Mine is a 2020 4.4 SDV8

There are 2 connection profiles Landrover and Rangerover. Use the RangeRover profile and RangeRover 2017-2021 is for facelift SDV8 2018 SE SDV8 4.4 Byron Blue

If your service light came on, you need to immediately change the oil and reset the service counter again. It's easy with a vacuum pump.

I have similar low distance between AR as I live semi rural and have a lot of short journeys. You are also doing a lot of short journeys also and have relatively slow speeds under 60mph etc
Your mileage between Active Regens is low because of this. I can be changing oil between 2000/3000 miles, your distance between AR would be lower if you continually do short journeys, and stop the car during a AR.

It will only increase (distance between AR) once you regularly do long journeys (100-200+ miles) at Motorway speeds as this gets the exhaust temps across dpf above 250-300 Celsius when Passive Regeneration occurs (1). In reality you need +70mph
Throughout the motorway journey the soot load still increases but at a more gradual rate as PR is trying to burn away generated soot load. The algorithm learns from this and mileage between AR will increase.

The PR (1) you saw, was temporary because your dpf exhaust temperature just got up to the 250-300Celsius range then fell back down again. To ensure you maintain PR it has to be on constantly so your DPF temperatures need to be in that range all the time. Having the (1) for a few seconds wont achieve anything. 2018 SE SDV8 4.4 Byron Blue

Thanks Kot,

The problem I have is I still have over 2 years warranty left on the car so I'm going to have to pay for the service. After the warranty is up it's going back to Land Rover for good. Hopefully with the Kot Kit I can reduce my services tho.

I had an Oil Service (interim) on mine in early December and nearly 5000 miles later it's not yet come up with the 'Service Required' message yet, looking at your MPG it is a bit of a giveaway to your use, I travel 33 miles to work along a dual carriageway and a motorway for 28 miles of that journey, so it gets a decent run, and my mpg is in the early thirtees, and your's is showing early twentees.

I buy my own oil from Opie Oils (out of stock at the minute), but my indy does the service for about a ton (Filter and sump plug), and i supply the oil (C1 below)

May I compliment you on your choice of colour!

Wish I read my posts before uploading, I might get some of the spolling correct!

Brilliant, thanks Goldeneye.

The colour was the reason I bought it. I was happy in my Golf edition 35 but the wife wasn't 🤣

If I had known I would have these issues I wouldn't have bought it. The salesman never said anything when I said I live 5 miles away from work and don't do a great deal of miles.

I've done 5k in it now and this will be it's "3rd" service if you include the reset by LR.

My mpg is quite low as I had a full software update to fix some flickering/off screens a couple of weeks back. Well so I'm telling myself but it was averaging 28 ish

I wasn't aware of the oil dilution issue until after I'd bought mine either, retrospectively I'd have been better going for the 5.0 V8 petrol, but I already have a 6.0 V12 in the garage!

Just a quick mention, the Smith & Allen Momentum C1 5W30 is only £22.50/5L delivered if you buy the 20L size, and meets ST JLR.03.5005. Not worth paying premium price if you’re changing oil every 2K-3K miles. “If it ain’t broke, don’t fix it” -where’s the fun in that?

You only need to pay for the yearly/16k service and even then it can be any VAT registered garage but better if the garage can access OSH. That satisfies the requirement for warranty people to have the car serviced as per JLR requirements.
All other interim oil changes do it yourself we all do!
But yeh like many should have bought a petrol.  2018 SE SDV8 4.4 Byron Blue
