On the way home last night the Oil Pressure and Stop Light illuminated, so I stopped and checked under the bonnet. Oil level seemed fine and nothing looked wrong.
Called the good old renault assistance / AA who came out and said that yes indeed my oil pressure light was on but he couldnt find a fault.
I think it might just be the sensor / switch. Just wondered if anyone else had a similar problem before I drop it with the muppets at the Renault Garage.
Cheers
