Question about 1992 Volkswagen Cabriolet
Driving for miles all is ok , park for a bit start again, valves tap and then buzzer comes on
This vehicle as well most other Volkswagens of that era are notorious for oil sludge in the engine. Go to any Vw forum and you will see. You have to get this sludge out or otherwise it contaminates fresh oil and makes it lose its viscosity.
As far as the oil pressure, DO NOT DRIVE WITH NO OIL PRESSURE. If it is making noise from the valve train, there is no pressure. Be very careful running it, you may ruin an internal engine part. If you can idle it until the noise lightens up, then you can drive as long as there is oil pressure.

There are two pressure switches. One for oil pressure and one for a dirty oil filter. Are you sure you've changed the right switch. If car drives for 30 mls it doesn't sound like you need an engine. The spluttering is likely to be completely unrelated to the oil warning I suspect.

Hi. there are many issues that can cause this type of situation. the oil pressure sending unit may be malfunctioning. there could be a faulty module or the wires and connectors could also be lose or faulty as well. you could also have a clogged oil filter but, that usually isn't the main issue here. the most common problem here would be a bad oil screen in the pan or a faulty oil pump. you will find the problem in these areas above.
Please rate and god bless:)

a plunged oil filter will do this so will a bad oil reg.
try changing your oil and get a new filter
also you may have had the incorrect filter on it "some shops do this"

The oil pressure relief valve should be on the oil pump.If your oil pressure is ok,have the wiring tested to theswitches or try another set of clocks

The oil pump is relatively easy to change with the engine in situ if it is (commonly) at fault,
Get an oil pressure gauge with a pipe and brass fitting ready on, (borrow or buy cheap from boy racer shop), unscrew the sensor (or ask the garage to for a £5) and plug it directly into the sensor hole after you've been for a run.. When warm, mine sits about 40 at motorway speeds, ten at tickover.
