Oil pressure light in an older Passat?

I keep getting a "Stop Engine - Low Oil Pressure" message in my 2002 Volkswaegn Passat GLX V6. The oil levels are correct, is it faulty? Can I reset it somehow?

Might be a blocked sump oil strainer. Might be a failing oil pump. Might be a faulty pressure switch. But most likely to be one of the first two and if you don't fix it your engine will scrap itself.

I own a 2004 Volkswagen Passat and it won’t start. A light has come on, saying “oil pressure low - Stop”. The engine is also making a chattering noise. Do you have any idea what could be wrong?
The low oil pressure warning light comes on in my 2013 Mazda 2.2d. What does this mean?
One week after my car was serviced the engine has seized. It's still full of oil, but now refuses to work. Could it be something the garage has or hasn't done?

A better drive and better equipped than the previous Passat. Comfortable and has more status than, say, a Ford Mondeo.
