Default Oil pressure maxxed out.

My oil pressure gauge is reading almost 4/4 then when I blip the throttle it maxx's out. Im thinking some sort of electrical gremlin. Any experience here?

The 928 may max out the oil pressure (5 bar) at RPMs over 4000 RPM - this is the spec for the car.

I'm assuming your car is fully warmed when this happens??

The 928 gauges are extremy inaccurate. As song as they give you a reading, don't worry about what they show....as long as it'n not 0 and the ! is flashing!

If this problem just started to occur, I suspect the oil pressure sending unit to be at fault.

And yes, the oil pressure gage should read 5 when the engien is revving up.

Mike
Since there is a difference between the idle and higher rpms reading, then it is probably fine....typically when they fail they default to 5 bar all the time and don't move. Does the warning flash when it goes above 5 bar? Also what weight/type of oil?

It shows almost 5 at idle and 5 anything after a idle, warm or cold. No warning lights and im running 20-50.
