I've changed the oil not too long ago and for some reason the oil light shows up while driving along. It doesn't always happen but it shouldn't happen at all. The level's fine and it's not leaking. Only thing I can think is a faulty switch. Are these easily replaceble or can it be repaired?
If there is no increase in engine noise when this happens, then it may just be the oil-pressure sensor. Oil pressre alarms come on at a few PSI of oil-pressure, and if it was really the case that the engine was experiencing low OP, you would see that light more often when the car was hot (up to temperature) and at idle, while at traffic lights for example.
Does the oil-pressure light illuminate, when the ignition-key is at the 'ON' position before actually starting the engine? If not,.its possible the sensor is knackered or its wire is off, earthing itself intermittantly, thus giving you that false light.
