I'm slowly getting a bit annoyed with this car and I've only had it a matter of weeks. More so to do with the dealer to be fair.
I finally worked out today how to check the oil level, and it's showing above the max 馃槨 I've done 800miles in it so I'm now a bit concerned about what damage may have been caused.
It's going ok next week for the fuel tank slap, dab signal cutting out when rear demister is on, wipers coming on when adjusting the steering wheel so I can add this to the list. I assume they will need to do an oil and filter change which I will be claiming back from stratstone in Newcastle. Poor show if it is down to the dealer not servicing it correctly. They provided me with an invoice for the service so I have to take it that it actually has been done, but haven't yet uploaded it to the online portal even though I mentioned it to them when I raised other issues. Had a Bmw for 18months and it only ever seen the garage for a service and mot

Sigh - amazing how some poor dealer service can so thoroughly take the shine off a nice car.

If the oil level is rising by itself, this can be a symptom of failed dpf regens.

If it was merely overfilled a touch, shouldn't be a real problem.

What you need to do is find out which of those two scenarios is the reality. The former can be serious, so an immediate oil and filter change is in order anyway.

Can you get a sample and see if it smells of diesel fuel? Indeed if you sniff away at the open oil filler cap, does it smell of raw fuel?

I took the cap off earlier and no it doesn't smell of fuel. It does smell of hot oil, which it should. But i can't actually see any of the oil because the filler is quite high up. I can't really compare it to see if it has been rising but surely there would be a warning if it was too high?
I'm tempted to just drop some out myself but I can't be bothered taking off the undertray to get at the sump plug, and I didn't spend that amount of money to have to get my hands dirty. I've got my old toys for doing that :)

As I understand it, the oil should be at the 3/4 level when it's refilled. This is how HA Fox do it. This allows for some fuel contamination through failed regents. My present XF had been maintained by non-jag specialist and showed full when i bought it. I explained i didn't want it above 3/4 in pre-delivery service.
I wonder if the 800 miles you've done have beeen short trips , giving little opportunity for complete regen.

The oil should be changed because there's a possibility that the rising oil level is due to contamination. The refill should be very carefully measured so that there's an accurate baseline for subsequent checks.

DON'T TAKE ANY CHANCES WITH CONTAMINATED OIL.

My trips have been a combination but I've had 1 journey of 160miles and 1/2 dozen or so of about 40.
I think it'd be unlikely that the fuel is contaminated when it's not even done 1k miles. If it was then the vehicle would be getting returned as being not fit for purpose. I'm fairly certain the dealer has just been lazy and overfilled it at the service

Is "fairly certain" good enough?:confused:

I think the "sniff test" is reasonably definitive - no smell of fuel in the oil = little chance of oil contamination.

Just one thing though - assuming this is the electronic oil level system - you do need to check it exactly as the handbook says - i.e. 10 minutes after switching off a hot engine, and on dead flat ground. Any gradient can throw out the reading.

One of the reasons I suggested getting the oil refilled was to test the accuracy of the electronic dipstick.

Why not get a sump suction pump and just drain a litre out, no getting under the car, all done in five minutes. Phil

Yeah I agree with everything everyone has said. I have made sure I checked the oil exactly as described. I've also tested it at other points to, to see if there has been any variation and there hasn't been.
Out of principle I don't see why I should have to go to the effort of getting a suction pump and drawing oil out of a car which was bought from a main dealer a matter of weeks ago. They apparently are the experts in these cars......
I'm not going to start throwing money at what already was an expensive car. It has a warranty on it and I have alerted the dealer of the faults so they can't claim to have no knowledge of it within the first 30 days.
As Horlicks has said, perhaps the sensor is fault and I then draw oil out which starts starving the components then that could cause premature engine failure.

It'll be put back in to the hands of the local jag dealer and they can liaise with stratstone to get it resolved, I certainly won't be forking the cost for an oil and filter change at 拢200

What if it is the level sensor playing up? Taking a litre out might not then be such a good idea.
This ^^ I have experienced a similar situation, on one time it showed up the oil level a bit high, but when tested again on the next day all was fine.

TBH, I don't check the oil level very often as it is a pain to reach the "ideal" conditions to do it .

You shouldn't be paying anything for this. Stratstone should reimburse your local dealer with the cost of an oil & filter change.

Just a small point, if the sensor is playing up and they fill it to the "correct" level relying on the faulty sensor you could be in as much trouble, how do you know if the reading is correct or not? Phil
