Thanks for updating interesting news.

Dont let them blame you, its under warranty ask them why? print out and show them your journeys from remote app. Ask them to explain how is it possible it's your driving style? (aka journey length & speed etc ) with this new engin. Which was changed out, to avoid the poor architecture design of the older engines with DPF.

The latest service should at least be FOC, if its under the recommended service mileage, how many miles from last oil change by the way?

I wonder how D300/350 owners are now getting on service light wise, who do less yearly mileage, but still do daily short runs. 2018 SE SDV8 4.4 Byron Blue

It’s done 11,000 miles since the last service.

Ended up having a full first service done early rather than just the oil change as the service advisor said I would end up paying for the oil change twice otherwise as the full service would mean changing the oil again anyway.

This time it’s come on much earlier and there’s still just under 10,000 miles until the full second service is due so it doesn’t make sense to have the second service done early. However I don’t see why I should have to pay for an early oil change due to a clear design fault with the car.

Ironically we had a 17 plate RRS with the SDV6 engine and had 0 problems with oil dilution. Driving style hasn’t really changed since using that car and if anything we are doing more motorway miles now.

They state that it should be every 21,000 miles or 2 years between services yet the car is getting nowhere near that.

I’ve already shown this regarding journeys and apparently 40 miles each way is not far enough for a diesel car apparently. Even though I’ve had no problems with dpf in a Bmw 330d, Mercedes c220d or the RRS SDV6. I’m not just saying this but out of every diesel car I’ve driven this has been by far the worst engine. It constantly hesitates when maintaining a constant speed at around 1700 rpm and feels like it’s jerking. (You can see the needle going up and down between 1,500 and 1,700 rpm at 50mph. Dealer says it’s the car trying to do a regen apparently but I’ve never experienced this with any other diesel car.

Dealer obviously doesn’t give a s**t. Fed up with their attitude tbh.

40 miles is more than adequate. Oil changes every 2 years is not. Personally I’d have it done every 6 months regardless. Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"

For reference most journeys have been motorway journeys 40 miles each way with some short journeys mixed in as well. Car isn’t fit for purpose if it’s still having these problems with this type of usage. Dealer still trying to blame me for not using the car correctly. Bunch of c****


just a theory based on my experience with the 4.4TDV8. I had poor regen and high oil dilution. my thermostat housing was damaged and the engine was running too cool to regen properly. New thermostat cured all.

have a look at the number of attempted regens and the Thermostat (housing and gubbins). get them to test the internal running temp of the engine. If it is running cool (these do anyhow) then it may not be able to complete a full cycle, but pumps diesel into the engine, thus adding to the dilution.

Just a theory mind.
