I have recently noticed a very strange oil pressure trait on my car (essentially 12V 300E). When cold started oil pressure only goes up to about 2.7 bar, no further even when revved. As the car warms it rises to 3. After this it is as normal, 1.5 bar at idle, 3 bar when revved. I'm thinking that this could be linked with the most likely electrical gremlin which is also causing my idling issues. Car seems fine otherwise. This happened after a 140mph run it received a few weeks back.
