So, the previous two posts of my mileage log is for the past 3=/- months. For reference, it gives you an idea of what kind of mileage one CRD driver is getting. The place that the fuel was filled and other data was written in at the time of purchase. With this in mind, the susbsequent MPG will reflect the the impact of the fuel pumped in from the source on the previous line. If someone wants to run some statistics on this, fine with me. Visually, I could see little difference.
Lastly, this may be easier to view if you copy and paste it into Word or Excel and add some spaces/tabs.

As long as the transfer case is in neutral and all four wheels are free wheeling, you do not rack up miles on odometer.
Just an update on the "throttle body" issue. Indeed it is not a throttle body as previously noted. But the tech at the dealer brought me back to let me see it. It looks like on old fashioned automatic choke! It has the butterfly valve and is electronically controlled (what isn't these days!) and the old one was stuck open. The tech, Alvin, told me that the new one was of a different design, so that tells me that it has been a problem too!!
I have driven the CRD now with the latest "new and improved" parts for close to 70 miles without a check engine light or any noticeable problem. It's kind of like waiting for the other shoe to drop! I got used to the check engine light coming on and off at regular intervals! :surprise:
As to the check engine light coming on frequently, all I can say is that stinks. I have had it happen only one time at 586 miles. A software flash took care of that. I run the on-off X 4 with the ignition key to check for codes from time to time and so far none.
I wonder if you got an early build? Except for the software flash and the intercooler hose rupture, my CRD has been perfect.
Sounds like you have a good dealer like I have. Lucky for us!
I am doing a little traveling this weekend and will be blowing the EGR's nose. Have not done it in a while.
Hope this is the last of it for you.
The heater connector can be seen on the 3rd picture. It's the one in the background with the red and black wires.
Unfortunately, we don't have a formatting feature. Some people try to put dots/periods between characters to producing spacing which is slight improvement. An alternative would be to turn your table into a .jpg or .gif image and post it as a picture.

Perhaps the marginal difference is enough to aid the EGR valve at an idle. Is that what you mean?
2. Your oil consumption is normal. My engine used a quart in the first 2k miles. At 16.7k miles it has used 1/8 inch on the dipstick over the last 4.2k miles. Consumption has not stopped but it has definitely slowed way down.
3. If you change your own oil wear a biohazard suit (just kidding). Oil comes out like water, splashes every where and is very difficult to clean from hands and tools.
I sometimes hear the turbo wind down when I shut the engine off but that does not last long enough for me to get outside.
I currently have exactly the condition you describe.
Two other items. Pure highway fuel economy was 31.5 mpg at 62 mph using cruise control. Anyone interested in using Amsoil's 5W-40, I would wait. It appears as if the formulation has been changed. On their website, it is now rated to CF only and not CI-4 when I put it in some months ago. Also,the TBN is now around 8, down from 10+. I may try their 15W-40 in the spring, but will check with the dealer before I use it. I may also contact VM Motori too.

I'm not sure of the operation of the valve. I'm guessing agreeing with your thoughts that it helps at idle and maybe during decell. I know on gas engines the EGR valve is used to cool the combustion temps, When they are high the engine creates much more NOx. This would not be the case of an engine idling or slowing down, maybe diesels create NOx differntly I don't know :confuse: I found info on the Intake throttle valve on VM web site it read (Intake throttle valve-Increased recirculation of gasous emissions,Reduced engine shake during shut down). Maybe someone reading this can help? I'm looking forward to solving some of the CRD mysterys
The second part refers to oil weeping at the block where the turbo bearing oil return line enters the block above the oil filter. I do not have an oil spot on the floor from this either - yet?
It's sad that we aren't the only ones with bad mileage. Some get mileage like us and we're happy that some get mileage like winter2. retmil46 gets 30mpg in Carolina but got 22mpg with texas diesel on his trip to Austin. That might prove it's a fuel issue maybe not good crd's/bad crd's. The name on the store means nothing usually with diesel - the closest tank farm gets the business according to the answer from a refinery engineer whereas gas can have different additive packages at the farm for different brands.
Peace! LK

