I was off down the motorway today when the oil pressure light came on all of a sudden... So i pulled over, and as i was waiting for the AA to come i tried starting the engine again, and the oil pressure light came on at tickover but when i revved it the light went out... The longer i left the engine the quicker the light went out...
Any ideas? Its full of oil and was running at normal temp.
The motor is a 200tdi defender
