Hi, While my 2.3 / 150 Ducato Motorhome was in the garage yesterday I asked them to check the Oil Pressure at the pressure switch because I've had the "Oil Pressure Low Stop and Turn of the Engine" message from new basically. My Local Fiat Professional Garage (supposedly) could not diagnose the fault but my independent garage told me that there is a 3 second delay from starting until the pressure reaches the switch. They fitted a temporary gauge to see the pressure. Has anyone else had this problem and how was it rectified.
