VW Polo 6N2 dashboard oil light flashing & beeping?!

[mhmg511]

Hi,

I have a VW Polo 6N2 & am having a problem with the oil waring light on the dashboard flashing & beeping whenever I start the car & reach around 2000RPM (don't know if the RPM thing matters). It doesn't seem to matter wether the car is started from cold or warm, it happens ever time.

I'm thinking it could possibly be the oil pressure warning switch or the oil sensor but am not sure. Any advise would be greatly appreciated as I don't know what to do.

Thanks
