Following on from my post regarding my experience of the need of early oil changes on my XJ 2017 (Euro 6) Diesel and the response on the Forum that this was less to do with my driving style and more to do to the architecture of the engine/DPF location.

Assuming that if I continue to use my iCarsoft scanner to monitor the level of oil dilution and have early oil changes before the 7% contamination level - the risk to the engine is small ?

Also as I don't plan to change my XJ ( which I love) for a petrol version in the short term - as the motor trade becomes aware of the need for early oil changes on 2015 or newer (Euro 6) XJ Diesels will the resale price be adversely affected ?

Interestingly, looking at Autotrader, both Independent Dealers and Jaguar Dealerships do not appear to be discounting these models. Also there is only one comment on oil dilution on the Honest John Used Car Review on the XJ and no comment at all on the issue on the What Car or Parkers Used Car Reviews.

Thanks

Tony

My view is no, it won't affect the price. If Jaguar can wiggle out of their responsibility for the issue then I can't see it being a problem for a dealer, Jaguar or independent.
If the oil dilution is kept within tolerance, i.e. the oil is changed with sufficient regularity (however frequently that may be) then there should be no adverse effect on the life of the engine. I for one would not turn away from a newer diesel XJ just as long as I could see it had been serviced at those foreshortened intervals.

Discounting is just admitting that they didn’t care about their product or they weren’t able to make it right. It could however affect the car depreciation when they are out of warranty which is already high compared to rivals. These cars are attractive enough for people even with known issues.

I have 2 customers that are used car dealers & they avoid anything fitted with the JLR 3.0D. Both provide a 12 month aftermarket warranty but it doesn't cover the DPF because it's part of the exhaust system.

That's worrying - the comments to my original post implied that it was only the XJ Diesel (Euro 6 ) 2015 or newer that had the oil dilution issue because it was on the D2a platform and was " medium coupled " whereas models like the XF that are Euro 6 compliant were on the D7a platform, were "close coupled" and therefor not affected at all with the need for early oil changes.
So do you know why those dealers are avoiding pre 2015 3.0 Diesel XJ 's or 3.0 Diesel XF 's ?

Thanks

The spate of broken crankshafts on LR and RR vehicles predated Euro 6 by some margin. Possibly why those Dealers are wary of them - there seems to be no rhyme nor reason for the failures in terms of mileage of usage - although on one forum a respected LR Indy garage owner (who has seen around a hundred Discos with the issue) mentioned that he has seen low oil levels in virtually all the cars he has had in with broken cranks. So maybe there is a common cause.........................?

All examples of broken crankshafts that I have seen on forums are V8 engines because they had two con rod bearings next to one another without any physical boundary. I have read a few examples of TDV6/306DT that used a cheap after market crankshaft which broke.
Let not forget that they have to remove the body from chassis on Disco and RR to repair engine while on Jags that’s not the case.

I don’t see any issues with these engines unless the cars they sell are high mileage or the fact that they have a timing belt will put their customers off. These engines need specialised mechanics while anyone can repair a German or Japanese car and prices are competitive. It’s not like JLR hiding engine rebuild information from even mechanics nor helping with spare parts.

That's pretty much the reason although the wariness started with Disco's snapping their cranks or seizing. Both were amazed that my XFS went past 100K with no major traumas! :D

I suppose the large retailers can absorb the cost of the odd wayward XJ or RRS, but to a small independent it's a big risk when there's a claims limit on the warranty.
