the computer was locking the fault memory. Repair cost was about 240€. Thanks again!
