Diesels saved Jags bacon in UK , they were very late on the take up !!!!But in all honesty Jags & diesels dont go together . Its a bit like putting a Juke Box In a Church !!
Plus the fact that diesel Jaguars are not the most reliable cars in the world .

I see you have not driven a 2.7 ttd because your take on the diesel Jaguar is completely wrong

I agree on saving Jags bacon as it were, to a degree.

Although a Jag diesel isn't ncessarily what you wouldexpect andcertainly NOT what you think of when you think of a Jag, which is usually luxury, speed and performance, however.......

It's not all bad IMO

Default 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.

My 2007 2.7ttd Jaguar Sovereign goes like a bat out of hell and the fuel economy is great its got 86000 on the clock, although I prefer the shape of my last V8 1997

Interesting observation from my daughter, who is not mechanically minded -- "I can hear my brother's 1980s Bently when it arrives at my door, but I can't hear your Jaguar S-type 2.7D at all when it arrives Dad".
I think this says it all.

Did she have a door/window open when the Bentley arrived and closed when yours arrived? ; -)

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.

Ronbros
Can you get to Santa Pod on June 1st?
A number of us are going from the uk forum.Cambo351 is coming over from Switzerland!
A few of us are staying at the Premier Inn Wellingborough the Friday and/or Sat nights.We do this one at least a couple of times a year.

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.

Default 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??
