Mine has had the same, loose cable under the drivers seat, give them a wiggle and push them into their connectors. I'd do it after the ignition has been off for a while... just in case
ah in that case I'm not sure then, mine just had the light come on, didn't bother plugging the reader in.
Ah ok... cheers thanks for help anyway. What usually goes wrong with the seat connectors? I've heard of re-soldering and stuff before?
The wires rub I think and over time wear down when the seats are moved back and forth because renault most likely make them from tissue paper or something of the likes in order to save some £££.
Just wiggle them about and it should sort it
