X type 2.0 diesel
Hello All,
I have a 2007 x type 2.0 diesel 80,000 miles on the clock. Just did my own oil, oil filter and air filter change and I must say, I have real satisfaction doing it my self and recommend all to give it a go.My local Jaguar dealership wanted €300 to do just an oil and filter change lol...crazy
The hardest part is removing the plastic engine under tray after that its a piece of cake! Actually one of the easiest cars I have ever done an oil change on.
I used original jaguar oil filter and air filter and castrol magnatech 5w30 oil.
It took me 45mins and that included taking the under tray off tools needed or at least what I used, a small hydraulic jack, a 15mm socket, and a star shaped screwdriver, and a 32mm spanner (I had mine in my motorcycle tool kit for removing the bikes wheel) for removing the oil filter.
It took me 45mins to put the plastic tray back on.
I must say the car is so smooth with the magnatech oil in it, it just purrs down the road.

the new Ford truck 6.7L diesels are as quiet as any petrol engine truck!
amazing how smooth and quiet new diesels are, multi injection events,varied by load on engine. along with timing of injection.
D/engineers have known for many years,why they were so noisey, but couldnt control the mechanical injection accurate enough, pilot inj. helped some.
and of course the new fuels have changed things also.

Ronbros puts his finger right on it when he comments on why modern diesel engines are so quiet.
The original direct injection engines had one passive injection squirt which was entirely mechanically controlled. The burning of the fuel then was like a hammer-blow on the piston crown and cylinder walls. There was one famous wagon 2-stroke diesel here in the UK you could hear coming from around half a mile away. I think it was a Scammel if my memory serves me right, around the 1950s.
Then the indirect injection diesel engine arrived in the 1960s, notably from Peugeot, and BMC's Ricardo engine. This had an "auxilliary" combustion chamber in the cyl. head otherwise known as "the swirl-chamber". Because this was very hot at compression and the swirling air during compression was moving at multi-mach speed, much less noise was created and much higher revs. allowed before engine damage. Drawbacks were hard cold-starting needing glowplugs in the swirl-chamber, and less fuel efficiency by around 20%. But they were ideal for cars and light vans.
With the advent of cheap microprocessors, the HDi or common-rail engine was developed, running at around 25,000Lb/sq" continuous injection pressure, and ACTIVE solenoid-type injectors accurately controlled by the cheap microprocessor. The main feature of these was the "pilot-injection" into the direct style injection chamber. This was a small squirt of fuel ahead of the main squirt to heat up the chamber enough to fire the main injection squirt (pulse). This further reduced noise, partic. idling 'clatter'. Because injection timing is now easily controlled, the inj. timing could be easily retarded at any time, further reducing noise, e.g. during cold-running. A third squirt was used to reduce NOX emissions.
Currently today, the new-ish piezoelectric injectors have practically no mass in the moving part, unlike the electric solenoid type. This gives true electronic timing accuracy with no inertia lag, and up to SEVEN squirts per stroke. This multi-injection has the same effect on noise as slowing down combustion, except there is still the valuable fuel-burning efficiency. With these injectors, control becomes very sophisticated indeed, achieving very similar noise levels to equivalent petrol engines.
The reason the Jag. diesels are so quiet is simply because the noise benchmark from the Jag petrols is so good to start with. At one time the Jag. engines were the the quietest in the world, beating even RollsRoyce and the Japanese. Jag. engineers had to really work at it to make their diesels as quiet as the petrols. A by-product of all this work was to make this type of diesel engine more suitable for driving cars in modern congested traffic than the old petrol engine. This is why on such tests as accelleration from rest the diesels consistently beat the equiv. petrols, due to much better low-rev. torque. Which BTW suits hydraulic automatics far better in any case.
I think the Jag. engineers have achieved their objective.

If you're free on April 6th about 25-30 of us from the .co.uk site so far are meeting at Doncaster
See www.thejagspecialist.com for the address
Hopefully you can get along and meet up there and for a pint with us afterwards.

