Battery come loose ,lost my radio .now my tempeture icon keeps going up and down ,then I get overheating icon come up on screen even when engine is cold .radio stalk not activating nothing neither is my hand held remote not doing anything .ive checked the live feed to my radio all fine cd changer looks fine .
If the battery is ok and the connections have been sorted out now it may be that the breaks in continuity have corrupted the ecu software. I'd take it to your Renault main dealer and get them to check it out and reload the software if necessary.
