The update is basically a sticking plaster, It is an after thought to an already well documented problem.
There are several theories surrounding this hypotheses depending on where you glean your information from and seemingly where you live or which country you reside.
First of all the engine, lets assume that is fault free for this example and then concentrate solely on what is making the engine calculate the wrong information and display it incorrectly, The dosing of the Adblu nozzle has in some form a little to do with counting down the miles down, i do not know by how many or how often but there is some opinion from a source that links this to the problem, Secondly the Time to next service, this is factored in to the equasion again i do not know by how many but let's assume it drops by a thousand miles a month, working from the on board calendar it will get it's Date / time etc from the Atomic Clock for GPS purposes etc, this inforation acts together with the AdBlu countdown, Thirdly every time the wheels turn around the miles clock up on the odometer and assuming they count down on the "miles To Nest Service this is working either with or against the Adblu counter and the calendar !
According to the document JLRP00100 the architecture in the JAGUAR vehicles "Utilising the SAME" engines are not affected in the same manner as the Land Rover Product. This it has been suggested is the fault of the Architecture. To glean the info it would be worth reading the document leaked by an employee surrounding Oil Dilution in the form of JLRP00100, It is quite technical in that the wording is contrived but the ethos behind JLR's stance on the situation will come to the surface if you read the content within the explanations as it refers specifically to updates and what actions to take there after.
From the conversations i have been having with many Approved Dealers there is NO remedy certainly for the 2017MY, 2018MY is in some way helping by trying to regulate the dosing and also trying to reduce the numbers of attempted re-gens creating this post injection fuelling which creates heat and also Fuel In Oil, Although some Members have had their Oil tested and subsequently found NO traces of fuel in Oil ?
I'm not at all sure how? this is possible due to the very nature of the combustion process but there you go?
So in short, it's over fuelling, creating too many re - gens and dosing up on AdBlu, the parameters are conflicting and the wrong messages are being displayed !
By the very nature of Combustion i would anticipate Fuel In Oil, Modern Oil is supposed to enhance lubing and decrease wear yet they have extended service intervals on most vehicles, the D5 being 16,000 is quite short in comparrison to most by to days standards, If mine were out of warranty and 3 years old i would be dropping mine at £5K intervals, JLR charging a staggering £450 for the privelidge is absolute robbery and borders on sharp practice if you ask me..... Imagine buying a car that requires a service at 16K miles and they are making £500 a year from it, increase this to a service every 5,000K miles and suddenly youre making £1,500 a year on servicing alone.
A bit like the acientist at Johnson & johnson who came up with the.... If symptoms persist use again in another 7 days.... they sold a minimum of 2 almost straight away.
I doubt there is any substance behind this but then again i doubt very much that JLR have stopped and though't, hang on wer'e making out of this, best give some back as what is happening here is actually not right.