I am still confused about some things and this is not a reply to anyone directly.
On the CRD the top 2 hoses that look like radiator hoses are connected to the intercooler that is in front of the radiator and the same square area as the radiator. The radiator is right behind the intercooler and about twice as thick as the intercooler. Also the intercooler is an air-to-air intercooler that cools the air that exits the turbo before it enters the intake. The intercooler does not cool the turbo only intake air.
Does it stand to reason that due to efficiency loss whatever the exhaust pressure the turbo outlet pressure would be something less than the exhaust pressure under most conditions? So, the EGR has some pressure differential to allow gases to flow into the intake.
Modern turbochargers are water cooled or they are not cooled, period!? Diesels that have a water cooled turbo can generally be shut down with out waiting since the water in the water jacket around the turbo bearing boils absorbing heat from the bearing hot side.
All modern turbochargers have oil fed through the bearing(s). The oil might have some cooling effect but it does not make the turbo oil-cooled, thus the engine needs to be idled when hot to allow the turbo to cool. Also when under load (which is most of the time) the turbo bearing temperature is at an equilibrium temperature between the hot power side of the turbo and the much cooler compressor side of the turbo. I suspect the turbo bearing is mounted more toward the cool side.
This entire post can be viewed as a statement/question.

you can tell he doesn't have an EVIC. Mine would have said I had "15 mpg to empty" 100 miles before I got to 482 miles, even at my 24 mpg.
How big is a Liberty's tank?
Worked fine for me using the correct search engine.

Very, very similar to mine. If I get up to 60mph, set the cruise, re-set the computer, and can stay at that speed on a level road for 10 or 12 miles, I might see 26 to 26.5. Real world, though, is a different story. I think that some of these claims of consistently getting 28 to 30 mpg must be from people driving 50mph downhill with a tail-wind.

The EGR issue is a fuel problem, namely poor quality and high sulfur. They use the same engine over in Europe and the EGR is a non-issue as I understand. The only difference is the fuel.
ULSD will be here soon and many of the EGR problems should go away.
EU emission standards are different from what they are here so some adaptations have had to been made. Some have been troublesome but in general, the CRD works quite well.
As vehicles become more dependent on computers and software to operate, we can expect to see an increasing number of niggling problems related to them.
Are you satisfied with your investment??
I believe, I have been lucky with my Libby and the mileage she gives me .Most of my travelling is on a 2 lane hiway
50-60mph range,and flat roads.
I have been getting about the same 26mpg,at 60mph,and 28mpg at 53-55mph 1650-1800 rpm's,respectively.
Yesterday I took her in to get serviced at 40 000km's
I had the oil changed,and differentials,Xfer case fluids cleaned out and changed.
I do believe that an oil change using the recommended oil
and standard differential fluid changed from the "standard" to a "synthetic" 75/140,makes a difference.
The engine hardly works now,so I believe it is worth the investment.I am anticipating that in Canada diesel fuel is going to rise to $5 /gal this summer.
I am now getting 30mpg consistantly at 53-55mph ,and 28 mpg at 60 mph.
I will let you know what results I get with a fill up of Shell Ultra premium diesel,soon...
whats your tire pressure at?? I have been running them at 35psi.
Speak Soon...

Did you use 5w40 mobil1 like I just bought? And if so did the change from mobil 5w40 to amsoil 5w40 produce any difference? Are you really considering 15w40 in stead of a provent? I didn't want to provent and I still don't but your concern about intercooler oil like the lost posters is now getting my attention.
I am going to contact my Amsoil dealer to make sure that what I saw on the Amsoil website is correct. I will let you know what he says.
I am considering 15W-40 oil because the viscosity range is narrower and with a 0W or 5W oil. The issue of using a "Provent" type of device never crossed my mind and I do not intend to install one unless it is needed. Also, the 15W-40 oil is designed for diesel. I know that the 5W-40 from Mobil is also.
