Service Due
I'm at 5K miles and get a "Service Due" message when starting. I'm assuming it's for an oil change, but there is no other details given. In my other cars there has always been a code to look up to see what specific service you're being prompted for and this seems to be intentionally vague, I'm guessing so that you bring it into the dealer. Seems pretty weak considering how far other manufacturers are with owner diagnostics built in.
I've got a diesel and I know there's an issue with the pre-mature oil change, does anybody know if there's an actual fix they're making to the computer to correct that?

From all that I have read, there is no fix. It’s inherent in the diesel design if you don’t do long commutes, you get oil dilution.
Can’t remember where I got this from:
”Diesel issue
I have spoken to LR Uk this morning about oil dilution issues regarding the different types of engine and this was the answer:- Dear Mr Bamford
I am emailing in regards to our telephone conversation today and your concerns regarding Oil Dilution.
Oil Dilution occurs over time due to normal oil degradation as well as by failed Diesel Particulate Filter (DPF) regeneration where the unburnt diesel that is used to perform a regeneration running down the piston bores into the engine sump.
This does not occur if the DPF is allowed to complete a full regeneration without interruption, but a high number of incomplete DPF regeneration's will cause a large amount of diesel to mix with the engine oil - leading to a higher than normal oil dilution, necessitating an engine oil and filter change.
DPF regeneration works by injecting additional diesel into the combustion chamber (post combustion) on the exhaust stroke so that it is used to burn off the build up of soot in the DPF. When the level of soot reduces to 'normal', the injection of diesel stops. If the DPF regen cycle is interrupted (frequent short journeys), any unburnt diesel will run into the sump, diluting the oil.
Should you experience problems relating to Oil Dilution, this can be the result of many factors and we would be unable to speculate on the root cause without the vehicle attending an approved retailer for further investigations.
As the concern can be the result of influences such as driving style (frequent short and/or low speed journeys) we would not be able to confirm the root cause prior to the vehicle attending a retailer
Once the vehicle has attended a retailer, they are able to carry out investigations and look to understand the customers driving styles as well as check for any potential vehicle faults that may be present so that we can review and support as appropriate.
I hope this provides more clarity but should you require further information, please do not hesitate to contact me
Yours sincerely”

you may try either GAP or the dealer and query whether or not there is a mode that will generate a code or a note about what triggered the service message.
The owners manual should include a blurb on what constitutes items that will trigger the message, my guess is it is some oil diagnostic, maybe DEF but I doubt it.
