No idea if this is the right place, but here I am.
Advice needed please.
Just moved the van and when I started it--- in big letters it said OIL PRESSURE TURN OFF ENGINE, but within seconds the sign had gone. I have checked the oil, lovely and clean and up to the mark so could this be a false alarm?
A couple of years ago we were driving along the Mosel(Moselle) and the oil pressure light came on. Like you I checked the oil level - OK. My assessment was a faulty pressure transmitter rather than the pump.
However, I know that running an engine without oil lubrication can be disastrous, so took the cautious approach and called ADAC. The guy arrived and came to same diagnosis, so he said he would follow me to a garage.
Sensor was changed and all OK.
I would suspect that the sensor/transmitter is starting to play up, so needs checking. The solution may just be to take it out and blow it through with a high-pressure air line to check for any detritus in there. Or a new sensor.
Anyway if the light has gone out it is probably safe to drive to a garage. But if the light comes again on the journey then STOP and turn off engine and call Recovery.
We had a fluctuating oil pressure guage on a Bristol Freighter climbing out of Jersey. As it happened the Captain had done an engineering apprenticeship at DeHavilland. He immediately shut down the engine for the same reason(did not wait to check with me that it was correct engine - naughty). It was the transmitter.
Hope this helps, but wait for more informed replies before taking any action.
