Anyone had problems with car detecting low oil pressure but not the sensor/switch.
I've got an 08 plate 500 1.3 diesel which flags up low oil pressure ... So far I've proved that there is plenty oil pressure ... The switch goes to ground when the engine is stopped (as normal) and goes open the second the engine is running ( grey/blue wire goes high - as the switch is open)
Traced it right back to the ecu plug which is 0v with engine stopped and 12v when engine is running - normal operation.
However the ecu still flags up low oil on the dash.
Does the 1.3multijet have a pressure sensor as well as pressure switch ?
Please don't answer with the usual - have you checked oil level ect ect as I've proved there is oil pressure to the cylinder head .. Sufficient to trigger the pressure switch.
