0.5 bar would not be considered low oil pressure at idle, but another cause of a sudden change is oil pressure is a bad sending unit.

My oil pressure went to zero at idle, and I was ****ting bricks. The needle would go right back up when the car was moving, though.

It just turned out to be a bad sending unit.
