oil pressure sensor?
 

hello fellow its been a long time...any a friend of mine just picked up a 1.8t bettle and the oil light keeps flashing...checked the oil and the level is good...i suspect the oil pressure sensor has i had them fail on my older vws but am not really up to date on the newer cars..any common issues to cause this...

Oil pressure levels must be constantly monitored to ensure that your auto's engine is properly lubricated. With the help of the oil pressure sensor attached to the gauge, you can easily monitor even the slightest changes to the pressure of your oil. Technically, these sensors function to send a signal to the gauge on the car's dashboard when the oil pressure drops to critical levels. In simple terms, these sensors are basically tasked to warn you of any drastic changes to the pressure level that is above or beyond the normal range.

It could be a faulty oil pressure sensor but there is no way of knowing without putting a pressure gauge in the circuit. Oil pressure switches don't cost much replace it but you still need a pressure test to be sure.
