Yet again service warning light came on in June 2020, shortly after 1st MOT. . Having had same problem fixed in October 2019, it has happened again. Couldn't get courtesy car till end September, only other option click and collect, which they now charge £30 for due to need to deep clean car in case you have Covid 19 🤣. Oil and filter changed again under warranty or as an act of kindness, apparently cars now covered for this up to 50,000 miles. JLR really need to get their act together and come up with solution, not to mention that sticker under hood said turbo failed, and when I bought ex demo car, no mention of that or the fact that it does not appear on electronic history of car. Also asked for update to sat nav, delayed to Covid 19, not convinced no updates have been available for 3 years......more investigation required 🧐

Regarding sat nav and map version assuming you are using InControl Touch:

What an awful lot of posters forget is that the algorithm in distance to service doesn't just compute probable distance based on stop/starts and regens, it also factors in original timescales.

For example, if an early oil change was made at say circa 11k and 9 months, the distance reset would not override time to next service, and the vehicle would calculate (fairly quickly) that the the service would be due in 13 months best, adjusted for journey start/stop times over a period of real time.

To give this to you in English/laymans terms - my own personal DS is not due a service until next July. It had an interim oil change at the end of July this year, and the service counter has leapt down from 19850 to 12200 inside of 3000 motorway miles. Some of you might be alarmed at that, personally I'm not. It's in keeping with TIME to next service. If it drops to 3000 miles inside the next 3 months,then all of you fretting will have a point, but I am certain that it won't. It's not just counting down oil services due to journey regens, it's also factoring in time to service as well. Something that I can guarantee that you are all overlooking in the grand scheme of things.

Drive the car and enjoy it. Stop worrying unduly, life is too short (as is vehicle life!)

Have had an interim service today and the freshly-reset service counter is reading 5000 miles to next service.. I reckon that makes sense, in light of the above, and since it's only 5 months to the 4-year service.

Pessimistic thought: When that service falls due there will probably only be 2-3000 miles on this oil (Covid travel limitations), but the dealer will want to change it and charge the full whack. Guess I'll grin and bear it!

Cheery thought: Have benefitted from FOC interim oil changes, thanks to loads of great advice from knowledgeable folks on this forum.

Just to emphasise a couple of important points in Mamil's post. It takes 10 to 15 minutes for the first post injection phase, associated with retarded ignition, to increase the DPF temperature to 580 degrees. Then, as the reproduced text clearly says, this temperature must be maintained for at least a further 20 minutes. The total regeneration process takes a minimum of 30 to 35 minutes to complete, not 20. This is from the 15 May 2015 document which forms part of the workshop manual and JLR00100.

All this time, post injection is being applied inside the cylinders. Post injection is the ONLY process that causes the dilution, nothing else. When the journey stops prematurely, as statistically it must do twice as often now, because of this faulty exhaust design, post injection STOPS. Anyone still not getting this? When the journey stops - the oil dilution stops. This might be something to recall the next time you hear or read that short journeys and stopping during regeneration causes oil dilution due to a pool of excess diesel "running down" into the sump. Utter codswallop.

For what it's worth...
I have actual recorded data proof of at least 4 regens that lasts about 20-25 minutes.

I think that's what VDS says, he is saying your total journey needs to be at least 30-35 minutes to allow time for the engine to warm up before the regen can trigger.

With 3300 posts on this topic I'm sure my question will have been covered but can you guys help me please?
I've just done my own oil/filter change on my 2018 Discovery Sport 2L SE Tech, following the change I did a "service reset" the issue is when I checked the "service due" it was at 550 miles!!!
I can't afford 7litres of gold dust every 500miles!!
Can someone tell me what's happening please?

There are two service counters to reset. One for the time/mileage, the other for the oil counter.

As far as I'm aware, you need Dealer-level Software (Pathfinder?) to reset them both. The service reset is only half the battle I'm afraid! :shock:

 

[Markylee]

Ah!!!
Ok, thanks for the prompt reply.

Not necessarily. It's a bit complicated (so maybe you do need to read the thread!) - earlier cars only have one "service due" alert, later cars have one for oil service and another one for main service. Not sure where yours lies, but if you check in the various on-screen options (using "enter" and up/down/left) you will see two readings if you have the later model.
You can reset the earlier type yourself (there are instructions somewhere on here) but the later type is dealer only.
Now the complicated bit: how much mileage have you done recently? The computer calculates the miles to service by looking at the number of miles driven, the number of failed regenerations, AND the days to the next service. If during the pandemic you have managed. say 5 miles a week, the computer works out how many miles you will do at that rate over the next 2 years, and gives you a prediction based on that.
For example, my car was recently saying about 5000 miles to oil service, but after a week's trip to Edinburgh that has gone back to a sensible figure (around 18000 from memory).
God luck!

On reflection, I think @thegavver is correct. There was an update for the earlier models, which meant that although only one figure is displayed, there are now two countdowns. The one displayed is is the lower of the two - oil service or main service. The oil service reset is dealer only I think. Assuming your car has had the update the latter will apply. Sorry if I caused confusion - I no longer have my MY17 to check.
The bit about average mileage does apply though, hence wild fluctuations are possible if you do a long trip.

You can reset both with Foxwell NT710,

Oil service reset - sets mileage to full reset distance less distance travelled since last full reset or last oil reset if there's more than one Oil reset since the last full reset.

Hope that makes sense - Full reset Distance for an ingenium diesel 2017 is 31000 KM
