I always leave mine plugged in, no battery issues. 2018 SE SDV8 4.4 Byron Blue

Sigh. So after three and a half months and just under 4500 miles car is saying it needs a service soon. Nine days ago it said I had 2,876 before the next service and during that time I've done - wait for it - 567 miles.

I really like this car, it's been utterly brilliant on our current trip to Umbria but this service interval malarkey is just annoying. It doesn't seem to matter what I do, short or long trips, the intervals just don't stack up.

Anyway, oil change when I get back. Does anyone know how to reset the service indicator when the oil is changed? I suspect I'll just end up taking it to a dealer anyway but would be useful to know if it can be done. 2017 Vogue SE

Just out of interest are you tailpipes sooted up, should be spotless inside if the dpf is operating correctly?

I have a similar problem, doesn't matter what journey distance or time wise I do (bearing in mind I do 1k plus per week) service intervals are ridiculously short. Never get any dpf warning, amber or red, but intervals drop like a stone.

Not really, they look as I would expect them to really. I'm frustrated with the interval thing, we're in the middle of a holiday in Italy and the the interval said just under 5k to the next service but 1300 odd miles later down autoroutes and autostradas at steady speeds of 80mph, I now need a 'service soon.'

I'm resigned to it really but with two or three oil changes between major services at £300 a pop, costs start to rack up and whilst it isn't a massive concern it's still extra pennies that I could be spending on something else. 2017 Vogue SE

Oddly, the only time mine works as intended is when we're driving to the southern French Alps, then the dpf regens at around 650+ miles and the service interval goes up. Once back in blighty its down to 150 miles between regens wherever and however I drive and the service interval plummets. Still trying to work out why!!

My tailpipes are black, whereas on my L494 there's not a spot of soot on them!

The hunt continues... L405 SV Autobiography LWB SDV8, finished in Aston Martin China Grey by ETO division.

I had my oil cooler replaced a few weeks ago along with an oil change.
Roughly 400 miles later I'm getting a service in 1500 miles. This is crazy for a modern car.
I cant think of any other car I have owned that cant be driven in any manor I choose without having to change the oil every 2000 miles.

This also rings alarm bells when I originally bought the car at 60 miles after a major JLR service. I ended up taking it back in for a reset due to a 1500 miles service light. As I assumed they just forgot to reset it but now i'm thinking they had and its a fault of some kind.
After the reset I had covered around 3600 miles without any issue until the oil was changed after oil cooler replacement.

I've replaced the entire Egr assembly including the cooler, done a high pressure smoke test with no leaks on the intake plenum or throttle body etc. No fault codes at all and also updated the IP cluster firmware that raises the oil dilution threshold from 6% to 7% and still in the UK with motorway journeys I'm getting ridiculous service intervals.

Next thing I guess is an internal inspection of the dpf with a boroscope.

Do you have a Gap iid tool or LR SDD etc. to be able to monitor dpf regeneration intervals, ultimately its this that determines the percentage of oil dilution and in turn the service countdown. Its then just a case of finding why the dpf is regenerating so often! L405 SV Autobiography LWB SDV8, finished in Aston Martin China Grey by ETO division.

I'm fundamentally lazy so unable to attach a gadget to monitor intervals etc and besides, doubtful with my lousy technical knowledge that I could do anything about it anyway. I know others have managed it but I'm not sure what advantage of knowing about regens would give you anyway?

I would have hoped that the long drive down here would have negated any issues but it seems not. 2017 Vogue SE

@Spleen:

The advantage in being able to monitor the regens is in preventing FAILED regens.
This is crucial, because when a regen fails, the car will continue to attempt further multiple regens until successful (or not), each successive failed regen will cause miles to service to plummet further, over and over again!

Being able to spot an upcoming regen means YOU can take charge, and ensure there are as few as possible failed regens, (ideally none at all) thereby saving up all those precious thousands of “miles to service”.

There’s a lot of good advice in this thread, but if you choose to ignore it, you will literally pay dearly, especially if you don’t do your own oil changes.
The way to happiness with your fullfat is to bite the bullet and learn how to keep an eye on your regens, and also learn how to do your own oil changes - you don’t even have to get under the car to do that, and £50 a go is a pittance compared with the dealer. My advice is get reading.  “If it ain’t broke, don’t fix it” -where’s the fun in that?

I manage to avoid failed regens 99% of the time, my problem is the interval between regens is painfully low, hence oil dilution due to many successful regens ultimately bringing down my service interval. As mentioned driving in France 650+ mile intervals, here 150-190 and then a regen. Would love to know why!! L405 SV Autobiography LWB SDV8, finished in Aston Martin China Grey by ETO division.

Thanks, much appreciated. Mine is one of those 'in-betweeners' with the updated 2017 ICP prior to the 2018 facelift so hopefully that process will still work. 2017 Vogue SE

To comment on something @4RRS said. I find when I visit the UK. The car wants to regen more often.
These are the ideas I have had

1. Fuel: the Shell V-Power diesel is different
2. Journey on average are slower
3. Air Quality SDV8 AB MY 2020

I've filled up in France before crossing and just the same, I do however think it's to do with lower cruising speeds and hence lower heat reaching the DPF. L405 SV Autobiography LWB SDV8, finished in Aston Martin China Grey by ETO division.

I am in the UK in October. I will look at my average speeds and the temps. Then report back. I have the 48-month service the week before the trip.

Also since I have started monitoring my regens and making sure they are complete. A few short journeys no longer are a big hit on KM until the next service. SDV8 AB MY 2020
