Morning, so this has popped up again, done just over 1k miles on fresh oil. Surely it doesn't need another oil change after that many miles. The only thing is I performed no service reset after I changed the oil. Any ideas thanks.

I notice you didn’t do a service reset after the oil change . As you didn’t reset it, I think it could be the same message sequence counting down the miles. How many miles to service did it say in November, and how many is it saying now? It can take some time between this countdown and you’ve only done 1000 miles. ( message normally reads , service required in xxxx miles).
My understanding is that, without a reset, you haven’t done anything to reset the oil dilution calculation the car has.
Let us know. If you had an IID to can view the oil dilution percentage the car has calculated.

Hi
The service required message normally starts with a miles countdown message.From my own personal experience (rather than expert knowledge) it seems that each time it reaches a new threshold, it flashes up the message with a new, lower, mileage. Normally starts at about 1600 pr 1800 miles iirc. This service required message doesn't come up every time you start it on mine, like yours, and there is no indication of the message when using the menu options on the dash (ie service menu). Frustratingly , the message flashes up very briefly ( perhaps 3 - 4 seconds) and then is gone, and as I say, the next time you start the car there is no sign of it (until you hit another, lower, threshold). So, I don't think there is anything unusual in the behaviour regarding the delivery of the message on your car. The strange thing is, that you didn't get a countdown. I wonder if you missed it? I also cannot remember if when there are no miles left to when a service is required, it will show up every time (anyone out there know?). Without being patronising, it is very easy to miss the mileage (personal experience).
I maintain that the car would not have known you changed the oil. Given my understanding of how oil dilution percentage is calculated which uses the number of incomplete/partial DPF regenerations to estimate how much of the extra diesel it uses has not been burnt off. It does not actually analyse the oil itself, if the reason for the message in November was oil dilution (quite possible on these) then that calculation /estimation would not have been reset and would still be being used by the car to provide service messages.
Worth looking to see if you have any error messages using a tool. In addition, if you do get hold/borrow one, also check the miles to next service and oil dilution percentage paramaters too. Those parameters may help you find out what's going on. Approaching/over 6% is when service required in messages start.
A couple of other thoughts/questions that might assist. Did you get all the oil out? They take 5.9L and may be a bit more if oil is diluted? Do you do a lot of short journeys?
Good luck. keep us updated
