Two thoughts:

Does the Panamera have an oil pressure relief valve? Ages ago I had a 1953 Sunbeam Talbot that had a spring loaded relief valve in the main oil feed. Sometimes it would "stick" open, drastically reducing the oil pressure.

Is the Panamera oil pan baffled? If not and the oil level is a bit low, acceleration or turning could result in momentary starvation at the pump intake.

That did not make a difference, after a few days the error reappeared.
Next on my list is the solenoid in the oil pump, it seem like an easy job too, if that does not work I will replace the oil pump, expensive but I have not read of a single case where that did not resolve the problem.

Hello, i had same problem, first i changed only sensor, then solenoid and problem gone. Dont worry about oil pump its very strong inside.

JohanvdWalt

it does not say no oil pressure, that would be in red.
In fact it say oil pressure monitirong problem in orange.
I checked it with obdII scanner and found the pressure arround 7Bar which I asume is too high causing the warning.

Unnamed335

Yes its too much, strange, maybe some firmware error?

i have the same problem ! Obdi scaner shows oil reading above 7 bar . I changed sensor and solenoid pump and still the same ! Than I flushed the oil with oil flusher and it was ok . As soon as I pressed sport chrono it started to do it again !
it must be something inside the oil pump

Can you tell, when error coming, its on highway aftee long drive right? Or in city (sport+ driving)? So when error coming about pressure sensor, it means pressure too big or just solenoid dont work correct.

High Oil pressure mean:
1. Main Oil pump (maybe cranchshaft sensor)
​​​​?

no , as soon as you star pushing it , over 5000 rpms , preasure builds ups and it lowers slowly . Its very easyr if you push it to be above 5 bar . On sportchrono is just a metter of 1-2 minutes . Because it keep gears high . It may be something inside the pump which gets stuck

albania92

yeah the scanner diagnosed , sensor , dirt oul filter , solenoid pump , clodged oil passages (i did the flush ) and finally the pump . When I did the flush it was ok for sole days , as soon as i pressed sport chrono its doing it again

I just collected the solenoid from my local dealership, this is what it look like:





ealer, this is what it look like.

JohanvdWalt

I've read that some oil will leak out when you remove the old solenoid.
Can someone please tell me, is it just a but of oil or should I rather drain the engine oil before replacing the solenoid?
Also is there any other seals I should replace when in there or is it just the two (Black and Green) that come with the new solenoid?

JohanvdWalt

I found this nice write-up that explain the process and yes it is necessary to drain the oil first.

Ok, im depressed.

I got the "no oil preasure" and just drove it the closest place and parked it. Vent to a car repair shop and got the front sensor and oil changed. Still the same error.... The car has absolutly no oil preasure or temprature. Should the next step be to change the solidute ? IT's a cost of 400 USD here, any suggest if it can be bought other places, can it be any other sensor ?

JohanvdWalt

This sound like another problem, we have the oil monitoring warning in yellow, not no oil pressure which I presume would be red?
If I remember correctly the same sensor measure oil temp and pressure so hopefully you fitted a dead sensor or you might have a wiring problem?
