apparently for porsche the oil % on the oil level computers that porsche uses is 200% is when its totally full. I got a low oil level warning message on my display and the technician says its still showing 155% oil level and that i shouldnt look at my oil level sensor because its faulty.....does this make sense?

does low level warning on the display correlate to 155% oil level on the porsche computer?

 

does anyone know what the reading for the oil % level on the porsche computer should read out when our oil level displays is showing as 0 bars/Minimum oil level?

 

Never heard of Panamera being 155% filled and showing low oil level.
There is no dipstick on Panamera v8.
You should monitor and top up oil every time you fill the car with gas.
Develop a habit and stick with it.


Checking oil level on Panamera (and similar gen Porsche cars):


You can see how much to add, and how much is in the car after driving at least 6 miles (if hood was opened for any reason). See pic below to tell where oil is.
Each segment is equivalent to ~250cc, or 1/4 of a quart, or 1 regular size glass 8oz.
Owner's Manual for reading: Page 108:

 

Makes no sense at all...

 

so when we are at a minimum lvel on our display what should the porsche computer be showing the % as? i know from multiple people they say when its full its at 200% on the porsche computer

 

when you say computer, do you mean PIWIS2? The car itself has a computer, commonly called the ECU, and keeps track of levels.
The car itself shows you pictures like I attached above.
If the level shown after driving at least 6 miles is at the minimum (yellow, or pricture C from above), you would have to add at least 1 quart.
Each of the 4 divisions is about one glass or 250cc or 1/4 quart.
Once you add what you need to get to the top of upper most square, you close the hood, drive for at least 6 miles, then check in the car (even if car is moving).
Then, you will know how much more to add. If you overfill, it will let you know. Then you would have to open drain plug a bit to remove excess.

 

right i understand that, and yes i bbelieve its the porsche diagnostic tool. The previous tech told me that my display is not showing the proper readings so he said to ignore the display on the car and all those bars. He said then when the vehicle display was showing the "min" level of oil i still had 155% so i was told i need to replace the sensors

 

Porsche designed this display, so that owners can have proper level of oil in the pan, without having to go to the dealer to check it for them.
Otherwise they would have stated that to check oil one must go to dealer, and connect to PIWIS2, for a check. This automatically means nearly $100 to do at leader.
Maybe mechanic has some base to say so, but I would disagree with him saying disregard the display. It is designed specifically for owner to have proper level.
I think you should follow what owner manual says. Your car and $ though.

 

thanks appreciate the reply, just getting frustrating having to top up the oil every 2000km not sure why it burns through oil so fast

 

Panameras, Cayennes, I own, all burn in.
You will hear from nearly all Porsche cars they have to add oil to keep topped up.
I own turbo versions, and it consumes oil thus need to add.
There are various places where oil can leak out too, aside of the engine valve cover gaskets, which would increase oil consumption.

As a Porsche owner, you would have to accept that as reality and check oil every time you fill up. I check every couple days on display.
Toyota Sienna I own too, never needs top up, what I put in it, is what I remove at oil changes. But again, thats a Toyota vs Porsche - which would you prefer to drive?
I know which I do.

Dont sweat the level unless you go through quarts a week or two, there are many threads on Porsche forums on oil consumption. Enjoy your new car.

 

the whole higher than 100% thing is bizarre - however if the sensor is bad - it will be displaying the wrong thing..... But wouldn't it also be telling the mechanic the the wrong answer as well?

with no dipstick there is no analog way to measure the oil level with it in the car. the only way I can think of that you would know for sure is to drain it and measure it.

good luck

 

Good mechanic would tell if display sensor is not working right. They would know that it needs replacing. Thats why hard to find good mechanics, they are human just like us, and do often make mistakes.
One huge reason I prefer to do everything on my own - feeling and knowing its done 100% like I want it, without excuses if something does get screwed up. Gives me better appreciation for the vehicles I drive, and better understanding (no comparison here).
A good way to tell, get a clean oil collection can. Raise car, drop all oil into it. Measure how much came out. Compare to required fill without oil filter change (depending on your engine). Pour the oil back in. Check oil level and see if indicator says you are low or not.
If shows you are low, sensor may be off. If shows level OK, I would question the mechanic.
Lots of extra work, but can be verified.

 

..I would compare the 'why does my Porsche use up oil' question, to 'Why does it rain in Seattle all the time'. Answer for both is 'because'.
So do what manual says, verify (on your own) if makes you feel better, then adjust if needed and continue on.

 

Don t quote me but I believe if the system wasn't t working the car would tell you that.... other systems all do that.
For the record my non turbo V6 uses NO oil at all between 10K oil changes.

 

We have updated your record.


No, seriously, I never owned non turbo Porsche, so I can only attest to them. Turbo versions do use oil. Manual tells you how often you should expect to top up, and how much.
Non turbo versions apparently may not need this additional service step.
Thanks for updates. They give useful info to those lesser Porsche experience.
