On insufficient pressure for the low pressure switch, the oil pressure warning light should blink. Over 2000 rpm if the higher pressure swith is not satisfied the still blinks and the buzzer will sound. Once it sounds only satisfying the high pressure switch or cycling the ignition will silence it.
Dennis,
From my phone.

Steve mentioned OP light, but later on spoke of coolant level sensor. Regular flashing is not an OP light symptom, but is indicative of a missing coolant sensor wire, which he says is the situation on his van.
More info , please?

The symptoms you describe are indicative of the oil pump inlet screen blocking with carbon or sludge. With the water boxer this usually means rebuild.

However when the engine is switched off and restarted, there is no oil light. However after a few minutes, the regular blinking starts again. And once again, the speed of the blinking, on-off,on-off seems to be completely unaffected by engine rpm. My gut feeling is that its not oil pressure or lack of that is causing this but some other fault. Engine is a 2.1 from a Syncro I think and its installed in my 1989 Bluestar Vanagon. I am unsure of the mileage but was told its a little over 100k.

Are they both connected by oil passages within the engine? Is this a common fault and is it likely to be related to something in the gauge assembly and not in the engine at all?
