I have a Renault Laguna 2.2 dci and I have a fault code and the engine does not start. My question is and if any of you can confirm that disconnecting a minute the negative of the Beteria the error takes off, thanks for your comments.
Surely no. But there is nothing to try. If it does not start you, I do not think that only the failure is registered, something broken must be. Does the Gasoil steps do I have? reaches the engine? Distribution belt well? air in the diesel circuit? put a scanner and with what I put on you already know where to look.
The failure is usually removed when you change or repair the damaged component (a plug, sensor, etc ...) but to erase the memory memory I think the "clip" program of Renault should be used ... as well as the partner Igryo, if you tell us the error number, we can help you.
