The indicator needle does not drop from the highest 3.0 mark even after it has warmed in idle.
Last night in between drives I noticed that the pressure dropped to the 1.0 bar at idle, however, when I turned off the car and restarted later the bar again jumped to 3.0 and stayed there at idle (not driven).
What could be the cause of exceessive oil pressure while the car is parked?
Should I be channging a part?
Thanks much all your sharing of MB knowledge is much appreciated.
