Having been used to a 2.7 setup I decided to check the oil on my recently acquired MY2012 3.0 S. After searching and deciding there wasn't a dipstick I resorted to the handbook. The car had been driven about 20 miles so was at the designated working temperature and been parked on level ground for about 30 minutes. The result of the prescribed stalk prodding revealed result 'D' in the manual, overfilled, do not drive the car !!!!

So I did drive the car to the dealer to report said result. They then had to wait 10+ minutes for the reading to show which was then at the correct level. I/they can only assume that leaving the car for 30 minutes (as I did) slightly more oil found it's way into the sump and the difference is negligible.

I would prefer a dipstick as has probably been the measure of accuracy for getting on for 100 years. How do we or the dealer know this gizmo works right ?? The dealer had no means of checking the oil level other than the system on the car.

I don't like it :(

Just not sure about that, I check mine after an overnight stop, and see the correct level. It IS very sensitive to gradients though.

It does say in the handbook "ensure the engine oil has reached working temperature (is hot) and the engine switched off for 10 minutes".

If I do it after just 10 minutes as said it displays "LEVEL OK"

When I left it for half an hour it said "SEE HANDBOOK" which is illustration 'D' in the book and Oil level above maximum for safe operation. Do not drive the vehicle. Seek qualified assistance.

It was on perfectly level ground both times.

It (the instrument to check) might be very sensitive, so no real reason to worry especially since you also checked with your dealer :)... just adding that with a diesel and the PDF there are instances where diesel might mix with the engine oil an thus increase the oil level ... and dilute the oil, decrease lubrication and .... :argh:

But since yours is rather new, regularly driven over longer distances and has no problem with DPF this should not be the case I assume ;)

When was the dipstick actually discontinued? I don't appear to have one. There is a tube I assume it should go in, but it has a cap on it. I haven't found how to get the level on the readout, so I hope it tells me when it gets low.

Checking the oil level
For an accurate oil level reading to be taken, the following conditions must be met:
• The vehicle needs to be parked on level
ground.
• The oil level should be checked when the oil is hot. It is therefore recommended that a reading is taken after a journey.
• The vehicle needs to stand for approximately 10 minutes after the engine is switched off, to allow the oil to drain back into the sump.
Note: The system will not give a reading until the oil level has stabilised.
Once the above conditions are met, check the oil level as follows:
1. Switch on the ignition - do not start the engine.
2. Set the transmission to Park (P).
3. Press the TRIP button on the end of the left-hand column stalk repeatedly, until the oil can icon is displayed at the bottom of the message centre.
4. The oil level and topping-up advice will be shown in the message centre. Top-up as instructed.

none of the 3.0ltr diesels have a manual dipstick, there all electronic.

Hi I bought my Jaguar XF 3.0 supercharged 2016 one day before Jaguar shutdown for Covid 19.
I checked the oil level it was showing 1/2 when I checked it the next day it was full, the next day 3/4 and it’s been fluctuating every day since I’ve had it. The car was purchased from Inchcape Jaguar Norwich with 12 months warranty, I booked it in for the oil sensor to be looked at, on the first visit I was told that the sensor had been changed. The next day the same problem. Went back again two weeks later and they told me it is working fine and it was checked with no problems. Next day oil reading was incorrect. The car was booked in again, this time I had a courtesy car so they had my car for four days.  I have been told again there are no problems and it is working fine. I have given Inchcape numerous pictures of the oil reading with dates and times showing all the faults over several weeks.
I believe that if all Jaguar owners were to check the oil level once a day for a week they would find the same problem and that would force a recall, Jaguar will not tell you about this problem.
If anyone has had the same problem and knows the cause of the problem and have rectified the problem please let me know.
Thanks Glenn

It's how mine behaves. It's not a problem. Stop looking at it.
Now, if you get a low oil pressure warning . . .

Hi first of all thanks to all who replied to my post.
Inchcape Jaguar Norwich contacted  me to collect my Jaguar and told me all was working as it should be and the reading on the gauge is staying in the same place every time. I told them if I check the car and it was still reading wrong I would be keeping the courtesy car till it was sorted. As we went to the car the customers service 
assistant told me the levels have been checked all day and has been on 3/4 full every time, which was strange as they have constantly told me they always fill to top! When I took the reading it was only half full, I was told to keep the courtesy car and now the Jag is being looked at once again. Hopefully now they know there is a problem perhaps they will deal with it.
My mechanic predicted it could be wiring loom or ECU unit, hopefully we will find out soon, I will post the results.
The thing to remember is if you buy or lease a car it is your responsibility to check the fluid levels and this is impossible if the gauge is reading incorrectly.
Thanks Glenn

Were I on my way to catch a cruise ship or indeed a flight, as I often did before a certain pandemic stopped all that, it would never occur to me to check the oil level in my car. And never has.