I would like to meet you guys, but the trip would be difficult to fit my schedule.
i agree with Leeds and buck, so far USA diesels are in light trucks, all of them are quiet, Ford,GM ,Dodge cummins,
BUT Chevy GM is releasing a 2.2L turbo diesel sedan, chevy Kruze,this year, time will tell, engine is produced in Germany, but was engineered by Fiat.
and Mazda is releasing a 2L diesel car this year also!
so the diesels are coming, i wonder who will release a 4.4L twin turbo diesel 1st? in a car?

of interest(for performance minded guys), i was at a race track in Texas, and a guy showed up with a 1998 Ford Mustang coupe, it had a GM diesel engine in it,6.6L with a custom single turbo system, it made a top speed of 205MPH in the standing mile.
all the petrol guys were amazed, lot of comments and questions after the race was over!
and it used a GM hydraulic automatic transmission.
Yes diesels are finally getting some recognition.

IXL, a common cause of failure to start (if the engine isn't cranking at all and seems dead) is a fault in the "park" interlock inhibit switch. This prevents cranking if the lever isn't in 'park'. Sometimes you can get it to work by banging the lever hard into park with just your hand. So look for a bad switch or maladjustment of same. Another similar thing is to observe the headlights during cranking. If they go out completely, there is a bad/dead battery or poor connexions/ground return to same.
If the engine IS cranking, then you have a fault which is harder to diagnose. I would first look for fuel blockage, dirty tank, and clogged fuel filter esp. Starting cranking has its own microprocessor program but is most unlikely to be in error. The glowplugs COULD be a problem if the surrounding temp. is very cold, but as this is a direct injection diesel engine, they aren't used much or for long. The old indirect injection engines were a big glowplug problem, unless they were all working these engines just would not start, and were partic. obstinate.
Can't think of anything else just now.

Induction cleaning
Has any one done induction cleaning on there tdv6, I found a good blog on it and was wondering what other xf owners do??

lets see, in the USA, jaguar dealership started introducing diesel in 2017 maybe 2016? but certainly not before 2015. I think it started with the XE model and them slowly introduced them to the XF model.
At first i thought, wow is loud, compared to my other jaguar. Lots of torque and power yay, but no speed ! God forbids i try to cut people off on the highway, i have to think twice before doing so. I love the fact that you do save money on gas (diesel) while dirving long distances. I have driven from Philadelphia to buffalo NY and i still have 1/4 of s tank left. However, on my normal drive from work to home and vice versa, not much different than my previous Gasoline jaguar....ok ok i get one extra day.
I dont know that i like having to add the DEF all the time (ok every 2000 miles if not less) and Diesel is more expensive than Premiu, gasoline.....
other than that...i think i maybe be siwthicng back to gasoline...and the smell from the diesel not pretty !

DPF Recharge/RED no Amber
2017 XE 20d owner here. I am the only owner.
At 47,500 miles I went directly to the RED DPF Full Warning. No AMBER warning as suggested in the manual.
I took the advice of a local mechanic and drove for 40 minutes on a highway at a decent clip, about 60-75mph. The warning persisted after a restart, suggesting that the recharge process will not kick off on its own/manual cleaning is required. Or potentially a problem with the sensors. The car is also currently in "limp mode", while it drives, it accelerates at a very low pace - similar to the eco setting but a bit slower.
I don't drive this car often anymore as I work from home now (since pre-Covid) but when I do, I am doing 3h round-trips from Massachusetts to New Hampshire. Every once in a while I will take it around town, jumping on the highway to get to the major part of my city, first getting it up to 60-75mph briefly (~10m).
My last round trip to NH was May 8th, the warning came on May 28th, my last fill and DEF top off was March 20th.
I called Jaguar North America and they said "Emissions" are covered until 2024/2025 (state/fed) but could not tell me if my DPF filter was specifically covered, and said my local dealership will let me know what is covered.
I am hoping to go to the service center armed with some historical information from this community. The service center at my local dealership has never been one that I trust - they once tried charging me 1400$ for four brake pads because they have "a special tool" to remove the calipers. I had the brakes done by the previously mentioned mechanic for ~ $300.
I am really nervous to have a problem like this so early, and really nervous that I have to trust the dealership to tell me what is wrong.
Any information would be greatly appreciated, as always, thank you in advance.

HI, this thread is around 12yrs back , the world seems to have turned upside down, from my perspective!
what would happen if we just changed back to regular diesel fuel, did away with DEF completlely???
also electric transportation is coming ON strong, at the price of fossil fuels , its starting to make some sense!
