So the frequency of short or long journeys would affect the service interval fairly significantly then?

I think that's the assumption, i.e. short journeys means failed DPF regens (so not sure if it tries again next trip or waits until the filters full again). Mine kicked off this morning into work and won't have finished - be interesting to see if it kicks in on the way home. There's no actual definition of the 'driving style' mentioned.

It isn't short journeys. Sample the oil in preparation for a full laboratory analysis including trace elements present in ppm before the evidence is lost and ask to see the diesel dilution estimate on the service reset page. My lab report is back and it isn't good news. I can't say more now but good luck with it.
Awww, how can you leave us hanging on like that! At least tell us if the oil analysis confirmed the engine's own estimate of 4.2% dilution?

The actual is 19% lower than the guestimate.

Thanks VDS, I'd say that's pretty good for a guestimate based on "driving style" compared to an actual measurement, and should give us some confidence the algorithm LR are using is a reasonable approximation of actual fuel contamination. Problem remains that the car only issues a service warning at 7% whereas anything over 2% is considered unacceptable by some industry sources :(

And that is the real issue. My oil is no longer 0W-30 and metal parameters are high or above recommended levels. The engine is basically not being lubed properly. It has done 5K miles.....

That's very worrying that the oil isn't doing its job, especially as yours is not even at the point where LR feel it requires an oil change, whether measured on the normal service interval or the fuel dilution calculation.

By the way, what did the soot levels come out as, as I have a suspicion that the EGR results in high soot levels as well?

I think that's the assumption, i.e. short journeys means failed DPF regens (so not sure if it tries again next trip or waits until the filters full again). Mine kicked off this morning into work and won't have finished - be interesting to see if it kicks in on the way home. There's no actual definition of the 'driving style' mentioned.
How can you tell when a re-gen is happening? My D4 used to growl like a V8 when it did a re-gen but so far I've not noticed any change in exhaust tone or engine performance. I do a lot of motorway, A road and hooing on B roads. Very few short journeys.

Bit worrying that my service indicator was reset at 11K miles (based on LR advice) as am I now driving around with potentially contaminated oil?

Stop / Start is disabled (it won't stop - unfortunately the dash light is still on), your fuel economy drops through the floor as it injects extra fuel and when you get out the car there can be a 'hot' smell and exhaust tinkling as it cools.

I don't understand why you'd have the early service light with your 'driving profile'. It seems to kick in around 5 minutes into a trip and last about 20-30 minutes, if you're doing very few short journeys you'd think you'd be the last one to have early oil change.

Thanks -9

Mine reported an oil service due in 3K miles in the Service menu (I was checking the AdBlue range pre-vacation) not as a warning light... maybe thats why LR said to just reset it ?

Maybe my re-gens happen at speed and I've not noticed then ?

Cheers

Most likely, the increased fuel consumption would get hidden in the longer trips average.
