2000 Wreg 1.4MPI Buzzer/oil light flashing - langdon
Nothing wrong with engine whatsoever, smooth, fresh oil, doesn't overheat, leak etc, no rattles, except as soon as you start up and pull away with any kind of Revs the buzzer sounds and light flashes with a red oil can! continues to flash until you turn off the engine, no matter how long the journey! Help!

A flashing oil light may mean a circuit fault. There is a rev component to the system [2000 revs?] that requires the second [high-pressure] switch to be closed before it's exceeded.

Get the pressure verified before you do anything else; but this could be a duff pressure switch, a broken wire to one of them, or a lack of rev info to the dash.

Are we saying there are more than one pressure switches? I have found the one at the bottom front of engine(standard 24m screw in thread) and broke the pac switch next to it at the same time!!! even with the oil switch out and unplugged it still beeps and flashes!!!!!

That's because the flashing light is to indicate a fault with the oil pressure warning circuit itself - a switch open-circuit at the wrong revs etc.

I don't keep Skoda wiring diagrams; so as to the exact layout, number of switches etc. you'll have to consult a Haynes manual.
